Adenoviruses mediated BCL-X1 overexpression protects mice from fulminant hepatic failure / 中华实验和临床病毒学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To indentify the relation between hepatic cells apoptosis and the lesion of liver tissue in acute toxic lethal hepatitis.</p><p><b>METHODS</b>60 Wistar mice were randomly divided into normal control, model group and treatment group. Normal control and model group were pretreated by portal vein injection of normal saline, the treatment group was pretreated by portal vein injection of BCL-X1 adenoviruses. The mice of model group and treatment group were received an injection of D-galn and LPS to establish fulminant hepatic failure models 7 days after pretrement. To observe BCL-X1 expression, serum ALT, AST, hepatocyte apoptosis rate, and mortality rate of the three groups.</p><p><b>RESULTS</b>The BCL-X1 expression was higher in treatment group than in model group; 6 hours after fulminant hepatic failure models were established,the serum ALT, AST level of treatment group was lower than model group;The hepatocyte apoptosis rate of treatment group was lower than model group. The death rate of treatment group was lower than model group.</p><p><b>CONCLUSION</b>In fulminant mice hepatic failure models, the hepatocyte apoptosis rate has a positive correlation with death rate, the overexpression of BCL-X1 can decrease the hepatocyte apoptosis rate and the death rate.</p>
