activation of farnesoid X receptor FXR initiates a feedback regulatory loop via induction of small heterodimer partner, SHP, which suppresses liver receptor homolog 1, LRH-1, and HNF4alpha dependent expression of sterol 12alpha hydroxylase, CYP8B1, overview |

the enzyme is involved in bile acid synthesis, repression of bile acid synthesis and induction of basolateral bile acid export may represent adaptive mechanisms to limit bile acid burden in chronic cholestasis, but the changes do not sufficiently counteract cholestatic liver damage, overview |
