conclusions in conclusion, the ace and pparg genes do not have a key role in conferring risk for diabetic nephropathy. results ace id genotypes followed hardy-weinberg equilibrium in both cases and controls. but p12a genotypes deviated from hardy-weinberg equilibrium in diabetic controls. chi2 test was applied for the analysis of genotypic distributions in genotypic and dominant models. odds ra...

A recent report indicated that the TR4 nuclear receptor might suppress the prostate cancer (PCa) initiation via modulating the DNA damage/repair system. Knocking-out peroxisome proliferator-activated receptor gamma (PPARG), a nuclear receptor that shares similar ligands/activators with TR4, promoted PCa initiation. Here we found 9% of PCa patients have one allele of PPARG deletion. Results from...

BACKGROUND Genome-wide comparisons of transcription factor binding sites in different species can be used to evaluate evolutionary constraints that shape gene regulatory circuits and to understand how the interaction between transcription factors shapes their binding landscapes over evolution. RESULTS We have compared the PPARG binding landscapes in macrophages to investigate the evolutionary...

The aim of the present study was to investigate the effects of microRNA (miR)-128 inhibition on the targeted activation of peroxisome proliferator-activated receptor gamma (PPARG) and on cardiomyocyte apoptosis induced by myocardial ischemia/reperfusion (I/R) injury. In vitro, the expression of PPARG was detected by reverse transcription-quantitative polymerase chain reaction and western blotti...

Although substantial studies on peroxisome proliferator-activated receptor g (PPARg) have focused on the mechanisms by which PPARg regulates glucose and lipid metabolism, recent reports have suggested that PPARg shows tumorigenic or antitumorigenic effects. The roles and mechanisms of PPARg activation in esophageal cancer remain unclarified. EC109 and TE10 esophageal cancer cells were treated w...

The nuclear receptor PPAR γ is a key regulator of adipogenesis, and alterations of its function are associated with different pathological processes related to metabolic syndrome. We recently identified two PPARG transcripts encoding dominant negative PPAR γ isoforms. The existence of different PPARG variants suggests that alternative splicing is crucial to modulate PPAR γ function, underlying ...

OBJECTIVE The dominant-negative P467L mutation in peroxisome proliferator activated receptor-γ (PPARγ) was identified in insulin-resistant patients with hyperglycemia and lipodystrophy. In contrast, mice carrying the corresponding Pparg-P465L mutation have normal insulin sensitivity, with mild hyperinsulinemia. We hypothesized that murine Pparg-P465L mutation leads to covert insulin resistance,...

Adipocyte differentiation is regulated by at least two major transcription factors, CCAAT/enhancer-binding protein a (C/EBPa) and peroxisome proliferator-activated receptor g (PPARg). Expression of PPARg in fibroblasts converts them to fat-laden cells with an adipocyte-like morphology. Here, we investigate the ability of PPARg to confer insulin-sensitive glucose transport to a variety of murine...

The relationship between peroxisome proliferator-activated receptor γ (PPARG) expression and epigenetic changes occurring in colorectal-cancer pathogenesis is largely unknown. We investigated whether PPARG is epigenetically regulated in colorectal cancer (CRC) progression. PPARG expression was assessed in CRC tissues and paired normal mucosa by western blot and immunohistochemistry and related ...

INTRODUCTION Peroxisome proliferator-activated receptor γ (PPARγ) is a ligand-activated transcription factor of the nuclear receptor superfamily that is involved in lipid and carbohydrate metabolism as well as inflammation; thereby it participates in metabolic diseases including diabetes. Although PPARγ expression has been observed in different tissues of diabetic patients, its level in leukocy...
