Members of the family of nuclear receptors that include peroxisome proliferator-activated receptors (PPARs) and retinoid X receptors (RXRs) are important mediators of selective gene activation during development and cellular differentiation. In this study, developmentally-specific PPAR and RXR patterns of expression that occur in somatic and germ cell populations in the testis were determined u...

Peroxisome proliferator-activated receptors (PPARs) belong to the nuclear family of ligand activated transcriptional factors and comprise three different isoforms, PPAR-α, PPAR-β/δ, and PPAR-γ. The main role of PPARs is to regulate the expression of genes involved in lipid and glucose metabolism. Several studies have demonstrated that PPAR agonists improve dyslipidemia and glucose control in an...

OBJECTIVE To investigate the anti-inflammatory effect of peroxisome proliferator-activated receptor-γ (PPAR-γ) on non-obese diabetic mice (NOD mice) with Sjogren's syndrome. METHODS 22 eight-week-old female NOD mice were randomly divided into 2 groups. Rosiglitazone and normal saline were administered in the PPAR-γ group and the control group respectively. At the age of 9, 12 and 15 weeks, on...

BACKGROUND L-Carnitine has been demonstrated to ameliorate cachectic symptoms. In the present study, we sought to investigate the role of the peroxisome proliferator-activated receptor-γ (PPAR-γ) signaling pathway in the ameliorative effects of L-carnitine on cancer cachexia in a colon-26 tumor-bearing mouse model. METHODS The cachectic mice received L-carnitine (p.o.) or etomoxir (i.p.), or ...

Purpose Fibroblast activation may play an important role in pterygium progression. Synthetic peroxisome proliferator-activated receptor γ (PPAR-γ) ligands have been shown to be effective antifibrotic agents against transforming growth factor β1 (TGF-β1) induced fibrosis in several tissues. We aimed to investigate the antifibrotic effects of the PPAR-γ ligand rosiglitazone in pterygium fibroblas...

Hepatoprotective potential of peroxisome proliferator activator receptor (PPAR)- α and - γ agonists, fenofibrate (FEN), and pioglitazone (PIO), respectively, against cyclophosphamide (CP)-induced toxicity has been investigated in rat. FEN and PIO (150 and 10 mg/kg/day, resp.) were given orally for 4 weeks. In separate groups, CP (150 mg/kg, i.p.) was injected as a single dose 5 days before the ...

The inflammatory response after polymer-based drug-eluting stent (DES) placement has recently emerged as a major concern. The biologic roles of peroxisome proliferator-activated receptor-γ (PPAR-γ) activators thiazolidinedione (TZD) remain controversial in cardiovascular disease. Herein, we investigated the antiinflammatory effects of pioglitazone (PIO) on circulating peripheral blood mononucle...

PPAR (Peroxisome proliferated activated receptor) have been identified as potential targets of type II diabetes. Peroxisome proliferators-activated receptors (PPAR γ) are group of nuclear receptor proteins. They play essential role in the cellular metabolism of carbohydrates, lipids and proteins, cell differentiation and development. PPARs function as transcription factors regulating the expres...

Rubi Fructus (RF) is known to exert several pharmacological effects including antitumor, antioxidant, and anti-inflammatory activities. However, its antiobesity effect has not been reported yet. This study was focused on the antidifferentiation effect of RF extract on 3T3-L1 preadipocytes. When 3T3-L1 preadipocytes were differentiating into adipocytes, 10-100  μ g/mL of RF was added. Next, the ...
