The OPG production into the medium decreased dose- and time-dependently after insulin treatment (maximal effect approximately 60% of control) in HVSMCs, whereas TNF-alpha supplement gave rise to increased OPG synthesis in a time- and dose-dependent manner (maximal effect approximately 200% of control).

|
In multivariate analysis, OPG was significantly associated with endothelium-dependent arterial dilation, fasting blood glucose (FBG), hemoglobin A1c (HbA1c), and ultra sensitive C-reactive protein (CRP) at baseline (p<0.01).
|

17023086
|
The absolute changes in OPG showed significant correlation with the changes in endothelium-dependent arterial dilation, FBG, HbA1c, and CRP in diabetic patients during the course of treatment (p<0.01).

The effects of IL-1beta and TNF-alpha on OPG expression were characterised by northern blot and immunoassay.
|

|
The INS-1E cell line and primary pancreatic islets expressed OPG mRNA and secreted OPG protein, both of which were enhanced by IL-1beta and TNF-alpha.

Administration of exogenous OPG prevented both IL-1beta-induced beta cell death and sustained p38 MAPK phosphorylation.

Despite accumulating evidence showing that TNF-related apoptosis inducing ligand (TRAIL) plays a role in vascular biology and that its decoy receptor osteoprotegerin (OPG) is expressed in the vessel wall, modulation of these TNF and TNF-R family members in the early phases of diabetes mellitus has not been investigated.

Among those that showed the greatest changes in regulation were two death receptors, OPG (the gene encoding osteoprotegerin) and Fas, and the death ligand TRAIL.

The aim of this investigation was to evaluate potential age- and gender-related changes in free RANKL and total RANKL (free RANKL+RANKL/osteoprotegerin complexes).

|
TNF-related apoptosisinducing ligand (TRAIL) and osteoprotegerin had the highest level of expression.

|
These skeletal alterations were associated with decreased gene expression (by real-time PCR) of Runx2, osterix, osteocalcin, PTHrP, the PTH type 1 receptor, vascular endothelial growth factor and its receptors, and osteoprotegerin to receptor activator of nuclear factor-kappaB ligand mRNA ratio, and increased peroxisome proliferator-activated receptor-gamma2 mRNA levels.

|
Baseline OPG correlated with fasting insulin, baseline lactate, and low density lipoprotein cholesterol in the diabetic group, and with baseline FFA in the lean group.

We investigated the association of serum OPG with the ankle-brachial index (ABI) and urine albumin:creatinine ratio (UACR), in a bi-ethnic cohort of 1324 African-Americans (mean age 64 years, 71% women) and 1237 non-Hispanic whites (mean age 59 years, 57% women) belonging to hypertensive sibships.

After adjustment for conventional risk factors (age, sex, diabetes, waist circumference, history of smoking, total and HDL cholesterol, hypertension), prior history of myocardial infarction or stroke, and medication (renin-angiotensin-aldosterone system inhibitors, statins, aspirin, estrogen) use, higher OPG levels were significantly associated with lower ABI and higher UACR in African-Americans (P=0.001 and P<0.0001, respectively) and non-Hispanic whites (P=0.017 and P=0.002, respectively); the association remained significant after further adjustment for plasma C-reactive protein (CRP) in both ethnic groups.
|
16 |
19423112
|
In multivariable logistic regression analysis, higher OPG levels were associated with PAD in African-Americans, independent of the covariates listed above (P=0.026); the association remained significant after additional adjustment for plasma CRP (P=0.047).
|
17 |
19423112
|
We conclude that higher OPG levels are associated with lower ABI and higher UACR, independent of conventional risk factors and plasma CRP.

OPG inhibits vascular calcification in vitro and high serum levels have been demonstrated in type 2 diabetes, but serum RANKL and TRAIL and their potential correlation with well-established biomarkers of subclinical vascular inflammation such as high-sensitivity C-reactive protein (hsCRP) and interleukin-6 (IL-6) have not been described.
|

|
After exclusion of diabetes patients with a history of micro- or macrovascular disease, OPG remained significantly higher in those with diabetes, but IL-6 and hsCRP levels were no longer elevated.

|
Markers of bone resorption, activity of tartrate-resistant acid phosphatase (TRAP) and cathepsin K and the number of osteoclasts in the proximal tibia and urinary excretion of deoxypyridinoline, were higher in diabetic rats than control rats. mRNA levels of receptor for activation of NF-kappaB (RANK), c-fos, c-jun, TRAP and cathepsin K were significantly increased in diabetic rats, although RANK ligand, osteoprotegerin, macrophage colony-stimulating factor and c-fms levels were similar to the control value.

|
Only OPG was associated with PAD severity, correlating negatively with ABI (r=-0.26, p=0.03), independent of age, gender, glycaemic status, hsCRP and IL-6.

|
Serum OPG levels correlated significantly with fasting plasma glucose (FPG), HbAlc, HOMA-IR, IL6, and CRP, and inversely correlated with adiponectin after adjusting for age (P<0.05).
|
24 |
20961967
|
The adiponectin concentration was increased (P<0.05), and OPG and CRP levels were decreased in the pioglitazone group (P<0.05), but were unchanged in the metformin group.
|
25 |
20961967
|
In type 2 diabetic patients, pioglitazone decreases OPG levels, and this decrease in OPG levels might be associated with the increase in adiponectin.

Serum OPG levels were associated with obesity, insulin resistance, serum CRP and carotid IMT.

Arterial calcification is the result of a complex interplay between stimulating (bone morphogenetic protein type 2 [BMP-2], RANKL) and inhibitory (matrix Gla protein, BMP-7, osteoprotegerin, fetuin-A, osteopontin) proteins.

Increased HO-1 expression increased the levels of osteonectin, OPG, and BMP-2.
|
30 |
19924377
|
Inhibition of HO activity prevented the increase in osteonectin and potentiated the decrease of osteocalcin and OPG in cells exposed to high glucose levels.

Plasma concentrations of receptor activator of nuclear factor-kappaB ligand (RANKL), osteoprotegerin (OPG), C-terminal telopeptide of type 1 collagen and osteocalcin were measured in type 1 diabetes mellitus patients (n=63) and non-diabetics (n=38) who were also subdivided on the basis of their periodontal status.

Recent studies in mice have demonstrated that insulin signaling in osteoblasts stimulates bone formation and reduces osteoprotegerin production; the latter results in an increase in bone resorption, which then leads to the release of undercarboxylated osteocalcin from bone.
|
33 |
21325461
|
Acute changes in insulin levels, as occur during meals, do not regulate bone turnover, undercarboxylated osteocalcin, or osteoprotegerin levels.

OPG levels were associated in multivariate analysis with age, dialysis vintage, history of cardiovascular disease (CVD) and parathyroid hormone levels.

Our primary goal was to determine whether OPG provided independent prognostic information in patients with chronic HF, and to examine its potential interactions with statin therapy.

The OPG levels between the groups were compared and their correlation with insulin resistance, glycemia and inflammatory markers CRP and TNF-alpha was determined.

The purpose of this study was to determine if changes in body mass index (BMI) and insulin sensitivity influence circulating OPG in healthy subjects.
|
39 |
21087777
|
Both OPG and adiponectin were negatively correlated with body weight, BMI, waist circumference, and fasting plasma insulin while being positively correlated with insulin sensitivity (P < .05).

In contrast to patients with type 2 diabetes mellitus, circulating OPG is lower in obese, but otherwise healthy subjects and is positively correlated with indices of insulin sensitivity.

Osteoprotegerin (OPG) and tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) have recently been reported to be associated with diabetic nephropathy in an in vitro study.

Serum OPG (per SD [1.13 ng mL(-1)] increase in OPG) was associated with an increased risk of a myocardial infarction (1.20; 1.11-1.31), ischemic stroke (1.32; 1.18-1.47), total mortality (1.34; 1.26-1.42), death because of ischemic heart disease, (1.35; 1.18-1.54), stroke (1.44; 1.19-1.75) and non-vascular causes (1.31; 1.22-1.41) after adjustment for age, gender, current smoking, systolic blood pressure, body mass index, high density lipoprotein cholesterol, total cholesterol, creatinine, high sensitivity C-reactive protein (CRP) and diabetes mellitus or HbA1c > 6.1%.

|
Type 2 diabetes mellitus, as a whole, upregulates the levels of OPG, sRANKL, IFN-?, IL-17, and IL-23 and downregulates the production of IL-4 in sites with CP (P <0.05).
