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-...

Peroxisome proliferator-activated receptor-gamma (PPAR-gamma) has currently been considered as molecular target for the treatment of human metabolic disorders. Experimental data from in vitro cultures, animal models, and clinical trials have shown that PPAR-gamma ligand activation regulates differentiation and induces cell growth arrest and apoptosis in a variety of cancer types. Tumor angiogen...

More than 10 million people worldwide are living with Parkinson’s disease (PD). The ages of people who have Parkinson are variable, usually between 50 and 80 years, the average of them is 55 years old. The symptoms of PD are progressive, and within 10 to 20. It happens when dopaminergic neurons were being degenerate. Peripheral and central inflammatory and oxidative stress pathways play a...

Peroxisome proliferator-activated receptor-gamma (PPAR-gamma) is highly expressed in lipid-accumulating macrophages of the coronary artery. In light of this, the wide-spread clinical use of thiazolidinediones (TZDs) in the treatment of type II diabetes raises concerns about the role of PPAR-gamma in macrophage function and disease progression. To define the role of PPAR-gamma in macrophage biol...

The peroxisome proliferator-activated receptor gamma (PPAR gamma) is a member of the nuclear receptor family that forms heterodimers with retinoid X receptor. These heterodimers bind to DNA and activate the transcription of target genes. Here, we report that the PPAR gamma receptor protein is expressed in primary myeloid and lymphoid leukemias and in lymphoma and myeloma cell lines. In this stu...

BACKGROUND Peroxisome proliferator-activated receptor-(gamma) (PPAR(gamma)) is expressed in human platelets although in the absence of genomic regulation in these cells, its functions are unclear. OBJECTIVE In the present study, we aimed to demonstrate the ability of PPAR(gamma) ligands to modulate collagen-stimulated platelet function and suppress activation of the glycoprotein VI (GPVI) sig...

BACKGROUND We have previously demonstrated a glomerulo-tubular 'crosstalk' operating in the pathogenesis of tubulointerstitial injury in IgA nephropathy (IgAN). The present study aims to explore any possible beneficial effect of a peroxisome proliferator-activated receptor-gamma (PPAR-gamma) agonist in alleviating the tubulointerstitial inflammation in IgAN. METHODS Human proximal tubular epi...

BACKGROUND AND PURPOSE Although their primary mechanism of action is blood pressure lowering, emerging data suggest that select angiotensin receptor blockers (ARBs), which partially activate the peroxisome proliferator-activated receptor gamma (PPAR-gamma), may effectively treat insulin resistance and dyslipidemia without the toxicity sometimes associated with full PPAR-gamma agonists. Since up...

ABsTRAcT Peroxisome proliferator-activated receptor-gamma (PPAR-γ), a nuclear receptor, is highly expressed in the colonic epithelium in contrast to its impaired expression in the patients with ulcerative ...

Peroxisome proliferator-activated receptor-gamma (PPAR-gamma), an essential transcriptional mediator of adipogenesis, lipid metabolism, insulin sensitivity, and glucose homeostasis, is increasingly recognized as a key player in inflammatory cells and in cardiovascular diseases (CVD) such as hypertension, cardiac hypertrophy, congestive heart failure, and atherosclerosis. PPAR-gamma agonists, th...
