1 Bile acids and FXR repressed endogenous CYP7A1 but stimulated alpha-fetoprotein transcription factor (FTF) and small heterodimer partner (SHP) mRNA expression in HepG2 cells. Bile Acids and Salts nuclear receptor subfamily 0 group B member 2 Homo sapiens
2 Results revealed that FTF was a dominant negative factor that was induced by bile acid-activated FXR to inhibit both CYP7A1 and SHP transcription. Bile Acids and Salts nuclear receptor subfamily 0 group B member 2 Homo sapiens
3 Differential regulation of FTF and SHP expression by bile acids may explain the wide variation in CYP7A1 expression and the rate of bile acid synthesis and regulation in different species. Bile Acids and Salts nuclear receptor subfamily 0 group B member 2 Homo sapiens
4 Differential regulation of FTF and SHP expression by bile acids may explain the wide variation in CYP7A1 expression and the rate of bile acid synthesis and regulation in different species. Bile Acids and Salts nuclear receptor subfamily 0 group B member 2 Homo sapiens
