Activation of peroxisome proliferator-activated receptors (PPARs) by their ligands and protein kinase A activators.
The nuclear peroxisome proliferator-activated receptors (PPARs) alpha, beta, and gamma activate the transcription of multiple genes involved in lipid metabolism. Several natural and synthetic ligands have been identified for each PPAR isotype but little is known about the phosphorylation state of these receptors. We show here that activators of protein kinase A (PKA) can enhance mouse PPAR acti...
متن کاملDownregulation 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...
متن کاملPeroxisome 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...
متن کاملPeroxisome 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...
متن کاملThe toxicology of ligands for peroxisome proliferator-activated receptors (PPAR).
Peroxisome proliferator-activated receptors (PPARs) are ligand activated transcription factors that modulate target gene expression in response to endogenous and exogenous ligands. Ligands for the PPARs have been widely developed for the treatment of various diseases including dyslipidemias and diabetes. While targeting selective receptor activation is an established therapeutic approach for th...
