The mRNA levels for MMP-1 and MMP-3 decreased with age in STZ-induced diabetes.
|
2 |
7533311
|
At 24 weeks after STZ injection, mRNA levels for MMP-1 and MMP-3 fell to 40% (p < 0.01) and 20% (p < 0.01), respectively, in the glomeruli of diabetic rats when compared with control rats.
|

7533311
|
In contrast, mRNA levels for TIMP-1 increased significantly with age in the diabetic glomeruli and reached an 8-fold (p < 0.01) increased at 24 weeks after STZ injection. mRNA levels for MMP-2 were not altered in glomeruli from diabetic and control rats throughout the experimental period, whereas those for MMP-9 were not detected in glomeruli from either group of rats.

|
Insulin treatment partially ameliorated the decrease in mRNA levels for MMP-1 and MMP-3 and the increase in those for TIMP-1 in the glomeruli of diabetic rats.
|

|
These data indicate that abnormal gene regulation of MMPs and TIMP-1 in the glomeruli of diabetic rats may contribute to the progression of glomerular lesions and that hyperglycemia or insulin deficiency may be associated with abnormal MMPs and TIMP-1 gene regulation.

At 24 wk, mRNA levels for MMP-1 and MMP-3 fell to 40% (P < 0.01) and 20% (P < 0.01), respectively, in the glomeruli of diabetic rats compared with levels in controls.
|
18 |
7703388
|
In contrast, mRNA levels for TIMP-1 and TIMP-2 increased significantly at 24 wk after streptozotocin injection (TIMP-1: 8.0-fold (P < 0.01) and TIMP-2: 6.4-fold (P < 0.01)).

Selective effects on activator protein-1 expression may explain the quantitative difference in insulin and phorbol ester action.
|

10373474
|
To identify the cis-acting elements that mediate the stimulatory effect of insulin on collagenase-1 (matrix metalloproteinase-1) gene transcription a series of collagenase-chloramphenicol acetyltransferase (CAT) fusion genes were transiently transfected into HeLa cells.
|
21 |
10373474
|
The AP-1 motif appears to be a target for insulin signaling because it is sufficient to mediate an effect of insulin on the expression of a heterologous fusion gene, whereas the data suggest that the Ets motif acts to enhance the effect of insulin mediated through the AP-1 motif.
|
22 |
10373474
|
Moreover, phorbol esters were a much more potent inducer of collagenase-CAT gene transcription than insulin, a difference that may be explained by selective effects of insulin and phorbol esters on AP-1 expression.

Since MMP-1 degrades type I collagen, a major type of collagen in atherosclerotic lesions, it is likely that MMP-1 is involved in promoting destabilization of plaques.

Up-regulation of matrix metalloproteinase-1 expression in U937 cells by low-density lipoprotein-containing immune complexes requires the activator protein-1 and the Ets motifs in the distal and the proximal promoter regions.
|
53 |
12871225
|
We reported previously that low-density lipoprotein (LDL)-containing immune complexes (LDL-IC) stimulated matrix metalloproteinase-1 (MMP-1) expression in U937 histiocytes through Fc gamma receptor (FcgammaR)-mediated extracellular signal-regulated kinase pathway.
|
54 |
12871225
|
The mutation study further indicated that the activator protein-1 (AP-1) (-3471) or Ets (-3836) motifs in this distal region were essential for the LDL-IC-stimulated MMP-1 expression.
|
55 |
12871225
|
Moreover, although above deletion analysis showed that LDL-IC did not stimulate MMP-1 promoter activity in cells transfected with constructs that contained the proximal AP-1 (-72) and Ets (-88) in the promoter fragments that are 2685-bp or less, the mutations of the -72 AP-1 or the -88 Ets motif in the construct 1 abolished the stimulation of MMP-1 expression by LDL-IC, suggesting that a long promoter sequence is required for the -72 AP-1 and -88 Ets motifs to be involved in the stimulation.

Effects of low-density lipoprotein apheresis on plasma matrix metalloproteinase-9 and serum tissue inhibitor of metalloproteinase-1 levels in diabetic hemodialysis patients with arteriosclerosis obliterans.
|
78 |
12918586
|
The purpose of this study was to determine whether LDL pheresis alters levels of plasma matrix metalloproteinase-9 (MMP-9) and serum tissue inhibitor of matrix metalloproteinase-1 (TIMP-1).
|
79 |
12918586
|
MMP-9 and TIMP-1 were measured in 30 healthy control subjects (Group A), 20 type 2 diabetic hemodialysis patients without obvious arteriosclerosis obliterans (ASO) (Group B), and 20 type 2 diabetic hemodialysis patients with ASO (Group C).
|
80 |
12918586
|
Twelve Group C patients underwent LDL apheresis once weekly for 10 weeks, and changes in plasma MMP-9 and serum TIMP-1 levels because of LDL apheresis were measured.
|
81 |
12918586
|
Plasma MMP-9 and serum TIMP-1 levels decreased significantly after LDL apheresis (p < 0.05).
|
82 |
12918586
|
The data suggested that MMP-9 and TIMP-1 are associated with ASO and that LDL apheresis is effective in reducing plasma MMP-9 and TIMP-1 levels in type 2 diabetic hemodialysis patients with ASO.

Results show that troglitazone, but not pioglitazone and rosiglitazone, stimulated MMP-1 secretion and mRNA expression in both human umbilical vein and aortic endothelial cells, but had no effect on TIMP-1 and TIMP-2 secretion.
|
85 |
12921974

12921974
|
In summary, the present study demonstrates that insulin sensitizers have different effects on MMP-1 expression, and troglitazone stimulates MMP-1 mRNA expression and protein synthesis at the pharmacological concentrations, but inhibits MMP-1 synthesis at higher doses.

Altered local gene expression of humoral factors (eg, transforming growth factor-b, connective tissue growth factor, and platelet-derived growth factor) can lead to increased production of ECM components (eg, fibronectin and collagen IV) or decreased degradation through matrix metalloproteinases (eg, MMP-1, MMP-2).

Sodium lactate increases LPS-stimulated MMP and cytokine expression in U937 histiocytes by enhancing AP-1 and NF-kappaB transcriptional activities.
|
102 |
15941782
|
In the present study, we demonstrated that preexposure of U937 macrophage-like cells to sodium lactate increased LPS-stimulated matrix metalloproteinase (MMP)-1, IL-1beta, and IL-6 secretion.
|
103 |
15941782
|
Augmentation of LPS-stimulated MMP-1 secretion was diminished when sodium lactate was replaced by lactic acid that reduced pH in the culture medium.
|
104 |
15941782
|
Furthermore, quantitative real-time PCR indicated that the increased secretion of MMP-1, IL-1beta, and IL-6 was due to increased mRNA expression.

|
To explore the underlying signaling mechanism, blocking studies using specific inhibitors for NF-kappaB and MAPK cascades were performed.
|
106 |

Results showed that blocking of either NF-kappaB or MAPK pathways led to the inhibition of MMP-1, IL-1beta, and IL-6 expression stimulated by sodium lactate, LPS, or both.
|
107 |

15941782
|
In the present study, we demonstrated that preexposure of U937 macrophage-like cells to sodium lactate increased LPS-stimulated matrix metalloproteinase (MMP)-1, IL-1beta, and IL-6 secretion.
|
111 |
15941782
|
Augmentation of LPS-stimulated MMP-1 secretion was diminished when sodium lactate was replaced by lactic acid that reduced pH in the culture medium.
|
112 |

Peroxisome proliferators activated receptors (PPAR) are ligand-inducible nuclear transacting factors comprising three subtypes, PPARalpha, PPARbeta/delta and PPARgamma, which play a key role in lipids and glucose homeostasis.
|
160 |
19094928
|
All PPAR subtypes have been identified in joint or inflammatory cells and their activation resulted in a transcriptional repression of pro-inflammatory cytokines (IL-1, TNFalpha), early inflammatory genes (NOS(2), COX-2, mPGES-1) or matrix metalloproteases (MMP-1, MMP-13), at least for the gamma subtype.
|
161 |
19094928
|
PPAR full agonists were also shown to stimulate IL-1 receptor antagonist (IL-1Ra) production by cytokine-stimulated articular cells in a subtype-dependent manner.
|
162 |
19094928
|
These anti-inflammatory and anti-catabolic properties were confirmed in animal models of joint diseases where PPAR agonists reduced synovial inflammation while preventing cartilage destruction or inflammatory bone loss, although many effects required much higher doses than needed to restore insulin sensitivity or to lower circulating lipid levels.
|
163 |
19094928
|
However, these promising effects of PPAR full agonists were hampered by their ability to reduce the growth factor-dependent synthesis of extracellular matrix components or to induce chondrocyte apoptosis, by the possible contribution of immunosuppressive properties to their anti-arthritic effects, by the increased adipocyte differentiation secondary to prolonged stimulation of PPARgamma, and by a variable contribution of PPAR subtypes depending on the system.

Postprandial changes over the 4-h period were modestly heritable for WBC (age- and sex-adjusted h(2) = 14 +/- 9%, P = 0.04), but the larger MMP-1 and MMP-9 changes appeared to be independent of additive genetic effects.

To evaluate post-fat load changes in inflammatory markers and genetic influences on these changes, we administered a standardized high-fat meal to 838 related Amish subjects as part of the Heredity and Phenotype Intervention (HAPI) Heart Study and measured a panel of inflammatory markers, including C-reactive protein (CRP), interleukin-1beta (IL-1beta), matrix metalloproteinase-1 and -9 (MMP-1 and MMP-9), and white blood cell (WBC) count, before and 4 h after fat challenge (CRP prechallenge only).
|
228 |
19910936
|
Heritabilities (h(2) +/- s.d.) of basal inflammatory levels ranged from 16 +/- 8% for MMP-9 (P = 0.02) to 90 +/- 7% for MMP-1 (P < 0.0001).
|
229 |
19910936
|
Post-fat load, circulating levels of WBC, MMP-1, and MMP-9 increased by 16, 32, and 43% (all P < 0.0001), with no significant changes in IL-1beta.

Exposure of cells to HG caused significant increases in collagen IV secretion and connective tissue growth factor (CTGF) expression, which was appeased by RLW and RLE at transcriptional levels.
|
314 |
20382513
|
In addition, RLW and RLE but not LW modulated membrane type matrix metalloproteinase-1 (MT-1 MMP) expression, MMP-2 activity and tissue inhibitor of MMP-2 (TIMP-2), which facilitated the degradation of mesangial matrix.
|
315 |
20382513

Furthermore, the augmented expression of CTGF and TIMP-2 in HG-exposed cells was mediated by Akt activation and TGF-beta/Smad signaling through PKCbeta2-responsive signaling pathways.
|
316 |
20382513
|
However, HG-down-regulated MT-1 MMP expression was independent of activation of ERK1/2 and Akt when using their inhibitors of DB98059 (ERK1/2) and LY294002 (Akt) alone or in combination.

|
325 |

|
We reported recently that treatment of diabetic apolipoprotein E-deficient mice with the Toll-like receptor 4 (TLR4) antagonist Rs-LPS, a lipopolysaccharide isolated from Rhodobacter sphaeroides, inhibited atherosclerosis.
|
361 |
23800176
|
Since it is known that Rs-LPS antagonizes TLR4 by targeting TLR4 co-receptor MD-2, this finding indicates that MD-2 is a potential target for the treatment of atherosclerosis.
|
