Minireview: lipid metabolism, metabolic diseases, and peroxisome proliferator-activated receptors.
Lipid and carbohydrate homeostasis in higher organisms is under the control of an integrated system that has the capacity to rapidly respond to metabolic changes. The peroxisome proliferator-activated receptors (PPARs) are nuclear fatty acid receptors that have been implicated to play an important role in obesity-related metabolic diseases such as hyperlipidemia, insulin resistance, and coronar...
متن کاملPeroxisome Proliferator Activated Receptors and Lipoprotein Metabolism
Plasma lipoproteins are responsible for carrying triglycerides and cholesterol in the blood and ensuring their delivery to target organs. Regulation of lipoprotein metabolism takes place at numerous levels including via changes in gene transcription. An important group of transcription factors that mediates the effect of dietary fatty acids and certain drugs on plasma lipoproteins are the perox...
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 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 کاملThe biology of peroxisome proliferator-activated receptors: relationship with lipid metabolism and insulin sensitivity.
Peroxisome proliferator-activated receptors (PPARs) are transcription factors belonging to the superfamily of nuclear receptors. Three isoforms (alpha, delta, and gamma) have been described. They act on DNA response elements as heterodimers with the nuclear retinoic acid receptor. Their natural activating ligands are fatty acids and lipid-derived substrates. PPAR-alpha is present in liver, hear...
