Apolipoprotein B (ApoB) plays a major role in the regulation of cellular cholesterol homeostasis and pathogenesis of atherosclerosis. This protein acts as a ligand for the cellular recognition and catabolism of low density lipoprotein (LDL) by the LDL receptor. Previous studies have shown that the expression of apoB in hepatic cells is regulated by the interaction of factors binding to enhancer elements in intron 2 and three elements designated III, IV and V. These elements lie within regions respectively -86 to -62, -72 to -53 and -53 to -33 from the ApoB promoter. In this study, we have suggested that transcription factor C/EBPalpha, which binds to the -53 to -33 region of the apoB, interacts with the HNF-4 synergistic complex and C/EBPalpha factors within -86 to -53 and may contribute to increase transcription of the ApoB gene.Downloads
