Apolipoprotein(a), together with apo B-100 the apolipoprotein of Lp(a), is homologeous to plasminogen but lacks fibrinolytic capacity and appeared to interfere with fibrinolysis in in vitro and ex vivo experiments.
|

1386533
|
We determined the correlations between Lp(a) and other blood lipids (serum cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides), coagulation parameters (fibrinogen, factor VII, factor VIII:C fibrin monomers, thrombin-antithrombin III) and fibrinolysis parameters (tissue plasminogen activator antigen, plasminogen activator inhibitor-1 and D-dimer) in 54 patients with essential hypertension, in 65 non-insulin-dependent diabetic patients and in 116 insulin-regulated diabetic patients.

The effect of insulin treatment on the balance between tissue plasminogen activator and plasminogen activator inhibitor-1 in type 2 diabetic patients.
|

1440487
|
In the present prospective follow-up study the effect of 16 weeks insulin treatment and glycemic regulation on plasma levels of tissue plasminogen activator (tPA) and plasminogen activator inhibitor-1 (PAI-1), the main regulators of fibrinolysis, was investigated in 19 type-2 diabetic patients with secondary failure to sulphonylureas.
|
5 |
1440487
|
Compared to 27 healthy subjects levels of tPA and PAI-1 were not significantly increased in type 2 diabetic patients before metabolic intervention.
|
6 |
1440487
|
Although a hypofibrinolytic state due to an increase of PAI-1 levels was previously reported in obese hyperinsulinemic patients, no effect of insulin treatment on both tPA- and PAI-1 levels was observed in the present study including patients with only slightly increased body mass index (median 26.0 kg/m2).
|
7 |
1440487
|
By correlation analysis PAI-1 levels were significantly related to serum cholesterol (R = 0.52) and glycemic control (glucose R = 0.41) in the whole group of diabetic patients at entry and in both subgroups after 16 weeks of treatment (insulin group: cholesterol R = 0.46, HbA1c R = 0.51; sulphonylurea group: cholesterol R = 0.59, HbA1c R = 0.58).
|
8 |
1440487
|
In healthy subjects tPA and PAI-1 was correlated to serum insulin (R = 0.54, R = 0.56) and triglycerides (R = 0.46, R = 0.40).

|
Diabetic CAD patients showed higher TAT levels with clearly increased PAI levels whereas t-PA levels levels were similar in patients and controls.
|
33 |
1579896
|
Long term defibrotide treatment induced marked changes in fibrinolytic parameters of these diabetic patients with CAD with increased t-PA activity, that could be related to an evident reduction of PAI antigen and activity.

Therefore, we measured markers of free radical activity (nonperoxide-conjugated diene isomer of linoleic acid [PL-9,11-LA'] and lipid peroxides expressed as malondialdehyde [MDA]) along with the hemostatic variables: fibrinogen, von Willebrand factor (vWf), plasminogen activator inhibitor (PAI-1), tissue plasminogen activator (t-PA), and plasmin activity (B beta 15-42) in 24 NIDDM patients (12 patients with microalbuminuria and 12 without microalbuminuria) and in 12 age-matched control subjects.
|
35 |
1628764
|
The microalbuminuric diabetic patients had further increases in vWf (P less than 0.03) and t-PA (P less than 0.03) compared with patients with microalbuminuria.

Diabetes is thus associated with increased platelet adhesiveness, increased platelet aggregation with hypersensitivity to proaggregants, increased plasma levels of beta-thromboglobulin and platelet factor 4 as an expression of platelet hyperactivity, increased levels of thromboxane A2 (TXA2) and prostacyclin (PGI2), and reduced levels of tissue plasminogen activator (t-PA).

The Authors studied the behaviour of some prothrombotic (fibrinogen, factor VII, antithrombin III and tissue plasminogen activator) and prethrombotic (beta thromboglobulin, D-dimer) markers in a group of obese subjects in relation to various physiopathological parameters.
|
38 |
1830376
|
For each subject the Authors determined the plasmatic levels of glucose, total cholesterol, triglycerides (enzymatic method, Boehringer kits), fibrinogen (coagulometric method, Organon kit), factor VII (chromogenic method, IL kit), antithrombin III (chromogenic method, IL kit), tissue plasminogen, beta thromboglobulin and D-dimer (ELISA method, Boehringer kits).

|
The fibrinogen plasma levels proved statistically (0.05) increased proportionally to the overweight degree (BMI over 35), cholesterol levels (over 250 mg%) and age (51-65 yrs); factor VII showed a significant increase (0.05) related to the cholesterol levels, the overweight degree and, surprisingly, to female sex; as regards antithrombin III, its sharp reduction was related with ageing and with the "gynoid type" waist/thigh ratio; tissue plasminogen activator showed a statistically significant reduction (0.05) in the group with older age (over 65 yrs); the beta thromboglobulin levels were obviously increased (0.05) in the hypercholesterolemic and hypertriglyceridemic subjects (over 250 mg%), the D-dimer values increased proportionally with age (0.05).

Fibrinolysis was enhanced, as indicated by significant increases in tissue plasminogen activator concentration and the fibrin plate lysis area, with a fall in plasminogen-activator inhibitor activity, suggesting complex formation.
|
45 |

|
Since occlusions in microthromboembolic disease can occur because of deficiencies in tissue plasminogen activator (tPA) and since systemic tPA decreases with an increasing duration of diabetes mellitus, the immunohistochemical localization of tPA in the retinas and choroids of diabetic and nondiabetic patients was investigated.
|
46 |
1899653
|
All but 2 of the 12 insulin-dependent diabetic eyes (IDDM), however, had reduced levels of retinal tPA immunoreactivity which was most pronounced in their peripheral retinas.
|

Selective assay methods show that almost invariably the fibrinolytic activity of these patients is depressed either following increased levels of fibrinolytic inhibitors (mainly plasminogen activator inhibitor 1 or PAI-1) and/or decreased levels of a plasminogen activator (tissue plasminogen activator or t-PA).
|
48 |
2070877
|
Thus two levels of t-PA/increased levels of PAI-1 have been found in obesity, diabetes mellitus, postoperative states, SLE, malignancies, and miscellaneous diseases often complicated with thrombosis such as Behçet's syndrome.

Activity of tissue plasminogen activator and plasminogen activator inhibitor in noninsulin-dependent diabetes mellitus.
|
52 |
2147433
|
The activity of free tissue plasminogen activator (f-tPA) and plasminogen activator inhibitor (PAI) in the plasma of 82 noninsulin-dependent diabetics (NIDDM) was measured by bioimmunoassay of the euglobulin fraction obtained from the plasma, and the levels were compared with those of age- and gender-matched normal subjects.
|
53 |
2147433
|
When glycosylated hemoglobin levels were in excess of 10%, the f-tPA activity was significantly decreased, but no reduction was found in PAI activity as compared with controls.
|
54 |
2147433
|
When NIDDM is associated with either macroangiopathy or high glycosylated hemoglobin levels, a decreased f-tPA activity, rather than an increased PAI activity, may contribute to the development of a defective fibrinolytic state.

|
Tissue plasminogen activator (t-PA), tissue plasminogen activator inhibitor, (PAI), and von Willebrand factor (vWF) were measured in 30 diabetics and 17 control subjects.
|
61 |
2505017
|
The decrease of t-PA activity strongly correlated with greater basal levels of plasminogen activator inhibitor in these same subjects.
|
62 |
2505017
|
In contrast to t-PA activity and PAI, vWF responses to DDAVP inversely correlated to basal vWF concentration in all groups.
|
63 |
2505017
|
In summary, these results suggest that type II diabetic subjects have decreased t-PA activity, which is best explained by increased levels of PAI.
|

|
It has thus been possible to ascertain that the drug has "rheologic" activity, interferes with the function of endothelial cells by stimulating the release of tissue plasminogen activator and thus increases fibrinolytic activity while not interfering with the clotting function and not altering platelet beta-thromboglobulin secretion.

We recently showed that the administration of the antidiuretic V2 specific agonist, 1-desamino[8-D-arginine]vasopressin (dDAVP), to seven male patients with congenital nephrogenic diabetes insipidus (CNDI) did not cause a decrease in blood pressure nor an increase in plasma renin activity or factor VIIIc or von Willebrand factor release.
|
66 |
2559238
|
In the present study, we measured tissue plasminogen activator (activity and antigenicity), von Willebrand factor multimers, plasma and urinary cyclic AMP concentrations following dDAVP or epinephrine administration.
|
67 |
2559238
|
Factor VIIIc and tissue plasminogen activator augmented by 75 to 100% and von Willebrand Factor multimers were increased; plasma renin activity and plasma cyclic AMP concentration increased by 200%.

There were positive and independent correlations between tissue plasminogen activator (tPA) activity after venous occlusion and HbA1c, and between triglycerides and plasminogen activator inhibitor (PAI-1) and tPA antigen concentrations before and after venous occlusion.
|
81 |

Effect of 24 hours of normoglycaemia on tissue-type plasminogen activator plasma levels in insulin-dependent diabetes.
|
83 |
6372155
|
Because recently an immunoradiometric assay for tissue plasminogen activator (t-PA) was developed we measured t-PA levels in 18 uncontrolled insulin-dependent diabetics before and after 24 hr of normoglycaemia induced by insulin to look for a modification of endothelial cells function.
|
84 |
6372155
|
After 24 hr of strict control, plasma free insulin levels rose significantly, total t-PA R-Ag, its active fibrin binding fraction and euglobulin fibrinolytic activity were significantly decreased.
|
85 |

|
These results suggest a responsibility for insulin in the decrease in t-PA blood level and could explain at least partially the relation between hyperinsulinism, thrombosis and atherogenesis.

|
The levels of thrombin antithrombin III complex (p < 0.05), D-dimer (p < 0.05), tissue plasminogen activator (p < 0.005) and PA inhibitor 1 (p < 0.01) were significantly increased, while the level of thrombomodulin (p < 0.005) in the fasting plasma was significantly decreased in the WS cases compared with N.

Because of the potential importance of plasmin generation in these processes, we evaluated the effect of elevated glucose concentrations on expression of plasminogen activator inhibitor-1 (PAI-1), tissue plasminogen activator (tPA), and urokinase (uPA) in cultured bovine brain endothelial cells (BBEC) versus cultured bovine aortic endothelial cells (BAEC).
|
89 |
7519664
|
Expression of tPA mRNA was not affected by the glucose concentration of the medium, and uPA mRNA was not detected in our BBEC cultures.
|
90 |
7519664
|
A decrease in the local tissue activity of PAI-1 by elevated glucose concentrations, with no effect on tPA or uPA expression, would lead to an increase in the plasmin activity and thereby predispose neural tissues, such as the cerebrum and retina, of diabetic patients to neovascularization.

|
Incubation of washed platelets in Tyrode buffer, pH 7.5, with insulin (200 microU/ml) and CaCl2 (1.2 mM) at 37 degrees C for 3 h resulted in a threefold increase of plasminogen activator activity in the supernatant over the basal level as determined by both the amidolytic assay and the proteolysis of alpha-casein through the formation of plasmin from plasminogen.

Tissue-plasminogen activator, plasminogen activator inhibitor and risk of peripheral arterial disease.
|
98 |
7669086
|
In this population-based case-control study, we examined the relationship between the fibrinolytic variables tissue-plasminogen activator (t-PA) antigen and plasminogen activator inhibitor (PAI) activity, cardiovascular risk factors and peripheral arterial disease.
|
99 |
7669086
|
Mean levels of t-PA antigen and PAI activity were significantly elevated in 121 cases compared to 126 controls.
|
100 |
7669086
|
The increased risks of peripheral arterial disease with increasing PAI activity and t-PA antigen levels were partly mediated by interactions with serum triglycerides, high density lipoprotein (HDL) cholesterol and cigarette smoking.
|
101 |
7669086
|
For example, adjustment for triglycerides significantly reduced the odds of disease for PAI activity from 1.41 (95% confidence intervals 1.08, 1.86) to 1.24 (0.93, 1.65) and from 1.47 (1.09, 1.98) to 1.34 (0.99, 1.82) for t-PA antigen.
|
102 |
7669086
|
We conclude that impaired fibrinolytic potential (raised PAI activity and t-PA antigen) is associated with peripheral atherosclerosis and that this relationship is partly influenced by lipids and cigarette smoking.

For example, adjustment for triglycerides significantly reduced the odds of disease for PAI activity from 1.41 (95% confidence intervals 1.08, 1.86) to 1.24 (0.93, 1.65) and from 1.47 (1.09, 1.98) to 1.34 (0.99, 1.82) for t-PA antigen.
|

We conclude that impaired fibrinolytic potential (raised PAI activity and t-PA antigen) is associated with peripheral atherosclerosis and that this relationship is partly influenced by lipids and cigarette smoking.

The effects of contraceptive steroids on the expression of endothelial homeostasis were examined by direct and indirect measures in women with insulin-dependent diabetes mellitus (IDDM) in a prospective nonrandomized controlled study.
|
114 |
7968593
|
In the indirect assessment of endothelial function, we found a proportionate increase in plasma levels of thrombin-antithrombin III (TAT) complexes and D-dimer during treatment.
|
115 |
7968593
|
Hormonal intake was followed by decreased antigen concentrations of tissue plasminogen activator (t-PA) and plasminogen activator inhibitor (type 1 [PAI-1]), whereas the activities of t-PA and PAI-1 were unchanged.
|
116 |
7968593

Oral glucose tolerance tests were performed in 318 randomly selected healthy men and 324 women aged 25 to 64 years. tPA activity was strongly predicted by fasting insulin in both univariate analysis (r = -.37 and -.34 in men and women, respectively) and multivariate analysis with age, anthropometric measurements, lipids, and blood pressure included.
|
123 |
7990715
|
Fasting insulin was the strongest predictor of PAI-1 activity (r = .49 and .51).
|
124 |
7990715
|
In women, the influence of fasting insulin level on tPA and PAI-1 activity was consistently stronger after than before menopause, and a threshold effect was seen with distinctly lower fibrinolytic activity in the highest quartile of insulin (> 7.0 mU/L).
|
125 |
7990715
|
Subjects with previously unknown diabetes or impaired glucose tolerance tended to have elevated fibrinogen and PAI-1 activity and decreased tPA activity.
|
126 |
7990715
|
Our data support previous findings of a strong correlation between insulin and PAI-1 activity in small highly selected groups, and extend them to randomly selected population samples.
|
127 |

|
The strong inverse relation between endogenous insulin levels and tPA activity has not previously been demonstrated in a healthy population.

|
Plasma levels of t-PA (tissue plasminogen activator) and t-PA-PAI-1 (plasminogen activator inhibitor-1) complex increased with increase in age, but those of PAI-1 (total and free) did not change in controls.
|
129 |
8236167
|
Plasma levels of t-PA, t-PA-PAI-1 complex, free and total PAI-1 increased with increase in body mass index in controls, but no significant changes were shown in these parameters in DM patients.
|
130 |

Microalbuminuria in insulin-dependent diabetes mellitus (IDDM) patients has been related to abnormalities in haemostasis, poor glycaemic control, disadvantageous alterations in the lipid spectrum and elevated concentrations of lipoprotein(a), another independent risk factor for cardiovascular disease.
|
132 |
8250495
|
No significant differences were found in blood lipids (Lp(a), serum cholesterol, low-density lipoprotein and high-density lipoprotein cholesterol and triglycerides), glycaemic control (HbA1c) and several haemostasis parameters (factor VII, VIII, fibrin monomer, thrombin-antithrombin III, D-dimer, tissue plasminogen activator antigen and plasminogen activator inhibitor-1) between the micro- and normoalbuminuric subgroups.
|
133 |
8250495
|
In the microalbuminuric subgroup increased concentrations for plasminogen and alpha 2-antiplasmin were measured.
|
134 |

|
PAI-1 and factor VII activity are higher in IDDM patients with microalbuminuria.
|
135 |
8314015
|
Microalbuminuria is associated with an increased risk of cardiovascular disease (CVD) in insulin-dependent diabetes mellitus (IDDM) patients, but the pathophysiological basis of this association is not clear.
|
136 |
8314015
|
To see whether or not hemostatic dysfunctions might contribute to explain this association, we measured tissue plasminogen activator (t-PA), plasminogen activator inhibitor-1 (PAI-1), factor VII activity, plasma fibrinogen, and plasma endothelin-1 (ET-1) in 13 microalbuminuric (albumin excretion rate [AER], 20-200 micrograms/min) and in 13 comparable normoalbuminuric (< 20 micrograms/min) IDDM patients. t-PA and ET-1 were similar in the two groups, whereas PAI-1 activity (5.65 +/- 1.92 vs. 0.85 +/- 0.58 IU/ml, P < 0.05), factor VII (87.85 +/- 4.94 vs. 76.54 +/- 2.31%, P < 0.05), and plasma fibrinogen (3.38 +/- 0.21 vs. 2.65 +/- 0.13 g/l, P < 0.05) were significantly higher in microalbuminuric than in normoalbuminuric patients.
|
137 |
8314015
|
Plasma fibrinogen was related to AER (r2 = 0.23, P < 0.05), whereas triglycerides and factor VII were related to PAI-1 (r2 = 0.39, P < 0.001 and r2 = 0.10, P < 0.05).

In this study we examined fibrinopeptide A, tissue plasminogen activator and plasminogen activator inhibitor plasma levels in Type 1 diabetic patients compared to matched healthy normal controls, and the effect of induced hyperglycaemia on these parameters.
|
139 |
8339853
|
Fibrinopeptide A and plasminogen activator inhibitor were increased while tissue plasminogen activator was decreased in Type 1 diabetic patients, in the basal state.
|
140 |

The coagulation parameters (fibrinogen, prothrombin time, partial thromboplastin time with kaolin, von Willebrand factor antigen) did not differ between patients and control subjects either before or after 20 min of venous occlusion.
|
148 |
8382139
|
In the diabetic patients, chronic activation of the fibrinolytic system was found at baseline, which was indicated by a shortened euglobulin lysis time (P < 0.01), increased tissue plasminogen activator activity (P < 0.05) and decreased plasminogen activator inhibitor type 1 antigen level (P < 0.05), when compared with control subjects.
|
149 |
8444504
|
The following factors were thus assessed: lipid factors: cholesterol, triglycerides, high density lipoprotein cholesterol, low density lipoprotein cholesterol, apolipoprotein AI, apolipoprotein B; coagulation factors: fibrinogen, antithrombin III, fibrinopeptide A, factor VIII coagulant, factor VIII antigen, protein C; factors of physiological fibrinolysis: plasminogen, alpha 2-antiplasmin, tissue plasminogen activator and euglobulin clot lysis time before and after venous occlusion, plasminogen activator inhibitor before venous occlusion; and factors of platelet release: beta-thromboglobulin, platelet factor 4.
|
150 |
8444504
|
There were no differences in lipid factors, but significant differences were observed in hemostatic variables: fibrinogen (without restenosis: 3.18 +/- 0.83; restenosis: 3.83 +/- 0.51 milligrams, p = 0.05), tissue plasminogen activator before venous occlusion (without restenosis: 10.9 +/- 26.8; restenosis: 232.5 +/- 371.2 IU, p < 0.04), euglobulin clot lysis time after venous occlusion (without restenosis: 176.5 +/- 100.5; restenosis: 78.6 +/- 40.2 min, p < 0.05) and for marker of the platelet release: platelet factor 4 (without restenosis: 10.8 +/- 7.9; restenosis: 20.5 +/- 7.5 ng/l, p < 0.04).

To investigate sex differences in coagulation and fibrinolysis in NIDDM, we measured levels of fibrinogen, factor VII:C, von Willebrand factor, plasminogen activator inhibitor-1, and tissue plasminogen activator in 213 NIDDM subjects (124 men and 89 women) who were not receiving insulin therapy.
|
154 |
8548417
|
The women had higher levels of factor VII:C (144% versus 120.5% in men, P < .0005) and plasminogen activator inhibitor-1 activity (25.6 versus 17.0 U/mL), and these differences remained significant when account was taken of the higher body mass index (29.6 versus 28.0 kg/m2, P = .02), glycosylated hemoglobin (7.2% versus 6.8%, P < .05), and cholesterol levels (6.3 versus 5.7 mmol/L, P < .0005) in women than men.
|
155 |
8548417
|
In contrast, levels of fibrinogen (3.2 versus 3.1 g/L), tissue plasminogen activator antigen (10.6 versus 11.2 ng/mL), and von Willebrand factor (1.27 versus 1.23 IU/mL) were no different between women and men, respectively.
|
156 |
8548417
|
These results suggest that elevated levels of plasminogen activator inhibitor-1 and factor VII:C may contribute to the increased cardiovascular risk of NIDDM that is particularly marked in women.

We found that all-cause mortality was significantly associated with increased levels of vWF and tPA.
|
163 |

For vascular mortality there was a significant association with all three haemostatic variables (tPA, PAI-1, vWF).
|
164 |
8584993
|
In multivariate Cox regression analysis (including: age, sex, smoking habits, body mass index, diabetes mellitus, hypertension, tPA, PAI-1, and vWF), vWF and smoking were independently significantly associated with all-cause mortality, and tPA and age with vascular mortality.

|
In the present study, we examined if proinsulin and insulin affect the constitutive (fasting) secretion of plasminogen activator inhibitor type 1 (PAI-1) and tissue plasminogen activator (t-PA) in young healthy women (N = 17).
|
168 |
8692017
|
We also measured the antigen concentrations of PAI-1 and t-PA during slow and fast changes in proinsulin and insulin levels induced by oral (OGTT) and intravenous (IVGTT) glucose tolerance tests.
|
169 |
8692017
|
We observed no consistent correlations between fasting values of proinsulin, insulin, PAI-1, and t-PA either before or during hormonal treatment.
|
170 |
8692017
|
Before hormonal treatment, PAI-1 and t-PA antigen levels decreased (P < .05) during the hyperproinsulinemia and hyperinsulinemia induced by the OGTT and IVGTT.
|
171 |
8692017
|
After hormonal intake for 6 months, a decrease only in t-PA concentrations during the OGTT was observed despite similar proinsulin and insulin responses to the glucose loads.
|
172 |

It has been shown recently in epidemiological studies, that increased concentration of several factors, mainly fibrinogen, factor VII, von Willebrand factor (vWF), and the fibrinolytic variables plasminogen activator inhibitor 1 (PAI-1) and tissue plasminogen activator (t-PA), can be considered as risk factors for CHD.
|
184 |
8862693
|
In fact, it has been shown that the fibrinolytic parameters PAI-1 and t-PA antigen are strongly related to the metabolic disorder of insulin resistance, whereas the link with fibrinogen, factor VII, and vWF remains weak.
|
185 |
8862693
|
Many cross-sectional studies conducted in different populations have shown that PAI-1 and t-PA antigen (which represents t-PA/PAI-1 complexes) are strongly correlated with insulin, triglyceride, high-density lipoprotein (HDL) cholesterol, body mass index, walst-to-hip ratio and blood pressure, and that the improvement of insulin resistance improves in parallel the metabolic abnormalities and the concentration of the fibrinolytic parameters.
|
186 |
8862693
|
Attempts at explaining the elevated PAI-1 and t-PA antigen levels in the insulin resistance syndrome have involved many clinical and in vitro studies, in which the role of insulin, insulin propeptides, very-low-density lipoprotein (VLDL) triglyceride, insulin resistance per se, glucose, and adipose tissue have successively been analysed and the main results of these studies are presented in this review.
|
187 |
8862693
|
Due to recent experimental data from animal models of thrombosis, a pathogenic role of decreased fibrinolytic activity or increased PAI-1 levels can be proposed and could play a role in the development of vascular disease in subjects with Type 2 diabetes or insulin resistance.

This study attempted to verify the existence of a relationship between oxidative stress documented by malondialdehyde (MDA) and superoxide dismutase (SOD) and fibrinolysis analysed by tissue plasminogen activator (tPA) and its inhibitor (PAI-1) in diabetes mellitus.
|
194 |
8891455
|
The following were analysed: plasma MDA concentration, SOD activity in erythrocytes, tPA activity and antigen, PAI-1 activity and antigen, fasting blood glucose, fructosamine, glycated haemoglobin (HbAlc), and urine albumin.
|
195 |
8891455
|
This contrasted with an increased plasma MDA concentration especially in Type 2 diabetes as compared with Type 1 or healthy persons (p < 0.001). tPA activity was increased in both groups of patients with diabetes as compared to healthy persons (p < 0.001), PAI-1 activity was higher in Type 2 diabetes with vascular changes than in the remaining subgroups (p < 0.001).
|
196 |
8891455
|
Multivariate analysis revealed a significant positive relationship between plasma MDA concentrations and PAI-1 antigen (r = 0.53, p < 0.001) and a negative relationship between SOD and tPA activities (r = -0.53, p < 0.01).

Plasma fibrinolytic potential is reduced in NIDDM and it is known that glucose and insulin can modulate plasminogen activator inhibitor (PAI-1) and tissue-plasminogen activator (t-PA) secretion and can therefore regulate local fibrinolysis.

After 24 h, PAI-1 and t-PA antigens and activity were evaluated in the culture medium; in cells exposed to 20 mmol/l glucose and to 0.5 nmol/l insulin PAI-1 gene expression was also evaluated.
|
200 |
8960822
|
An increase in PAI-1 antigen was observed at each glucose concentration (by 138, 169, 251 and 357% as compared to 5 mmol/l glucose) which was paralleled by an increase in PAI-1 activity. t-PA concentration was also increased by glucose but its activity was sharply reduced.
|
201 |
8960822
|
An increase in PAI-1 antigen was detected at each insulin level (by 121, 128, 156 and 300% as compared to no insulin).
|
202 |
8960822
|
PAI-1 activity was slightly increased at the lowest insulin concentrations but markedly increased by 10 nmol/l insulin. t-PA antigen was also increased by insulin; however, its activity was markedly reduced at each concentration.
|
203 |

206 |
9179544
|
Plasma levels of lipoprotein(a) [Lp(a)], tissue plasminogen activator (tPA) and plasminogen activator inhibitor type 1 (PAI-1) were assessed in addition to anthropometry and levels of glucose, total cholesterol, triglycerides, high-density lipoprotein (HDL), low-density lipoprotein (LDL) and apo A1 and B in 73 patients (36 men and 37 women) with primary hyperlipidaemia (group NDHL) in Kuwait.
|
207 |
9179544
|
Lp(a) levels (212 mg L-1, 8-600 mg L-1, median and range) were similar to those obtained in a matched group of 32 non-insulin-dependent diabetes mellitus (NIDDM) patients with hyperlipidaemia (218 mg L-1, 50-610 mg L-1) and slightly higher, although not significantly so (P = 0.06), than levels seen in 68 healthy normolipidaemic control subjects (182 mg L-1, 70-488 mg L-1). tPA levels (8.4 ng mL-1, 3.8-18.4 ng mL-1, median and range) in group NDHL were lower than in the diabetic group (11.4 ng mL-1, 5.2-14.2 ng mL-1) but higher than in the healthy control subjects (7.4 ng mL-1, 2.8-12.6 ng mL-1).
|
208 |
9179544
|
Hyperlipidaemia phenotype (hypercholesterolaemia or hypertriglyceridaemia) did not influence tPA and PAI-1 levels, but Lp(a) levels were significantly lower with hypertriglyceridaemia.
|
209 |
9179544
|
Gender, cigarette smoking and racial origin (Kuwaitis, other Arabs or South Asians) did not affect Lp(a), tPA and PAI-1 levels, but tPA levels were higher in postmenopausal subjects.
|
210 |
9179544
|
PAI-1 levels correlated with tPA and triglyceride (TG) levels in the groups of subjects (normo- and hyperlipidaemic).
|
211 |
9179544
|
In the normolipidaemic control group, the significant associations of tPA and PAI-1 were with body mass, expressed as the body mass index or the waist-hip ratio.
|
212 |
9179544
|
These results suggest that different factors influence the plasma levels of the prothrombotic factors Lp(a), tPA and PAI-1 in healthy control subjects and in patients with hyperlipidaemia.
|
213 |
9179544
|
In the latter, hyperlipidaemia phenotype, age, glycaemic status and uric acid levels are important determinants of the levels of these prothrombotic variables, whereas in the healthy, young control population, body mass was the single important association with tPA and PAI-1.

In the selected study population of 81 men and 19 women with fibrinogen concentration either > or = 3.5 g/l (n = 70) or < or = 2.5 g/l (n = 30) hyperfibrinogenemia was found to be significantly associated with increased concentrations of plasmin-alpha 2-antiplasmin complex [PAP [median (25.-75. percentile)], 534 (361-680) micrograms/l vs. 289 (243-440) micrograms/l; p < 0.001] and tissue plasminogen activator (t-PA) antigen [9 (6-11) micrograms/l vs 8 (5-9) micrograms/l; p < 0.05] while this association was lost in the subgroup of patients with angiographically normal coronary arteries (n = 26).
|
224 |
9184412
|
In addition to these findings fibrinogen was significantly correlated with PAP (r = 0.40, p < 0.001; n = 224) and t-PA antigen (r = 0.2, p < 0.01; n = 224) after adjustment for age, diabetes mellitus, lipid parameters and leucocyte counts.

Increased blood plasminogen activator inhibitor-1 and intercellular adhesion molecule-1 as possible risk factors of atherosclerosis in Werner syndrome.
|
226 |
9187938
|
PAI-1 is a potent inhibitor of tissue plasminogen activator and a possible risk factor of atherosclerosis.
|
227 |
9187938
|
One of the well-known physiological substances that induce the PAI-1 gene is tumor necrosis factor-alpha, which also induces other possible risk factors of atherosclerosis, intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1.
|
228 |
9187938
|
We conclude that high concentrations of PAI-1 and ICAM-1 in blood may be one of the potent causes of severe atherosclerosis in Werner syndrome.

9201602
|
The purpose of this study was to examine the potential relationship of tissue plasminogen activator-plasminogen activator inhibitor-1 (tPA-PAI-1) complexes and diabetic complications in individuals with insulin-dependent diabetes mellitus (IDDM).
|
231 |
9201602
|
Higher levels of tPA-PAI-1 complexes were seen for both men and women with IDDM complications.
|
232 |
9201602

All subjects were tested on the following parameters: fibrinogen, factor VII, prothrombin fragment 1 + 2 (F1 + 2), thrombin-antithrombin III complexes (TAT), tissue plasminogen activator (t-PA) antigen (Ag) before and after venous occlusion (VO), and plasminogen activator inhibitor type-1 (PAI-1) activity pre- and post-VO.
|
238 |
9258277
|
At baseline, obese nondiabetic subjects, lean NIDDM patients, and especially obese NIDDM patients displayed significantly (P < .01) higher levels of fibrinogen, factor VII, F1 + 2, TAT, t-PA(Ag) pre-VO, and PAI-1 pre- and post-VO and significantly (P < .01) lower levels of t-PA(Ag) post-VO.
|
239 |
9258277
|
In obese NIDDM patients treated with heparin fibrinogen, factor VII, F1 + 2, TAT, t-PA(Ag) pre-VO, and PAI-1 pre- and post-VO levels significantly (P < .01) decreased and t-PA(Ag) post-VO levels significantly (P < .01) increased at the end of treatment.
|
240 |
9283213
|
We measured thrombin.antithrombin III complex (TAT), alpha 2-plasmin inhibitor plasmin complex (PIC), D-dimer, protein C, protein S, thrombomodulin (TM), vitronectin, tissue plasminogen activator.plasminogen activator inhibitor-1 complex (tPAI-C) in theses two groups.

The aim of study was the evaluation of tissue plasminogen activator (t-PA) and its inhibitor (PAI-1) in the II type diabetes on the base of the common fibrinolytic system tests as euglobulin lysis time (ELT) and the concentration of fibrin/fibrinogen products (FDP).
|
242 |
9296893
|
In the blood the following determinations were performed: antigen of t-PA and PAI-1, ELT and FDP.
|
243 |
9296893
|
In the blood of patients with II type diabetes increased. t-PA Ag and PAI-1 Ag concentrations were observed.
|
244 |
9409310
|
The two groups did not differ as to the plasma levels of tissue plasminogen activator or plasminogen activator inhibitor-1.
|
245 |
9409313
|
Significantly increased levels of thrombin-antithrombin III complexes (P < .01), prothrombin fragments 1 + 2 (P < .01), and D-dimers (P < .01) were found 1 hour, as well as 24 to 48 hours, after PTA.
|
246 |
9409313
|
Restenotic patients as a whole had higher plasma fibrinogen (3.46 +/- 1.12 versus 2.95 +/- 0.62 g/L, P < .01) and C-reactive protein (25.4 +/- 46.7 versus 7.9 +/- 6.9 mg/L, P < .05) at baseline, as well as higher fibrinogen (P < .05) and prothrombin fragments 1 + 2 (P < .01) during months 3 to 6 after PTA.
|
247 |
9409313
|
There was a nonsignificant tendency for higher values of von Willebrand factor (206 +/- 98% versus 184 +/- 100%, P = .2) at baseline in patients with restenosis, whereas tissue plasminogen activator, plasminogen activator inhibitor, coagulation screening tests, blood cell counts, and serum lipids showed no significant difference between the two groups.
|
248 |
9409313
|
Patients with critical limb ischemia (stage III/IV, Fontaine) had significantly higher fibrinogen and von Willebrand factor at repeated points of time, as well as significantly higher C-reactive protein and lower creatinine clearance at entry.
|
249 |
9522977
|
Although systemic tissue plasminogen activator (t-PA) and urokinase-like plasminogen activator (u-PA) levels showed no significant differences from normal adults, enhanced fibrinolysis was indicated by elevated D-dimer and low plasminogen levels in the neonates in this study.
|
250 |
9544728
|
They also had a higher prevalence of hypertension, higher mean levels of fasting serum triglyceride, slightly lower mean levels of serum high-density-lipoprotein cholesterol, and higher mean levels of plasma plasminogen activator inhibitor-1 and tissue plasminogen activator (antigen).
|
251 |
9562351
|
To investigate the metabolic and genetic associations of levels of soluble adhesion molecules, plasma levels of soluble E-selectin and vascular cell adhesion molecule-1 were measured in 60 non-insulin-dependent diabetes mellitus (NIDDM) patients, 60 first-degree relatives of NIDDM patients and 60 control subjects, none of whom displayed clinical features of vascular disease.
|
252 |
9562351
|
E-selectin levels correlated with triglycerides, tissue-plasminogen activator and plasminogen activator inhibitor-1 activity in all groups.
|
253 |
9562351
|
In controls and patients vascular cell adhesion molecule-1 levels correlated with von Willebrand factor (vWF).

Previous studies have demonstrated that low density lipoproteins (LDLs) stimulate the production of plasminogen activator inhibitor-1 (PAI-1) and reduce the generation of tissue plasminogen activator (tPA) in vascular endothelial cells (ECs).
|
255 |
9672075
|
The present study investigated the effect of glycated LDL on the production of PAI-1 and tPA in cultured human umbilical vein ECs (HUVECs).
|
256 |
9672075
|
Glycation increased the abundance of glucitollysine and conjugated dienes in LDL and amplified the overproduction of PAI-1 and the reduction in tPA generation from HUVECs induced by LDL.
|
257 |
9672075
|
Treatment with 25 mmol/L aminoguanidine, an antioxidant and inhibitor of the formation of advanced glycation end products, during glycation normalized glycated LDL-induced generation of PAI-1 and tPA in ECs.
|
258 |
9672075
|
The results of the present study indicate that glycation enhances the production of PAI-1 and attenuates tPA synthesis in ECs induced by LDL, which may contribute to the increased incidence of cardiovascular complications in diabetes.

Tissue plasminogen activator (tPA) is the major plasminogen activator responsible for dissolving blood clots found in blood vessels.
|
262 |
9763537
|
In addition, plasminogen activator inhibitor type 1 (PAI-1) activity was found to be significantly and positively associated with tPA antigen concentration (P<0.001).
|
263 |
9763537
|
A multivariate analysis identified chronic low-dose aspirin therapy (P<0.001), PAI-1 activity (P<0.001), hypertriglyceridemia (P=0.005), the type of angina (P=0.026), multivessel disease (P=0.041), and hypercholesterolemia (P=0.043) as significant and independent determinants of tPA antigen.
|
264 |
9763537
|
The relation of tPA antigen to PAI-1 activity furthermore underlines the relation between tPA antigen concentration and a prothrombotic state.

Both oxidized LDL and advanced glycation endproduct (AGE) activate endothelial cells with down-regulating thrombomodulin and tissue plasminogen activator(t-PA) expression.
|
268 |
9796307
|
Moreover the oxidized LDL and AGE up-regulate the expression of tissue factor, and t-PA inhibitor, PAI-1.

High plasminogen activator inhibitor and tissue plasminogen activator levels in plasma precede a first acute myocardial infarction in both men and women: evidence for the fibrinolytic system as an independent primary risk factor.
|
271 |
10090351
|
In addition, the effects of ACE-I on plasma levels of plasminogen activator inhibitor (PAI-1) and of tissue plasminogen activator (TPA) were studied.
|
272 |
10090351
|
PAI-1 levels in NIDDM were similar to those in control subjects, whereas TPA levels were about 25% lower in patients than in control subjects (P = .013).
|
273 |
10090351
|
In contrast, plasma levels of cE-selectin, cICAM-1, PAI-1, and TPA were unaffected.
|
274 |

|
Prospective studies show that increased tissue plasminogen activator (tPA) antigen increases the risk of cardiovascular mortality.
|
275 |
10102462

C-reactive protein in healthy subjects: associations with obesity, insulin resistance, and endothelial dysfunction: a potential role for cytokines originating from adipose tissue?
|
277 |
10195925
|
C-reactive protein, a hepatic acute phase protein largely regulated by circulating levels of interleukin-6, predicts coronary heart disease incidence in healthy subjects.
|
278 |
10195925
|
In this study we have sought associations of levels of C-reactive protein and interleukin-6 with measures of obesity and of chronic infection as their putative determinants.
|
279 |
10195925
|
We have also related levels of C-reactive protein and interleukin-6 to markers of the insulin resistance syndrome and of endothelial dysfunction.
|
280 |
10195925
|
We performed a cross-sectional study in 107 nondiabetic subjects: (1) Levels of C-reactive protein, and concentrations of the proinflammatory cytokines interleukin-6 and tumor necrosis factor-alpha, were related to all measures of obesity, but titers of antibodies to Helicobacter pylori were only weakly and those of Chlamydia pneumoniae and cytomegalovirus were not significantly correlated with levels of these molecules.
|
281 |
10195925
|
Levels of C-reactive protein were significantly related to those of interleukin-6 (r=0.37, P<0.0005) and tumor necrosis factor-alpha (r=0.46, P<0.0001). (2) Concentrations of C-reactive protein were related to insulin resistance as calculated from the homoeostasis model assessment model, blood pressure, HDL, and triglyceride, and to markers of endothelial dysfunction (plasma levels of von Willebrand factor, tissue plasminogen activator, and cellular fibronectin).
|
282 |
10195925
|
These data suggest that adipose tissue is an important determinant of a low level, chronic inflammatory state as reflected by levels of interleukin-6, tumor necrosis factor-alpha, and C-reactive protein, and that infection with H pylori, C pneumoniae, and cytomegalovirus is not.
|
283 |
10342820
|
Furthermore, plasminogen activator inhibitor type 1 (PAI-1) activity, tissue plasminogen activator antigen levels, von Willebrand factor antigen levels, tissue factor pathway inhibitor (TFPI) activity, and endothelin-1 levels were measured.
|
284 |
10342820
|
TFPI activity was elevated, and PAI-1 activity was reduced in the type 1 diabetic patients.
|
285 |
10342820
|
Furthermore, PAI-1 activity was positively correlated with urinary albumin excretion (r = 0.48, P < 0.01) and inversely correlated with the vasodilatory response to the highest ACh dose (r = -0.37, P < 0.05).
|
286 |
10354125
|
Among the diabetes/IGT group, median levels of fibrinogen, von Willebrand factor (VWF), tissue plasminogen activator (t-PA), fibrin D-dimer and plasma viscosity were higher in subjects with PAD than those without PAD (P </= 0.05).
|
287 |
10354125
|
After separate adjustment for fibrinogen, VWF, t-PA, fibrin D-dimer, leucocyte elastase, plasma viscosity and haematocrit, those with diabetes/IGT no longer had a significantly higher risk of PAD compared to those with a normal glucose tolerance test.
|
288 |
10364089
|
During CsA, but not azathioprine, plasma tissue plasminogen activator antigen and plasminogen activator inhibitor-1 levels correlated significantly with prostaglandin E2 (r=0.53, P=0.02; and r=0.60, P=0.008, respectively), and thromboxane B2 (r=0.75, P=0.0001; and r=0.77, P=0.0001, respectively) levels.
|
289 |
10369792
|
UAER was measured together with selected markers of haemostatic function-vWF, tissue plasminogen activator (tPA), plasminogen activator inhibitor, factor VII and fibrinogen-in healthy volunteers aged 40-65 years.
|
290 |
10369792
|
Baseline vWF and tPA were both positively correlated to the change in UAER during follow-up (r=0.26, P=0.04 and r=0.40, P=0.001 respectively).
|
291 |
10369792
|
The mean UAER increased significantly by 7.6 microgram/min and 7.5 microgram/min respectively in subjects with vWF and tPA above the medians at baseline (P=0.01 and P=0.003 respectively), whereas no changes in UAER were seen in subjects with vWF and tPA below the medians.
|
292 |
10369792
|
High plasma concentrations of vWF and tPA are associated with progression of UAER in clinically healthy subjects.
|
293 |
10369792
|
Both vWF and tPA are secreted by endothelial cells and the results suggest that endothelial dysfunction leads to progression of UAER.
|

Atherogenesis in the vasculature is accelerated by changes in the dynamic equilibrium between endogenous tissue plasminogen activator and plasminogen activator inhibitor-1 (PAI-1).
|
296 |
10418858
|
Increased expression of PAI-1, decreased expression of tissue plasminogen activator, or both can lead to decreased fibrinolytic activity and predispose to thrombosis.
|
297 |
10418858
|
Increased concentrations of insulin (and proinsulin) in the plasma increase plasma PAI-1, although the mechanisms of this effect are not known.
|
298 |
10418858
|
There is also evidence that PAI-1 content is increased in atherosclerotic lesions of patients with type 2 diabetes, suggesting that interventions to reduce insulin resistance and improve glycemic control may improve the fibrinolytic response.
|
299 |
10418858
|
Clinical studies in patients with polycystic ovary syndrome (characterized by insulin resistance, hyperinsulinemia, ovarian androgen overproduction, and impaired fibrinolytic capacity) demonstrated that treatment with troglitazone, an insulin-sensitizing agent, can markedly reduce blood levels of PAI-1.

|
In all patients levels of total cholesterol, triglyceride, HDL cholesterol, LDL cholesterol, lipoprotein (a) (Lpa) C reactive protein (CRP), fibrinogen, thrombin/antithrombin III complex (TAT), plasminogen activator inhibitor type 1(PAI-1), tissue plasminogen activator (t-PA) and von Willebrand antigen were measured.

After H. pylori eradication, the levels of CRP and TAT decreased (48+/-0.7 ng/l vs 3.3+/-0.4 ng/l;P << 0.05), (27.7+/-44.7 microg/ml vs 2.1+/-1.4 microg/ml, P << 0.05), respectively.
|

10578022
|
Eradication of H. pylori infection in type 1 diabetic patients modifies some parameters of lipid and haemostasis patterns, (increase of HDL-cholesterol, reduction of Lpa and decrease of CRP and TAT) and so contributes to improvement of cardiovascular risk factors in these patients.

|
Before and after treatment, glycemic control, steady-state plasma glucose and insulin (SSPG and SSPI, respectively), and markers of fibrinolysis (tissue plasminogen activator [tPA] and plasminogen activator inhibitor-1 [PAI-1]) were analyzed in each patient.
|
313 |
10831180
|
Pretreatment plasma PAI-1 in diabetic patients, but not tPA, was well correlated with the severity of retinopathy assessed by the fluorescence technique.
|
314 |
10831180
|
Four weeks of treatment with troglitazone significantly decreased hemoglobin A1c (HbA1c), SSPG, and PAI-1 without an alteration of tPA.
|
315 |
10831180
|
These results suggest that an abnormal fibrinolytic state, especially overproduction of PAI-1, may be a pathogenic factor in the development of diabetic complications such as retinopathy, which may be improved by correction of the insulin resistance with troglitazone.
|
316 |
10831182
|
The obese subjects presented significantly elevated values for insulin (P < .001), tissue-plasminogen activator ([t-PA] P < .001), plasminogen activator inhibitor-1 ([PAI-1] P < .001), and fibrinogen (P < .001) with respect to the control group.
|
317 |
10831182
|
In the obese subjects, insulin, PAI-1, and F1 + 2 were positively correlated with the BMI.
|
318 |
10831182
|
On the other hand, t-PA was correlated with insulin and PAI-1 but not with the BMI.
|

|
Elevated levels of plasminogen activator inhibitor-1 (PAI-1) with and without reduction of tissue plasminogen activator (tPA) in plasma have been frequently found in patients with DM.
|
320 |

|
Our previous studies indicated that glycation enhances low density lipoprotein (LDL)-induced production of PAI-1 and further decreases tPA generation in vascular endothelial cells (ECs).
|
321 |
10845890
|
The present study demonstrated that treatment with antioxidants, butylated hydroxytoluene or vitamin E, blocked native LDL- and glycated LDL-induced changes in PAI-1 and tPA generation in ECs.
|
322 |
10845890
|
Cotreatment with native or glycated HDL inhibited LDL-induced or glycated LDL-induced changes in PAI-1 and tPA generation in ECs.
|
323 |
10845890
|
The effects of antioxidants and HDL on LDL-induced or its glycated LDL-induced changes in the generation of PAI-1 and tPA were also found in cultured human coronary artery ECs.

|
We tested the hypothesis that troglitazone, which improves insulin sensitivity and lowers plasma insulin levels in insulin-resistant obese subjects and patients with type 2 diabetes, would also lower circulating PAI-1 antigen concentrations and activity.
|
325 |
10871202
|
We assessed insulin sensitivity (5-h, 80 mU x m(-2) x min(-1) hyperinsulinemic-euglycemic clamp) and measured plasma PAI-1 antigen and activities and tissue plasminogen activator (tPA) in 14 patients with type 2 diabetes and 20 normal control subjects (10 lean, 10 obese) before and after 3 months of treatment with troglitazone (600 mg/day).
|
326 |
10871202
|
The extent of the reduction in plasma PAI-1 antigen concentrations in the diabetic patients after troglitazone correlated with the reductions in fasting plasma insulin (r = 0.60, P < 0.05), nonesterified fatty acid (r = 0.63, P < 0.02), and glucose concentrations (r = 0.64, P < 0.02) but not with the improvement in glucose disposal rates during the glucose clamps.
|
327 |
10871202
|
Three nonresponders to troglitazone with respect to effects on insulin sensitivity and fasting glucose and insulin levels also had no reduction in circulating PAI-1.

|
Since little is known about the evaluation of markers of haemostatic and fibrinolytic systems in other adrenal disorders, we studied plasminogen activator inhibitor (PAI-1), tissue-plasminogen activator (t-PA), fibrinogen and von Willebrand factor antigen (vWF-Ag) levels in 11 patients with Cushing's syndrome and in 12 patients with adrenal incidentaloma.
|
329 |
10961361
|
In patients with Cushing's syndrome mean PAI-1, t-PA and vWF-Ag levels did not significantly differ from those found in 50 age- and sex-matched controls, while mean fibrinogen levels were significantly higher in patients (337.0+/-39.1 mg/dl) than in normal subjects (278.9+/-8.4 mg/dl).
|
330 |
10961361
|
Patients with adrenal incidentaloma showed PAI-1, t-PA and vWF-Ag mean levels superimposable to those in controls, while fibrinogen (319.7+/-27.9 mg/dl) was slightly, although not significantly, higher than in normals.

|
Experimental and clinical research supports a direct link between activation of the renin-angiotensin system and production of plasminogen activator inhibitor-1 (PAI-1), the primary physiologic inhibitor of tissue plasminogen activator.
|
333 |
10997795
|
Several studies have reported higher PAI-1 levels in individuals carrying the deletion (D) allele of the angiotensin-converting enzyme (ACE) gene.
|
334 |
10997795
|
We investigated the association between ACE genotypes and plasma PAI-1 levels in a family study of 577 women and 428 men from four US communities.
|
335 |
10997795
|
We found no associations between ACE I/D genotypes and plasma PAI-1 antigen concentrations in a subset of participants without major CHD risk factors (hypertension, hypercholesterolemia, overweight, smoking, diabetes) or in a small sample of African-Americans.
|
336 |
10997795
|
Our findings suggest that the ACE insertion/deletion polymorphism has relatively little, if any, influence on circulating PAI-1 levels in the population at large.

Plasma insulin, leptin, and soluble TNF receptors levels in relation to obesity-related atherogenic and thrombogenic cardiovascular disease risk factors among men.
|
342 |
11472752
|
Plasma leptin and tumor necrosis factor-alpha (TNF-alpha), two adipocyte products, are also proposed to be associated with the development of CVD risk.
|
343 |
11472752
|
The purpose of this study is to evaluate the association of plasma leptin, soluble TNF receptors (sTNF-R), and insulin levels as possible mediators of the effect of obesity on atherogenic and thrombogenic CVD risk factors among men.
|
344 |
11472752
|
We measured plasma insulin and leptin levels by radioimmunoassay and sTNF-R levels by ELISA.
|
345 |
11472752
|
Men in the highest quintile of body mass index (BMI, mean=30.5 kg/m(2)) were less physically active and had a more adverse cardiovascular lipid and homeostatic profile, as indicated by levels of insulin, triglyceride (TG), tissue plasminogen activator (t-PA) antigen levels, and apolipoprotein A1 (Apo-A1).
|
346 |
11472752
|
In a multivariate regression model controlling for age, smoking, alcohol intake, physical activity and diet, BMI was inversely associated with HDL-cholesterol (HDL-C) and Apo-A1 and positively associated with TG, Apo-B and t-PA antigen levels.
|
347 |
11472752
|
The associations between BMI and these CVD risk factors were only slightly changed after adjusting for leptin and/or sTNF-R; but were substantially attenuated after controlling for insulin levels.
|
348 |
11472752
|
These data suggest that the association between obesity and biological predictors of CVD may be mediated through changes in plasma insulin, rather than leptin or sTNF-R levels.

Adhesion molecules [E-selectin, intracellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule-1], von Willebrand factor, total nitric oxide (NO), endothelin-1, tissue plasminogen activator, and plasminogen activator inhibitor-1 were measured in 43 type 2 diabetic subjects with hemoglobin A1c of 9.0% or more at baseline (compared with 21 healthy controls) who after 20 wk had been randomized to either improved (IC) or usual (UC) glycemic control.
|
357 |
11701727
|
Body mass index in the diabetic patients was the only independent predictor of E-selectin (P = 0.007), ICAM-1 (P = 0.01), and NO (P = 0.008) concentrations, but not vascular cell adhesion molecule-1, plasminogen activator inhibitor-1, or tissue plasminogen activator (all P > 0.05).
|
358 |
11701727
|
Type 2 diabetic patients with a body mass index of 28 kg/m2 or less had concentrations of E-selectin, ICAM-1, endothelin-1, and NO similar to those in healthy controls.

Previous studies by our group indicated that nonenzymatically glycated low density lipoprotein (LDL) increased plasminogen activator inhibitor-1 (PAI-1) production and decreased the generation of tissue plasminogen activator (tPA) from cultured human umbilical vein endothelial cells (HUVEC).
|
363 |
11788661
|
The present study demonstrates that plasma levels of PAI-1 or PAI-1/tPA were significantly increased in patients with type 1 (n = 10) and type 2 DM (n = 14) compared with those in healthy controls (n = 10; P < 0.05 or 0.01).
|
364 |
11788661
|
LDL from patients with type 1 or type 2 DM, and very low density lipoprotein (VLDL) from patients with type 2 DM induced significantly greater increases in the release of PAI-1 and more profound reduction in tPA generation from HUVEC compared with corresponding lipoproteins from healthy controls (P < 0.05 or 0.01).
|
365 |
11788661
|
HDL from diabetic patients did not significantly alter the generation of PAI-1 or tPA from endothelial cells (EC) compared with HDL from controls.
|
366 |
11788661
|
Comparable effects of lipoproteins from DM patients on the generation of PAI-1 and tPA were found in human coronary artery EC.
|
367 |
11788661
|
The results of the present study suggest that LDL and VLDL from patients with DM reduce the generation of tPA and increase PAI-1 production through the activation of the PAI-1 promoter in vascular EC.

Recently, annexin II, a member of annexin family proteins, has been found to work as co-receptor on endothelial cells for plasminogen and tissue plasminogen activator, facilitating plasmin generation on the surface of vascular endothelium.
|

|
In this review, we overviewed the effect of glucose and insulin on plasmin generation in endothelial cells and its potential modulation by recombinant annexin II (rAN II) based on our data.

Imbalance of plasminogen activator inhibitor-I/ tissue plasminogen activator and tissue factor/tissue factor pathway inhibitor in young Japanese men with myocardial infarction.
|
375 |
11816707
|
To evaluate the association between haemostatic parameters and increased risk of myocardial infarction (MI) at a young age, we measured fibrinogen, factor VII, antithrombin III, protein C, protein S, tissue factor (TF), free form tissue factor pathway inhibitor (TFPI), plasminogen, alpha2-antiplasmin, tissue plasminogen activator (tPA), plasminogen activator inhibitor-I (PAI-I), and lipoprotein (a) in 140 young men with MI before age 45 and 150 age-matched healthy men.
|
376 |
11816707
|
TF, TF/TFPI ratio, PAI-I, PAI-I/tPA ratio, plasminogen, and lipoprotein (a) in young MI patients were all significantly higher than controls, while TFPI, antithrombin II, and tPA were significantly lower (P <0.001 of each).
|
377 |
11816707
|
Significant determinants of MI risk were PAI-I/tPA ratio (R2 = 0.300, P <0.001), TF/TFPI ratio (R2 = 0.049, P <0.001), antithrombin III (R2 = 0.034, P <0.001), hyperlipidaemia (R2 = 0.019, P = 0.004), diabetes (R2 = 0.014, P = 0.015), lipoprotein (a) (R2 = 0.012, P = 0.023), alpha2-antiplasmin (R2= 0.014, P = 0.012), and protein C (R2= 0.012, P = 0.018).
|
378 |
11816707
|
We conclude that the imbalances of PAI-I/tPA and TF/TFPI are significantly associated with MI at a young age, perhaps mediated via impaired fibrinolytic activity.

Increased fibrinogen, von Willebrand factor and tissue plasminogen activator levels in insulin resistant South Asian patients with ischaemic stroke.
|
385 |
12052485
|
Stroke patients showed elevated levels of fibrinogen (3.78 vs. 3.41 mg/dl, P=0.02), von Willebrand factor (1.78 vs. 1.50 IU/ml, P=0.006) and tissue plasminogen activator (12.8 vs. 11.3 ng/ml, P=0.04), but the differences did not persist after adjustment for glucose, triglycerides, HDL, WHR, and BMI.
|
386 |
12052485
|
Higher levels of fibrinogen, von Willebrand factor and t-PA in South Asian stroke patients disappeared after adjustment for features of insulin resistance syndrome but persisted after adjustment for presence of diabetes, confirming that these changes are essentially dependant on features of insulin resistance syndrome.

There is increasing evidence that elevated plasma levels of hemostatic factors [fibrinogen, factor VII, von Willebrand factor, fibrin D-dimer, and tissue plasminogen activator (t-PA) antigen] are independently linked to risk for coronary heart disease (CHD).
|
391 |
12107238
|
Factor VIIc was determined by a clotting assay; fibrinogen was determined by nephelometry; and t-PA, D-dimer, and von Willebrand factor antigens were measured by ELISA techniques.
|
392 |
12107238
|
Of these hemostatic markers, only t-PA concentration was significantly (P = 0.013) elevated in women with PCOS relative to controls. t-PA correlated with BMI in both PCOS and controls (r = 0.428, P < 0.1; and r = 0.686, P < 0.01) and inversely with the insulin sensitivity index (r = -0.590, P < 0.05; and r = -0.620, P < 0.05, respectively).
|
393 |
12107238
|
After further adjustment for BMI and insulin sensitivity, there remained a significant difference in t-PA between cases and controls (P = 0.017).
|
394 |

The existing experimental evidence suggests that annexin II in its tetrameric form is the main physiological receptor for plasminogen on the extracellular surface of endothelial cells.
|
397 |
12208147
|
We hypothesize that glycation of endothelial membrane annexin II impairs the appropriate formation of the plasminogen/tissue plasminogen activator/annexin II complex, disrupting a key regulatory mechanism in fibrinolytic vigilance.
|
398 |
12208147
|
Binding of plasminogen to annexin II is inhibited by Lp (a) and binding of tissue plasminogen activator to annexin II is blocked by homocysteine.

We estimated the levels of t-PA and PAI-1 in platelet-poor plasma of 42 patients with AMI on admission, using the enzyme-linked immunosorbant assay.
|
413 |
12214153
|
Although not statistically significant, patients having an AMI in the morning hours had the highest t-PA:PAI-1 ratio.
|

Both angiotensin-converting enzyme (ACE) inhibitors and AT-1 receptor antagonists reduce the effects of angiotensin II, however they may have different clinical effects.
|
416 |
12437489
|
This is because the ACE inhibitors, but not the AT-1 receptor antagonists, increase the levels of substance P, bradykinin and tissue plasminogen activator.
|
417 |
12437489
|
The AT-1 receptor antagonists, but not the ACE inhibitors, are capable of inhibiting the effects of angiotensin II produced by enzymes other than ACE.

Assessments included tissue-Plasminogen Activator (t-PA), Plasminogen Activator Inhibitor-1 antigen (PAI-1 Ag), Plasminogen Activator Inhibitor-1 activity (PAI-1 Act), Plasminogen (Pl), Fibrin peptide A (FPA), Fibrinogen (Fr), and the ankle/brachial pressure index (ABI).
|

12540958
|
We observed a significant difference between diabetic patients and controls as regards tPA (11.8 +/- 5.4 vs. 6.6 +/- 3.0 ng/ml; p <0.05) and PAI-1 Act (17.8 +/- 9.2 vs. 11.7 +/- 6.6 ng/dl; p <0.005).
|
420 |
12540958
|
After 4 years 13 diabetic patients became vasculopathic and, at baseline, had significantly lower tPA (8.9 +/- 4.8 vs. 12.5 +/- 5.3; p <0.011), and higher PAI-1 Ag (50.8 +/- 22.2 vs. 32 +/- 22.2; p <0.006), and PAI-1 Act values (24.1 +/- 9.5 vs. 16.1 +/- 8.4; p <0.014), compared with 50 diabetic patients who did not develop PAD after 4 years.
|
421 |
12540958
|
These data show that the physiological equilibrium which exists between t-PA and PAI-1 moves towards higher levels in our diabetic patients compared with controls, at baseline, whereas diabetic patients who developed PAD showed a shift towards an antifibrinolytic pathway with diminished t-PA, increased PAI-1 Ag and PAI-1 Act and consequently procoagulant activity.

One such cluster included genes that promote the degradation of fibrin clots such as tissue plasminogen activator (t-PA), connective tissue activation peptide III (CTAP III) and tetranectin.
|
424 |
12611918
|
The fibrinolytic activity and protein levels of tetranectin, and t-PA and its endogenous inhibitor PAI-1, were subsequently shown to change significantly in both skeletal muscle and serum in response to exercise training.

Other accompanying abnormalities may include elevated levels of leptin, TNFalpha, tissue plasminogen activator, plasminogen activator inhibitor-1, and testosterone.
|
427 |
12871271
|
Additionally, elevated levels of plasminogen activator inhibitor-1, factor (F)VII, FXII, fibrinogen and tissue plasminogen activator occur with insulin resistance to create an atherothrombotic risk cluster.

Plasma insulin concentrations were kept constant at approximately 35 pmol/l by intravenous somatostatin-insulin infusions and there was no significant change in plasma glucose levels during any of the study protocols.
|
429 |
12958610
|
While tissue plasminogen activator (tPA) and adipsin, an adipocyte derived protease, were unaffected by LIP, changes in soluble vascular cell adhesion molecule-1 (sVCAM-1) were significantly correlated (p = 0.02) with those seen for PAI-1.
|
430 |
12958610
|
This suggests that hyperlipidemia independent of insulin and plasma glucose levels stimulates vascular tissue and in turn might induce an increase in plasma PAI-1.

|
However, which of the two plasminogen activators (PAs) present in renal tissue, tissue plasminogen activator (tPA) or urokinase-type plasminogen activator (uPA), is responsible for plasmin generation and those factors that modulate the activity of this system remain unclear.
|
432 |
14530509
|
This study utilized mesangial cells isolated from mice with gene deletions for tPA, uPA, and plasminogen activator inhibitor 1 (PAI-1) to further delineate the role of the PA/plasminogen/plasmin system in ECM accumulation.
|
433 |
14530509
|
In contrast, ECM degradation by tPA-null mesangial cells was markedly reduced (-78 +/- 1%, n = 12, P < 0.05) compared with controls, whereas tPA/uPA double-null mesangial cells degraded virtually no ECM.
|
434 |
14530509
|
Previous studies from this laboratory have established that transforming growth factor-beta1 (TGFbeta1) inhibits ECM degradation by cultured mesangial cells by increasing the production of PAI-1, the major physiological PA inhibitor.
|
435 |
14530509
|
Taken together, these results document the importance of tPA versus uPA in renal plasmin production and indicate that in contrast to elevated glucose, glycated albumin may contribute to ECM accumulation in diabetic nephropathy.

|
We evaluated the association of hemostatic factors with insulin resistance in relation to reproductive hormones including FSH, estradiol, testosterone, and SHBG.
|
437 |
14557472
|
We measured the hemostatic factors, fibrinogen, factor VIIc, tissue plasminogen activator (t-PA), and plasminogen activator inhibitor type 1 (PAI-1), as well as glucose and insulin to calculate insulin resistance.
|
438 |
14557472
|
After adjustment for body mass index, site, and ethnicity, SHBG was correlated with PAI-1 (partial r = -0.30) and t-PA (partial r = -0.12).
|
439 |
14557472
|
Although testosterone was associated with t-PA (partial r = 0.13) and PAI-1 (partial r = 0.07), free androgen index was strongly correlated with t-PA (partial r = 0.18) and PAI-1 (partial r = 0.26).
|
440 |
14557472
|
SHBG modified the association of hemostatic factors with insulin resistance.
|
441 |
14557472
|
Women with greater insulin resistance had lower SHBG and higher PAI-1.
|
442 |

|
We evaluated cross-sectionally the association between periodontal disease and C-reactive protein (CRP), fibrinogen, factor VII, tissue plasminogen activator (t-PA), LDL-C, von Willebrand factor, and soluble tumor necrosis factor receptors 1 and 2.
|
446 |
14742654
|
In multivariate regression models controlling for age, cigarette smoking, alcohol intake, physical activity, and aspirin intake, self-reported periodontal disease was associated with significantly higher levels of CRP (30% higher among periodontal cases compared with non-cases), t-PA (11% higher), and LDL-C (11% higher).

Cerebral ischemia/reperfusion in normal and diabetic rats was accompanied by increased expression of tissue plasminogen activator (t-PA), urokinase plasminogen activator (u-PA), plasminogen activator inhibitor 1 (PAI-1) and neuroserpin (NSP) mRNA after reperfusion.
|
449 |
15223382
|
Most importantly, the expression of NSP mRNA, but not t-PA, u-PA and PAI-1 mRNA, was reduced to undetectable levels at 11 and 23 h after reperfusion in diabetic rats as compared with normal rats.
|
450 |
15223382
|
Although activity of PA (t-PA and u-PA) and the ratio of PA/PAI were increased at 5 h after reperfusion in both ischemic brains of diabetic and normal rats, the levels in diabetic rats were lower than that in normal rats.

|
Studies in human adipocytes indicate that PAI-1 synthesis is upregulated by insulin, glucocorticoids, angiotensin II, some fatty acids and, most potently, by cytokines such as tumour necrosis factor-alpha and transforming growth factor-beta, whereas catecholamines reduce PAI-1 production.

Increased plasminogen activator inhibitor-1 (PAI-1) and decreased tissue-plasminogen activator (t-PA) activities lead to impaired fibrinolysis, which is critical for cardiovascular disease.
|
464 |
15901895
|
Plasma PAI-1, t-PA, and glucose as well as serum C-peptide, insulin, total cholesterol, triglyceride, and HDL and LDL cholesterol levels were measured at 0, 2, 4, and 6 h after the fat load.
|
465 |
15901895
|
The PAI-1 activities decreased significantly during the loading tests (p < 0.0001), whereas the t-PA activities did not change.
|
466 |
15901895
|
We conclude that elevated PAI-1 and diminished t-PA activities, suggestive of suppressed fibrinolysis, are present in our adolescents with type 2 diabetes; adding another risk factor for cardiovascular disease and acute high fat load does not further negatively affect this suppressed fibrinolysis.

Human aortic endothelial cell (HAEC) tPA and PAI-1 production were determined after incubation with LDL (50 to 500 microg/mL protein, 24 h) from three sources: (1) nondiabetic LDL (N-LDL) modified in vitro to form six preparations: native, nonmodified (N); glycated (G); minimally oxidized (MO); minimally oxidized and glycated (MOG); heavily oxidized (HO); and heavily oxidized and glycated (HOG); (2) in vivo glycated and relatively nonglycated LDL subfractions from type 1 diabetic patients; (3) LDL from type 1 diabetic patients and matched controls, which was subfractionated using density gradient ultracentrifugation.
|
475 |
16037259
|
Results using in vivo glycated versus nonglycated LDL showed that tPA and PAI-1 release did not differ between subfractions.
|
476 |
16037259
|
Release of tPA averaged 5.11 +/- 0.6 and 5.12 +/- 0.7 ng/mg/24 h, whereas release of PAI-1 averaged 666 +/- 27 ng/mg/24 h and 705 +/- 30 ng/mg/24 h for nonglycated and glycated LDL subfractions, respectively.
|
477 |
16037259

|
TAFI-mediated inhibition of fibrinolysis in DM2 is regulated independently from PAI-1.
|
540 |
21993838
|
PAI-1 is the fast acting and specific inhibitor of tissue plasminogen activator (tPA) and urokinase (uPA), the activators of plasminogen and consequently of fibrinolysis.
|
541 |
21993838
|
These molecules include transforming growth factor β (TGF-β), tumor necrosis factor α (TNF-α), angiotensin II and interleukin 6 (IL-6), all of which up-regulate PAI-1 in various cell types or can be up-regulated by PAI-1.
|
542 |
21993838
|
Thus, PAI-1 plays a critical role in the insulin resistance syndrome, which leads to type 2 diabetes mellitus, and is associated with its side effects such as an increased risk of diabetic nephropathy, atherosclerotic cardiovascular disease and others.

Upregulation of matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) in diabetes appears to play a role in vascular complications of diabetes.
|
544 |
22045867
|
We hypothesised that inhibition of MMP-2 and MMP-9 by minocycline can be potentiated by aspirin through inhibition of cyclooxygenase-2 and tissue plasminogen activator, resulting in amelioration of clinical cerebral ischaemia in diabetes.
|
545 |
22045867
|
Moreover, this therapy was associated with significantly lower mortality and reduction in MMP-2 and MMP-9 levels.
|
546 |
22045867
|
Our data indicate that combination of aspirin and minocycline therapy protects from the consequences of cerebral ischaemia in animal models of diabetes and is associated with inhibition of MMP-2 and MMP-9.
