Abstract:
Objective Acute liver failure is one of the significant causes of death clinically.It is important to explore new serum markers of liver injury for early diagnosis and prognosis prediction of severe liver disease.Hepassocin ( HPS) is a liver-specific mitogenic growth factor.Our study is intended to investigate the correlation between HPS serum levels and the degree of liver injury.Methods Firstly, a mouse model of acute liver injury was constructed via intraperitoneally injection with different doses of CCl4 .Then the survival rate, alanine aminotransferase ( ALT) , aspartate aminotransferase ( AST) and the pathological changes in the liver were detected.Meanwhile, ELISA assay was performed to detect the serum level of HPS.In addition, the mRNA level and protein level of HPS were detected by real-time PCR and Western blotting, respectively.Results The mortality rate was increased and the liver damage was aggravated with the increase of the CCl4 dose.Besides, the ALT and AST levels were also increased in a dose-dependent manner.Additionally, the mRNA and protein levels of HPS were significantly up-regulated and closely related to the degree of the liver injury in the model. Conclusion HPS can be used as a new marker of liver injury in mice.
