Ligand type-specific Interactions of Peroxisome Proliferator-activated Receptor γ with Transcriptional Coactivators

Down-Regulation of STAT5b Transcriptional Activity by Ligand- Activated Peroxisome Proliferator-Activated Receptor (PPAR) and PPAR

The nuclear receptor peroxisome proliferator-activated receptor (PPAR) is activated by a diverse group of acidic ligands, including many peroxisome proliferator chemicals present in the environment. Janus tyrosine kinase-signal transducer and activator of transcription (JAK-STAT) signaling is activated by multiple cytokines and hormones and leads to the translocation of dimerized STAT proteins ...

Effect of peroxisome proliferator-activated receptor γ on inflammatory markers

Introduction In a recent study published in “ARYA atherosclerosis,” Pourmoghaddas et al. reported that administration of pioglitzone in non-diabetic patients with metabolic syndrome had no positive effect on inflammatory markers including high sensitive C-reactive protein, interleukin-10 (IL-10), and tumor necrosis factor-α (TNF-α).1 Peroxisome proliferator-activated receptors (PPARs) are ligan...

Role of Peroxisome Proliferator-Activated Receptor-γ in Vascular Inflammation

Vascular inflammation plays a crucial role in atherosclerosis, and its regulation is important to prevent cerebrovascular and coronary artery disease. The inflammatory process in atherogenesis involves a variety of immune cells including monocytes/macrophages, lymphocytes, dendritic cells, and neutrophils, which all express peroxisome proliferator-activated receptor-γ (PPAR-γ). PPAR-γ is a nucl...

Peroxisome Proliferator-Activated Receptor

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...
