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...
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 کاملActivation 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 کاملActivation of mouse and human peroxisome proliferator-activated receptors (PPARs) by phthalate monoesters.
Administration of phthalates is known to cause toxicity and liver cancer in rodents through the activation of peroxisome proliferator-activated receptors (PPARs), and the monoesters appear to be the active metabolites that function as ligands of PPARs. There is evidence that PPARs exhibit significant species differences in response to ligand activation. In this study, the activation of mouse an...
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...
