Objective:The aim of this study was to study the changes of SGC-7901 cells transfecting small hairpin RNA(shRNA) targeted Bcl-2 and celecoxib in vitro.Methods:To use the effective siRNA targeted to Bcl-2 by Lipofectamine 2000,the rate of cell growth inhibition of all groups was detected by multiply-table tournament(MTT) method,apoptosis rate was examined by flow cytometry and the expression of Bcl-2 was assayed by Elisa.Results:After siRNA was transfected to SGC-7901 cells,the rate of cell growth inhibition was increased,the joint group was higher by flow cytometry and the expression of Bcl-2 was lower by Elisa.Conclusion:The growth of SGC-7901 cells which was transfected siRNA has been inhibited,and the sensitivity to celecoxib has been increased.
