Abstract:
Objective To investigate the effect of RNAi-mediated survivin gene with conditionally replicating adenovirus Ad-de-lE1b55KD-shRNA/survivin-EGFP silencing on propagation and apoptosis of colon carcinoma cell lines HT-29 .Methods Ad-de-lE1b55KD-shRNA/survivin-EGFP was transfected to transplantation tumor on athymic mouse ,replication defective adenovirus and liposome vector which was contained the same shRNA as Ad-delE1b55KD-shRNA/survivin-EGFP were as control one .Then the change of transplantation tumor on athymic mouse was tested ,and TUNEL was used to assay the apoptosis rate of transplantation tumor cells .Results After transfection of Ad-delE1b55KD-shRNA/survivin-EGFP ,the quality of transplantation tumor on athymic mouse were reduced and the apoptosis rate of transplantation tumor cells were higher than replication defective adenovirus and lipo -some vector which was contained the same shRNA (P<0 .05) .Conclusion The effect of Ad-delE1b55KD-shRNA/survivin-EGFP to colon carcinoma cell on propagation and apoptosis were higher than replication defective adenovirus and liposome vector .
