DHCR7-DT and cholangitis: Notably, MGL genetic ablation was protective against DDC‐induced sclerosis cholangitis, as shown by diminished serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), without changes in alkaline phosphatase (AP) (Fig. 1A) but (trend‐wise) increased serum BAs (Supporting Fig. S1A).
