Apolipoprotein E (apoE) is an important protein involved in lipoprotein clearance and cholesterol redistribution. ApoE is abundantly expressed in astrocytes in the brain and is closely linked to the pathogenesis of Alzheimer's disease (AD). We report here that small molecule ligands that activate either liver X receptors (LXR) or retinoid X receptor (RXR)(More)
Liver X receptors (LXRs) regulate target genes that are critical in lipoprotein metabolism and atherosclerosis. Apolipoprotein AIV (ApoAIV) is an apolipoprotein that is associated with chylomicrons and high-density lipoproteins. Plasma ApoAIV level in humans is inversely correlated with coronary artery events and overexpression of ApoAIV in mice results in(More)
4alpha-(2-Propenyl)-5alpha-cholest-24-en-3alpha-ol (3) was shown recently in a Chinese hamster ovary (CHO) cell-based low-density lipoprotein receptor/luciferase (LDLR/Luc) assay to be a potent transcriptional activator of the LDL receptor promoter in the presence of 25-hydroxycholesterol. Because of the involvement of 12alpha-hydroxylation in the(More)
4Alpha-(2-propenyl)-5alpha-cholestan-3alpha-ol (LY295427) was previously identified from a Chinese hamster ovary (CHO) cell-based low density lipoprotein receptor/luciferase (LDLR/Luc) assay to be a potent transcriptional activator of the LDL receptor promoter in the presence of 25-hydroxycholesterol. To investigate the effect of the 24,25-unsaturation in(More)
Previous studies established that cells isolated from the chromatically distinct inner (primarily zona reticularis) and outer (zona fasciculata + zona glomerulosa) zones of the guinea pig adrenal cortex had vastly different steroidogenic capabilities; the outer zone produced far more cortisol than the inner zone. The mechanism(s) responsible for those(More)
