Plasma matrix metalloproteinase (MMP)-9 is a predictor of cardiovascular mortality, and MMP-9 polymorphisms affect plasma MMP-9 levels. However, no study examined whether MMP-9 haplotypes affect MMP-9 levels in obese adults. We examined whether MMP-9 polymorphisms and haplotypes are associated with obesity, and whether they affect MMP-9 levels in obese subjects.

Obesity is considered a subchronic inflammatory disease with high risk of comorbidity development. Obesity-associated inflammation originates from adipose tissue itself, which secretes a panel of inflammatory chemokines and cytokines. Therefore, we enrolled 23 obese women without comorbidity and evaluated if simvastatin 20 mg/day dose therapy for 6 weeks (n=15) may modulate plasma levels of inflammatory CXCL-10, CCL-2, CXCL-9, CXCL-8, and CCL-5.

Higher homocysteine (Hcy) levels are associated with cardiovascular risk. The aim of the present study was to evaluate the effect of simvastatin treatment on circulating Hcy levels in obese women without hypertension, diabetes or dyslipidaemia; and to determine whether the 677C>T polymorphism located in methylenetetrahydrofolate reductase (NAD(P)H) (MTHFR) gene modulates the effects of this treatment on Hcy and nitrite (as a biomarker of nitric oxide (NO) bioavailability). Twenty-five obese women (body mass index ≥ 30 kg/m(2) ) who had received 20 mg/day simvastatin for 6 weeks were enrolled in the study.

Statins exert cholesterol-independent beneficial effects on multiple targets including the cardiovascular system, in addition to modulating matrix metalloproteinases (MMPs) expression. The purpose of this study was to assess the effects of simvastatin treatment in obese women without comorbidities. We recruited 33 obese women that received placebo or simvastatin at 20 mg/day for 45 days.

The adipose tissue expansion is accompanied by remodeling of extracellular matrix performed by matrix metalloproteinases (MMPs). Higher plasma and tissue MMP-9 levels are found in obese; therefore, we evaluated if the functional C(-1562)T polymorphism (rs3918242) located in promoter region of the MMP-9 gene is associated with obesity in women. We studied 112 lean and 114 obese women.

Objectives: To compare the plasma concentrations of matrix metalloproteinase (MMP)-9, tissue inhibitor of MMP (TIMP)-1, MMP-8, and myeloperoxidase (MPO) for obese and lean women.

Design And Methods: We recruited 30 lean and 36 obese women without comorbidities. The MMP-9, TIMP-1, and MMP-8 levels were measured using enzyme-linked immunosorbent assay (ELISA).

GPR91 is an orphan G-protein-coupled receptor (GPCR) that has been characterized as a receptor for succinate, a citric acid cycle intermediate, in several tissues. In the heart, the role of succinate is unknown. We now report that rat ventricular cardiomyocytes express GPR91.
