Regulation of Peroxisome Proliferator-activated Receptor γ Activity by Mitogen-activated Protein Kinase

Regulation of peroxisome proliferator-activated receptor-γ by angiotensin II via transforming growth factor-β1-activated p38 mitogen-activated protein kinase in aortic smooth muscle cells.

OBJECTIVE Peroxisome proliferator-activated receptor-γ (PPARγ) ligands attenuate angiotensin II (Ang II)-induced atherosclerosis through interactions with vascular smooth muscle cell (VSMC)-specific PPARγ in hypercholesterolemic mice. Therefore, the purpose of this study was to determine the mechanism of Ang II-mediated intracellular regulation of PPARγ in VSMCs. METHODS AND RESULTS Incubatio...

Mode of peroxisome proliferator-activated receptor γ activation by luteolin.

The peroxisome proliferator-activated receptor γ (PPARγ) is a target for treatment of type II diabetes and other conditions. PPARγ full agonists, such as thiazolidinediones (TZDs), are effective insulin sensitizers and anti-inflammatory agents, but their use is limited by adverse side effects. Luteolin is a flavonoid with anti-inflammatory actions that binds PPARγ but, unlike TZDs, does not pro...

Peroxisome proliferator - activated receptor

The peroxisome proliferator-activated receptors (PPARs) belong to the nuclear hormone receptor superfamily. All PPARs heterodimerize with the retinoid X receptor (RXR) and bind to specific regions on the DNA of target genes. The discovery of PPARγ as a target of multimodal insulin sensitizers has attracted remarkable scientific interest and had a great impact on the pharmaceutical industry. Thi...
