Role of Peroxisome Proliferator-Activated Receptors (PPARs) in Trophoblast Functions

Downregulation of peroxisome proliferator-activated receptors (PPARs) in nasal polyposis

BACKGROUND Peroxisome proliferator-activated receptor (PPAR) alpha, betadelta and gamma are nuclear receptors activated by fatty acid metabolites. An anti-inflammatory role for these receptors in airway inflammation has been suggested. METHODS Nasal biopsies were obtained from 10 healthy volunteers and 10 patients with symptomatic allergic rhinitis. Nasal polyps were obtained from 22 patients...

Peroxisome Proliferator-Activated Receptors (PPARs): Choreographers of Metabolic Gene Transcription

Nuclear receptors are ligand-activated transcription factors that regulate gene expression in response to small lipophilic compounds such as testosterone [androgen receptor (AR)], oxysterols [liver X receptor (LXR)], estrogen (ER), xenobiotics [pregnane X receptor (PXR)], retinoic acid (RAR), thyroid hormone (TR), bile acids [farnesoid X receptor (FXR)] and vitamin D (VDR). The peroxisome proli...

Peroxisome Proliferator-activated Receptors

Peroxisome proliferator-activated receptors (PPARs) are members of the ligand-activated nuclear hormone receptor superfamily of transcription factors that includes receptors for steroids, thyroid hormone, retinoic acid, and vitamin D. Upon activation in the cytoplasm, PPARs heterodimerize with retinoid X receptors (RXR) and form a complex that translocates to the nucleus and regulates gene expr...

The role of Toll-like receptors (TLRs) and peroxisome proliferator activated receptors (PPARs) in endotoxin caused liver injury

Role of Peroxisome Proliferator-Activated Receptors in Inflammation Control

Peroxisome proliferator-activated receptors (PPARs) were discovered over a decade ago, and were classified as orphan members of the nuclear receptor superfamily. To date, three PPAR subtypes have been discovered and characterized (PPAR $\alpha$, $\beta/\delta$, $\gamma$ ). Different PPAR subtypes have been shown to play crucial roles in important diseases and conditions such as obesity, diabete...
