Peroxisome proliferators-activated receptors (PPARs) are ligand-activated transcription factors that belong to the nuclear hormone receptor superfamily. The three PPAR isoforms (alpha, gamma and beta/delta) have been found to play a pleiotropic role in cell fat metabolism. Furthermore, in recent years, evidence has been found regarding the antiproliferative, proapoptotic, and differentiation-pr...

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...

PPAR is a member of a family of nuclear receptors/ligand–dependent transcription factors, which bind to hormone response elements on target gene promoters. An antiproliferative and proapoptotic action profile of PPAR has been described and PPAR may function as a tumor suppressor gene, but little is known about the role of PPAR in vascular remodeling. One group of human diseases that shows impre...

The Seoul 151-747 PPAR subgroup comprises three closely related mem-Korea bers: PPAR␣, ␥, and ␦. They are activated by a varie...

Note: The PPAR gamma gene, a member of the peroxisome proliferator-activated receptor (PPAR) subfamily of nuclear hormone receptors, is implicated in adipocyte differentiation and function. In order to regulate the transcription of target genes, the PPAR protein needs to form heterodimers with retinoid X receptors (RXRs). Three splice variants of PPAR gamma are known: PPAR gamma1, PPAR gamma2, ...

Peroxisome proliferator-activated receptor (PPAR) alpha and gamma are ligand-activated transcription factors belonging to the nuclear receptor family. PPAR alpha mediates the hypolipidemic action of the fibrates, whereas PPAR gamma is a receptor for the antidiabetic glitazones. In the present study, the UDP-glucuronosyltransferase (UGT) 1A9 enzyme is identified as a PPAR alpha and PPAR gamma ta...

Increased levels of triglyceride-rich lipoproteins provoke lipid accumulation in the artery wall, triggering early inflammatory responses central to atherosclerosis like endothelial adhesion molecule expression. The endogenous mechanisms limiting such reactions remain poorly defined. Lipoprotein lipase (LPL) plays a central role in lipid metabolism by hydrolyzing triglyceride rich lipoproteins ...

Peroxisome proliferator-activated nuclear hormone receptors (PPAR) are ligand-activated transcription factors that play pivotal roles in governing metabolic homeostasis and cell growth. PPARs are primarily in the nucleus but, under certain circumstances, can be found in the cytoplasm. We show here that PPAR(alpha) interacts with the centrosome-associated protein CAP350. CAP350 also interacts wi...
