Peroxisome proliferator-activated receptors and liver X receptors in atherosclerosis and immunity.
Atherosclerosis is a primary cause of death in the United States, and the current obesity epidemic threatens to exacerbate its morbidity and mortality worldwide. Despite important cardiovascular treatment advances over the past few decades, new approaches are needed to curb dangerous health trends. Nuclear receptors are a superfamily of ligand-activated transcription factors. The discovery of s...
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 کاملThematic review series: skin lipids. Peroxisome proliferator-activated receptors and liver X receptors in epidermal biology.
The epidermis is a very active site of lipid metabolism, and all peroxisome proliferator-activated receptor (PPAR) and liver X receptor (LXR) isoforms are expressed in the epidermis. Activation of PPARalpha, -beta/delta, or -gamma or LXRs stimulates keratinocyte differentiation. Additionally, activation of these receptors also improves permeability barrier homeostasis by a number of mechanisms,...
متن کاملFibrates, glitazones, and peroxisome proliferator-activated receptors.
Several decades ago, fibrates were approved for the treatment of dyslipidemia, whereas thiazolidinediones were screened in animal models to improve glucose homeostasis and were subsequently developed for the treatment of type 2 diabetes mellitus. Relatively recently, these drugs were found to act via peroxisome proliferator-activated receptors, nuclear receptors that control lipid metabolism an...
متن کاملPeroxisome proliferator-activated receptors and cardiovascular remodeling.
Peroxisome proliferator-activated receptors (PPARs) are nuclear receptors that heterodimerize with the retinoid X receptor and then modulate the function of many target genes. Three PPARs are known: alpha, beta/delta, and gamma. The better known are PPAR-alpha and PPAR-gamma, which may be activated by different synthetic agonists, although the endogenous ligands are unknown. PPAR-alpha is invol...
