  • Effect of Tumor Necrosis Factoralpha Genetransduced Tumor Vaccine in Mice Liver Cancer Implanted Tumors

    ;ObjectiveUsing human tumor necrosis factoralpha (TNFα) genetransduced human liver cancer cell BEL7404 as tumor vaccine, to study the effect of immune rejection to mice liver cancer implanted tumors. MethodsMice were divided into five groups, and were inoculated with TNFα genetransduced BEL7404 cells which irradiated with 60Co (BEL7404TNFCo group), TNFα genetransduced BEL7404 cells (BEL7404TNF group), BEL7404 cells (BEL7404 group), BEL7404 cell irradiated with 60Co (BEL7404Co group) respectively. Normal saline was injected in control group. Then mice liver cancer H22 cells were implanted to each group, the growth of mice liver cancer implanted tumors was observed. The apoptosis index of implanted tumors was detected by TUNEL method.ResultsCompared to BEL7404 group,BEL7404Co group and control group, the tumor vaccine which did not transduce with TNFα gene and the control group, the tumorigenesis rate of liver cancer implanted tumors was reduced, the growth of implanted tumors was inhibited and the apoptosis of implanted tumors was increased in BEL7404TNFCo group,P<0.01.There was no difference between BEL7404TNFCo group and BEL7404TNF group,Pgt;0.05. ConclusionHuman tumor necrosis factoralpha genetransduced human liver cancer cell can be used as tumor vaccine, it has quite b effect of immune rejection to mice liver cancer implanted tumors.
