Peroxisome proliferator-activated receptor-gamma (PPAR-gamma) is a ligand-dependent transcription factor that plays an important role in the regulation of insulin sensitivity and lipid metabolism. Evidence shows that PPAR-gamma agonists also ameliorate renal fibrotic lesions in both diabetic nephropathy and nondiabetic chronic kidney disease. However, little is known about the mechanism underly...

background leptin and adiponectin are two hormones, which are released from adipocytes in order to control energy expenditure. both hormones are also involved in glucose homeostasis through control of insulin secretion from pancreatic islets. since pdx1, pparγ, and foxm1 play important roles in islets function, it is essential to understand how these genes are regulated in the islets of langerh...

Peroxisome proliferator-activated receptors (PPARs) are a group of ligand-dependent nuclear receptors responsible for gene expression regulation and function as transcriptional regulators of adipogenic differentiation and lipid metabolism. Members of PPAR family, especially PPAR gamma, are predominantly expressed in adipose tissue and have been demonstrated as important regulators of stem cell ...

Peroxisome proliferator-activated receptors (PPAR) are nuclear receptors acting as transcription factors on numerous target genes after heterodimerization with the retinoid X receptor. PPAR-alpha and PPAR-gamma may be activated by different agonists, although the endogenous ligands are unknown. Although PPAR-alpha is mainly involved in fatty acid oxidation and expressed in liver, kidney, and sk...

The main etiologic factor for chronic bronchitis is cigarette smoke. Exposure to cigarette smoke is reported to induce goblet cell hyperplasia and mucus production. Mucin synthesis in airways has been reported to be regulated by the EGFR system. Peroxisome proliferator-activated receptor-gamma (PPAR-gamma) is a member of the ligand-activated nuclear receptor superfamily. PPAR-gamma is implicate...

BACKGROUND Peroxisome proliferator-activated receptors are nuclear receptors highly expressed in intestinal epithelial cells (IEC) and immune cells within the gut mucosa and are implicated in modulating inflammation and immune responses. The objective of this study was to investigate the effect of targeted deletion of PPAR gamma in IEC on progression of experimental inflammatory bowel disease (...

The peroxisome proliferator-activated receptor superfamily (PPARs) comprises a class of nuclear receptors with significant effects in regulating multiple cellular pathways. Much research and clinical interest has surrounded the PPAR-gamma isoform because of its key role in the transcriptional regulation of metabolic pathways and the efficacy of thiazolidinediones, the most clinically used PPAR-...

The nuclear hormone receptor PPAR gamma promotes adipogenesis and macrophage differentiation and is a primary pharmacological target in the treatment of type II diabetes. Here, we show that PPAR gamma gene knockout results in two independent lethal phases. Initially, PPAR gamma deficiency interferes with terminal differentiation of the trophoblast and placental vascularization, leading to sever...

Renal endothelial damage is pivotal in the initiation and progression of renal disease. Damaged renal endothelium may be regenerated through proliferation of local endothelium and circulation-derived endothelial progenitor cells. Activation of the PPAR-gamma-receptors present on endothelial cells affects their cellular behavior. Proliferation, apoptosis, migration, and angiogenesis by endotheli...

Peroxisomal proliferator-activated receptors (PPARs) belong to a nuclear receptor superfamily of ligand-activated transcription factors. The PPAR-gamma isoform is expressed in human T lymphocytes, and oral administration of PPAR-gamma agonists ameliorates the clinical course and histopathological features in experimental autoimmune encephalomyelitis, an animal model for multiple sclerosis, sugg...
