BACKGROUND Peroxisome proliferator-activated receptor (PPAR)-gamma may counteract tissue fibrosis via its anti-inflammatory actions, while hypoxia, a new pro-fibrotic factor, reportedly modifies PPAR-gamma expression. However, the effects of hypoxia on the expression and anti-inflammatory actions of PPAR-gamma have yet remained to be clarified in renal tubular cells. METHODS Confluent human p...
Neutrophils (polymorphonuclear leukocytes [PMNs]) are critical to the immune response, including clearance of infectious pathogens. Sepsis is associated with impaired PMN function, including chemotaxis. PMNs express peroxisome proliferator-activated receptor-gamma (PPAR-gamma), a ligand-activated nuclear transcription factor involved in immune and inflammatory regulation. The role of PPAR-gamma...
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...
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, ...
T helper cells secreting interleukin (IL)-17 (Th17 cells) play a crucial role in autoimmune diseases like multiple sclerosis (MS). Th17 differentiation, which is induced by a combination of transforming growth factor (TGF)-beta/IL-6 or IL-21, requires expression of the transcription factor retinoic acid receptor-related orphan receptor gamma t (ROR gamma t). We identify the nuclear receptor per...
Peroxisome proliferator-activated receptor-gamma (PPAR-gamma) is a member of the nuclear receptor (NR) superfamily of ligand-activated transcriptional factors. Among other functions, PPAR-gamma acts as a key regulator of the adipogenesis. Since several cytokines (IL-1, TNF-alpha, TGF-beta) had been known to inhibit adipocyte differentiation in mesenchymal stem cells (MSCs), we examined the effe...
Recent studies have found that cyclooxygenase-2 (COX-2) protein expression was low and inducible with cytokines in prostate cancer cells (in the absence of serum) and that, in contrast, COX-2 expression was high in normal prostate epithelial cells (EC). Peroxisome proliferator-activated receptor-gamma (PPAR-gamma) was expressed at high levels in the prostate cancer cell line PC-3 but not in ECs...
Previous work has implicated PPAR gamma in the regulation of CD36 expression and macrophage uptake of oxidized LDL (oxLDL). We provide evidence here that in addition to lipid uptake, PPAR gamma regulates a pathway of cholesterol efflux. PPAR gamma induces ABCA1 expression and cholesterol removal from macrophages through a transcriptional cascade mediated by the nuclear receptor LXR alpha. Ligan...
MBX-102/JNJ39659100 (MBX-102) is in clinical development as an oral glucose-lowering agent for the treatment of type 2 diabetes. MBX-102 is a nonthiazolidinedione (TZD) selective partial agonist of peroxisome proliferator-activated receptor (PPAR)-gamma that is differentiated from the TZDs structurally, mechanistically, preclinically and clinically. In diabetic rodent models, MBX-102 has insuli...
Thiazolidinediones (TZDs) reduce insulin resistance in type 2 diabetes by increasing peripheral uptake of glucose, and they bind to and activate the transcriptional factor peroxisome proliferator-activated receptor-gamma (PPAR-gamma). Studies have suggested that TZD-induced activation of PPAR-gamma correlates with antidiabetic action, but the mechanism by which the activated PPAR-gamma is invol...
