Fifty-seven adult nondiabetic subjects (17 lean 40 obese) were enrolled a 3-month supervised exercise. expressions measured PBMCs subcutaneous adipose tissue before after Circulating plasma levels also investigated. There was significant increase compared lean. PBMCs, however, while mRNA...
The hepatokine fetuin-A is linked to obesity and type 2 diabetes, but its presence expression in adipose tissue remain unclear. In this study, we aimed assess the circulating levels of subcutaneous (SAT) from diabetic non-diabetic obese subjects their modulation by exercise.SAT blood were obtained adults (diabetic, n=118 non-diabetic, n=166) before after a 3-month exercise program n=40 n=36, respectively). Plasma was assayed using ELISA. SAT, peripheral mononuclear cells (PBMCs) cell lines...
Heat shock protein 60 (HSP60) is a key in the crosstalk between cellular stress and inflammation. However, status of HSP60 diabetes obesity unclear. In present study, we investigated adipose tissue obese adults with without changes its expression response to supervised 3-month physical exercise program. Subcutaneous (SAT) blood samples were collected from (n=138 n=92, respectively, at baseline; n=43 for both groups after 3 months exercise). Conventional RT-PCR, immunohistochemistry,...
Abstract Heat shock response (HSR) is an essential host-defense mechanism that dysregulated in obesity-induced insulin resistance and type 2 diabetes (T2D). Our recent data demonstrated DNAJB3 was downregulated obese human subjects showed negative correlation with inflammatory markers. Nevertheless, expression pattern diabetic its mode of action are not yet known. In this study, we reduction transcript protein levels PBMC subcutaneous adipose tissue T2D compared to non-diabetic subjects....
Background . The impact of gender difference on the association between metabolic stress and cardiovascular disease (CVD) remains unclear. We have investigated, for first time, effect oxidative inflammatory responses assessed their correlation with classical cardiometabolites in Arab population.

Epoxide hydrolase 2 (EPHX2) is an emerging therapeutic target in several immunometabolic disorders. EPHX2 metabolizes anti-inflammatory epoxyeicosatrienoic acids into pro-inflammatory diols. The contribution of activity to human obesity remains unexplored. We compared the expression between lean and obese humans (n = 20 each) subcutaneous adipose tissue (SAT) peripheral blood mononuclear cells (PBMCs) using RT-PCR, Western Blot analysis, immunohistochemistry, confocal microscopy before after...

Normal-weight (n = 37) overweight adults without T2D 98 n 107, respectively) were enrolled study. A subset subjects 39 for each...
Background: Angiopoietin-like protein 8 (ANGPTL8) is known to regulate lipid metabolism and inflammation. It interacts with ANGPTL3 ANGPTL4 lipoprotein lipase (LPL) activity IKK modulate NF-κB activity. Further, a single nucleotide polymorphism (SNP) leading the ANGPTL8 R59W variant associates reduced low-density lipoprotein/high-density (LDL/HDL) increased fasting blood glucose (FBG) in Hispanic Arab individuals, respectively.
