Summary

Patients who accept long-term parenteral nutrition tend to suffer from liver injury. The mechanism for this injury has two possible explanations. The first possible reason is intrinsic toxic effects of parenteral nutrition. The second is the basic pathological condition of intestinal failure which includes infection, bacterial translocation, etc. Cholestasis is the lethal presentation of this kind of liver disease. Farnesoid X receptor (FXR) is a member of ligand-activated nuclear receptor superfamily. FXR serves as a sensor for bile acids and promotes enterohepatic clearance of bile acids by controlling the expression of genes involved in their transport and metabolism. Considering the activation of vitamin D receptor (VDR) by vitamin D can induce FXR-related genes in the liver.The hypothesis of this study is that vitamin D plays a key role in the prevention and reversion of the liver via VDR and/or FXR signaling pathway. Using a mouse cholestasis model based on short bowel syndrome and parenteral nutrition, the researchers will investigate the dynamic change of plasma vitamin D level. Afterward, intravenous supplement of vitamin D was added to this model to demonstrate vitamin D can ameliorate cholestasis. An in vitro system was developed to investigate the importance of FXR signaling pathway in this effect.
