Objective(s): Pioglitazone (PGZ), a peroxisome proliferator-activated receptor gamma (PPAR-γ) agonist, has significant neuroprotective effects and has been reported to regulate inflammatory processes.Materials and Methods: We evaluated the effects of PGZ on febrile seizure (FS) in rat pups. Three groups of male rat pups received intraperitoneal (IP) injections of PGZ (5, 10, and 20 mg/kg). Lipo...

Peroxisome proliferator-activated receptors (PPAR) are members of the nuclear hormone receptor superfamily of ligand-activated transcription factors. Three PPAR isoforms, designated PPARalpha, -beta/delta, and -gamma, have been identified and attracted enormous attention as a result of the key role that these receptors play in regulating adipogenesis, lipid metabolism, insulin sensitivity, infl...

In a systematic search for peroxisome proliferator-activated receptor-gamma (PPAR-gamma) target genes, we identified S3-12 and perilipin as novel direct PPAR-gamma target genes. Together with adipophilin and tail-interacting protein of 47 kDa, these genes are lipid droplet-associating proteins with distinct expression pattern but overlapping expression in adipose tissue. The expression of S3-12...

We previously reported a syndrome of severe hyperinsulinemia and early-onset hypertension in three patients with dominant-negative mutations in the nuclear hormone receptor peroxisome proliferator-activated receptor (PPAR)-gamma. We now report the results of further detailed pathophysiological evaluation of these subjects, the identification of affected prepubertal children within one of the or...

Introduction and Aim: Hyperlipidemia is a worth-mentioning risk factor for variety of rapidly spreading diseases such as cardio-vascular diseases, myocardial infarction, impaired glucose tolerance metabolic syndrome. Peroxisome proliferator-activated receptor - gamma (PPAR-?), sirtuin 1 (SIRT1), forkhead box 1(FOXO1), liver X receptor-alpha (LXR-?) are the important determinants hyperlipidemia ...

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...

Protease inhibitors used in the treatment of HIV infection have been causally associated with lipodystrophy and insulin resistance and were shown to alter adipocyte differentiation in cultured cells. We aimed to delineate the mechanism by which indinavir impaired adipocyte function. We report that indinavir altered neither the growth nor insulin sensitivity of 3T3-F442A preadipocytes, nor did i...

BACKGROUND Peroxisome proliferator-activated receptor gamma (PPAR gamma) is a nuclear receptor whose activation has been shown to modulate macrophage and T cell-mediated inflammation. The objective of this study was to investigate the mechanisms by which the deletion of PPAR gamma in T cells modulates immune cell distribution and colonic gene expression and the severity of experimental IBD. M...

5-aminosalicylic acid (5-ASA) is an antiinflammatory drug widely used in the treatment of inflammatory bowel diseases. It is known to inhibit the production of cytokines and inflammatory mediators, but the mechanism underlying the intestinal effects of 5-ASA remains unknown. Based on the common activities of peroxisome proliferator-activated receptor-gamma (PPAR-gamma) ligands and 5-ASA, we hyp...

Uncoupling protein (UCP) is expressed only in brown adipocytes and is responsible for the unique thermogenic properties of this cell type. The novel brown preadipocyte cell line, HIB-1B, expresses UCP in a strictly differentiation-dependent manner. Transgenic mice studies have shown that a region from kb -2.8 to -1.0 of the marine UCP gene is required for brown adipocyte-specific expression. Su...
