WebJul 11, 2011 · One possible explanation for this observation is a role for DXR/p53 signaling to stabilize SHP proteins. Of note, it has been shown that SHP proteins are rapidly degraded in hepatocytes and that bile acids and bile acid-induced FGF19 signaling pathways increase SHP stability by inhibiting its ubiquitination and proteasomal degradation ( 27 ). WebBile acids lower triglyceride levels via a pathway involving FXR, SHP, and SREBP-1c. We explored the effects of bile acids on triglyceride (TG) homeostasis using a combination of molecular, cellular, and animal models. Cholic acid (CA) prevents hepatic TG accumulation, VLDL secretion, and elevated serum TG in mouse models of ...
