Abstract:
Objective:To investigate the suppression effect and apoptosis of the colon cell line HT-29 treated with adenovirus-expressed human hyperplasia suppressor gene(hHSG)and hyperthermia.Methods:Replication-defective recombinant adenovirus containing hHSG was constructed,and then infected into HT-29 cell line to detect its overexpression by western blot.The synergic effect with hyperthermia was observed,cell survival was assessed using Vi-CELL TMXR Cell Viability Analyzer,and cell apoptosis and cell cycle distribution were determined by flow cytometry.Results:After the cells were treated with 100 MOI(multiplicity of infection)Ad5-hHSG and heated at 42 ℃ for 1 h,the number of viable cells decreased sharply,compared with single treatment with Ad5-hHSG or 42 ℃ for 1 h(P
