英文摘要
Vitamin K is a fat-soluble vitamin that has multiple roles in blood coagulation, bone, joint, brain and so on. Vitamin K is a cofactor of gamma-glutamyl carboxylase (GGCX) that modulates substrates such as hepatic blood coagulation factors by carboxylation. Moreover, vitamin K also activates nuclear receptor SXR/PXR as a ligand. We generated conditional GGCX and PXR knockout mice to study the physiological and pathopysiological roles of vitamin K. PXR knockout mice displayed osteopenia. Liver-specific Ggcx knockout mice display short life span due to hemorrhage. Using these animal models we can study differential roles and mechanisms of vitamin K action.
