Background: There is evidence that CD36 promotes foam cell formation through internalizing oxidized LDL (ox-LDL) into macrophages therefore, it plays a key role in pathogenesis of atherosclerosis. In addition, CD36 expression seems to be mediated by nuclear receptor peroxisome proliferator-activated receptor gamma (PPAR-γ). The aim of the present study was to evaluate and compare the effect of ...

The focus of the current review is to highlight some new insights into the molecular mechanism by which vitamin D, a potentially nutritionally modulated factor, influences adipogenesis. Recent studies, predominantly using the mouse 3T3-L1 pre-adipocyte cell culture model, have shown that the role of vitamin D in inhibiting adipogenesis is mediated at the molecular level through a vitamin D rece...

introduction: the inflammatory response requires a coordinated integration of various signaling pathway including cyclooxygenase (cox). cox catalyzes the formation of prostaglandins from arachidonic acid. among prostaglandins, 15-deoxy-d12, 14-prostaglandin j2 (15d-pgj2), an endogenous ligand of peroxisome proliferator-activated receptor-gamma (ppar-γ), has been demonstrated to have anti-inflam...

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...

Agonists of the peroxisome proliferator-activated receptor-gamma (PPAR-gamma) exert protective effects in several models of ischemia/reperfusion injury, but their role in stroke is less clear. The study investigates the effects of two PPAR-gamma agonists, rosiglitazone and pioglitazone, on oxidative stress and inflammatory response induced by ischemia/reperfusion in the rat hippocampus. Common ...

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...

Sepsis is a critical inflammatory condition from which numerous patients die due to multiple organ failure and septic shock. The vasoactive hormone adrenomedullin (AM) and its binding protein (AMBP-1) are beneficial in sepsis by abrogating the progression to irreversible shock and decreasing proinflammatory cytokine release. To investigate the anti-inflammatory mechanism, we studied to determin...

Oxidized low-density lipoprotein (oxLDL) has been shown to modulate transactivation by the peroxisome proliferator-activated receptor (PPAR)-gamma and by nuclear factor-kappaB (NF-kappaB). In the present study, the oxLDL signalling pathways involved in NF-kappaB transactivation were investigated by utilizing a reporter construct driven by three upstream NF-kappaB binding sites, and various phar...
