A stable HepG2 cell line harboring a human cholesterol 7 alpha-hydroxylase (CYP7A) minigene/luciferase reporter gene construct was selected for studying transcriptional regulation of CYP7A gene promoter. Insulin and phorbol
The human CYP4F2 gene encodes a LTB4 omega-hydroxylase P450 prominently expressed in liver and kidney that functions to metabolize and inactivate the pro-inflammatory eicosanoids, LTB4 and arachidonic acid. HepG2 cells transfected with CYP4F2 -506/-6…
The expression of cholesterol 7 alpha-hydroxylase mRNA levels in confluent HepG2 cultures was reduced by tauro- or glyco-conjugates of deoxycholate and chenodeoxycholate, but not by cholate. Ursodeoxycholates, on the other hand, stimulated the mRNA…
The gene encoding cholesterol 7alpha-hydroxylase (CYP7A1) is tightly regulated to control bile acid synthesis and maintain lipid homeostasis. Recent studies in mice suggest that bile acid synthesis is regulated by the fasted-to-fed cycle, and fasting…
