ABSTRACT
Objective:To evaluate the role of ERBB2 interacting protein (Erbin)in liver tissues in blood coagulation of septic mice.Methods:Thirty SPF healthy male C57BL/6 mice and 30 Erbin knockout mice, aged 8-10 weeks, weighing 20-30 g, were divided into wild-type+ sham operation group (WT+ Sham group), wild-type+ sepsis group (WT+ SEP group), Erbin gene knockout+ sham operation group (EKO+ Sham group) and Erbin gene knockout+ sepsis group (EKO+ SEP group) by a random number table method, with 15 animals in each group. The mouse sepsis model was prepared by the cecal ligation and perforation method in anesthetized animals. Eye blood samples were collected at 24 h after surgery and liver tissues were obtained for microscopic examination of histopathological changes (by HE staining) which were scored and for determination of plasma alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities (by colorimetry), expression of Erbin and tissue factor (TF) (by Western blot), expression of tissue plasminogen activator (t-PA) and fibrinogen (Fib)mRNA (by quantitative polymerase chain reaction), concentrations of PT, APTT, thrombin time (TT) and Fib (by automatic coagulation analyzer), and plasma TF and interleukin-6 (IL-6) concentrations (by enzyme-linked immunosorbent assay).Results:Compared with WT+ Sham group, the lung injury score was significantly increased, the expression of TF, t-PA mRNA and FGA mRNA was up-regulated, PT, APTT and TT were prolonged, the plasma Fib concentration was increased, and the activities of ALT and AST and concentrations of TF and IL-6 in plasma were increased in WT+ SEP group ( P<0.05). Compared with WT+ SEP group, the lung injury score was significantly increased, the expression of TF, t-PA mRNA and FGA mRNA was up-regulated, PT, APTT and TT were prolonged, the plasma Fib concentration was increased, and the activities of ALT and AST and concentrations of TF and IL-6 in plasma were increased in EKO+ SEP group ( P<0.05). Conclusions:Erbin in liver tissues exerts an endogenous protective effect on blood coagulation by inhibiting the up-regulation of TF expression in septic mice.
