background: peroxisome proliferator activated receptor gamma (pparγ), a member of nuclear receptor superfamily, comprises two isoforms in mouse. these two isoforms are encoded by different mrnas, which are arisen by alternative promoter usage. there are two promoter regions upstream of pparγ gene. a 3 kb fragment, containing several transcription factor binding sites, acts as pparγ1 promoter re...

Peroxisome proliferator-activated receptor-gamma (PPAR)-gamma is a ligand-activated transcriptional factor belonging to steroid receptor superfamily. PPAR-gamma plays a role in both adipocyte differentiation and tumorigenesis. Up to date, PPAR-gamma is expressed in various cancer tissues, and PPAR-gamma ligand induces growth arrest of these cancer cells. In this study, we examined the expressio...

Recent studies have demonstrated that peroxisome proliferator activator-receptors(PPAR)-gamma is expressed in various cancer tissues and its ligand induces growth arrest of these cancer cells through apoptosis. In our study, we investigated the expression of PPAR-alpha, beta and gamma in human bladder tumor (BT) and normal bladder (NB) tissues as well as the effects of PPAR-gamma ligands. Speci...

Peroxisome proliferator-activated receptors (PPARs) are a family of ligand-activated transcription factors that include PPAR-alpha, PPAR-gamma, and PPAR-delta. We hypothesized that PPAR expression in blood vessels could be reduced in hypertension to result in increased vascular growth and reduced apoptosis. We investigated the abundance of PPAR-alpha and PPAR-gamma in aorta and mesenteric arter...

Peroxisome proliferator-activated receptor-gamma (PPAR-gamma) is being studied intensively for its role in carcinogenesis and in mediating the effects of prostate cancer treatment and prevention drugs. Prostate cancers express abundant and higher constitutive levels of PPAR-gamma than do normal prostate cells and are growth inhibited by ligand activation of PPAR-gamma. However, little is known ...

The orphan nuclear receptor, peroxisome proliferator-activated receptor (PPAR) gamma, is implicated in mediating expression of fat-specific genes and in activating the program of adipocyte differentiation. The potential for regulation of PPAR gamma gene expression in vivo is unknown. We cloned a partial mouse PPAR gamma cDNA and developed an RNase protection assay that permits simultaneous quan...

results the results showed that children with a higher weight z-score spend more time in sedentary activities and less time running or involved in active games. scd-1 activity index, arachidonic/linoleic index, and adipocyte volume were significantly higher in children with a weight z-score greater than 0. the preadipocyte number and the genetic expression of the studied genes did not differ be...

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...
