The dynamic expression profile of forkhead transcription factor genes in normal Balb/c mice and after bile duct ligation / 国际检验医学杂志

ABSTRACT

Objective The present study was initiated to determine the expression profiles of the Fox genes in normal Balb/c mouse liver and their dynamic expression changes during fibrogenesis induced by experimental bile duct ligation(BDL).Methods RT-PCR was employed to detect 18 Fox family members including Foxo1,Foxo3,Foxm1,and Foxl1 in normal mouse liver.After mice were bile-duct-ligated,real time fluorescence quantitative PCR(FQ-PCR)was performed to ananlyze the dynamic mRNA expression changes of 9 inflammation-or proliferation-related Fox family genes.Results All the 18 Fox genes were found to be exDressed in the normal mouse liver and bile duct ligation profoundly influenced the expression of Fox transcriptional factor family genes.The expression of Foxol was significantly reduced by BDL,while FoxoL1 and Foxom1 expression were enhanced in this roodel.Moreover,the expression of Foxo1 and Foxo3 were the highest among the Fox members.Conclusion The Fox family genes-related to inflammation and proliferation were dynamically changed during BDL-induced liver injury,it indicates these genes were involved in the pathogenesis of liver fibrosis.
