Abstract

Objective To investigate the effect of radiative expression vector Egr1-survivin shRNA combined with irradiation on the apoptosis and radiotherapy sensitivity of esophageal squamous cell carcinoma ECA109 cells. Methods The radiative expression vector Egr1-survivin shRNA was designed and transfected into ECA109 cells by LipofectamineTM2000 before radiotherapy was started. The treatment with YM155 combined with irradiation was established as the main control. The expression levels of survivin mRNA and protein in each treatment group were detected 24 hours after treatment with qPCR and Western Blot respectively. The cell cycles and cell apoptosis of each treatment group were detected by flow cytometry 48 hours after treatment respectively. Results In ECA109 cells, the expression levels of survivin mRNA and protein were more significantly down-regulated in transfected Egr1-survivin shRNA plasmid combined with irradiation group than in YM155 combined with irradiation group, the blank control group, and the blank vector control group. Compared with the last three groups, G₂ and S cycle cell rates were significantly increased, while the apoptosis rate was clearly decreased in Egr1-survivin shRNA combined with irradiation group (P<0.01) respectively). Conclusions The radiative expression vector Egr1-survivin shRNA combined with irradiation can promote the apoptosis of ECA109 cells and enhance their radiotherapy sensitivity. It promises to be a therapeutic method in conjunction with radiotherapy.
