OBJECTIVE: The peroxisome proliferator-activated receptor-gamma (PPARgamma) plays a role in adipocyte differentiation and insulin sensitization. It has been shown that genetic variation in the PPARgamma gene alters body weight control, lipid and insulin ho ...
Sterols and cholesterol in particular are lipids that have been studied exhaustively in view of their vital role in diverse cellular functions. Recently, it has been recognized that cholesterol is not only an essential component for the formation of membra ...
Intracellular and extracellular cholesterol levels are tightly maintained within a narrow concentration range by an intricate transcriptional control mechanism. Excess cholesterol can be converted into oxysterols, signaling molecules, which modulate the ac ...
The ability to determine the location and relative strength of all transcription-factor binding sites in a genome is important both for a comprehensive understanding of gene regulation and for effective promoter engineering in biotechnological applications ...
High expression of transferrin receptor (TfR) on the membrane of erythroid cells accounts for the high level of iron required to sustain heme synthesis. Several studies indicate that during erythroid differentiation TfR expression is highly dependent on tr ...
The orphan nuclear receptor liver receptor homolog 1 (LRH-1) plays a central role in cholesterol homeostasis by regulating a number of hepatic and intestinal genes critical for reverse cholesterol transport and bile acid homeostasis. Herein, we describe th ...
The three types of peroxisome proliferator-activated receptors (PPAR), termed alpha, delta (or beta), and gamma, belong to the nuclear receptor superfamily. Although peroxisome proliferators, including fibrates and fatty acids, activate the transcriptional ...
The hypolipidemic fibrates and antidiabetic thiazolidinediones display potent triglyceride-lowering activities. Studies on the molecular action mechanisms of these compounds indicate that thiazolidinediones and fibrates exert their action by activating dis ...
The molecular mechanism by which hypolipidemic fibrates and antidiabetic thiazolidinediones exert their hypotriglyceridemic action are discussed. Increased activity of lipoprotein lipase (LPL), a key lipolytic enzyme, and decreased levels of apolipoprotein ...
Leptin is a hormone which is produced in adipose tissue and which plays a role in the regulation of energy homeostasis. The expression of the ob gene, encoding leptin, is under multi-hormonal control. We have shown previously that high doses of glucocortic ...
