ABSTRACT
Aim To study the interference role of Bcl-2 siRNA on HL-60 cells. Methods Bcl-2 siRNA was synthesized in vitro transcription with silencer siRNA construction kit. The synthesized siRNA was transfected into HL-60 cells with lipid siPORT transfection. Forty-eight hours after the transfection, we used MTT and immunofluorescence to detect cell proliferation and apoptosis,and used RT-PCR and immunofluorescence to detect the level of Bcl-2 mRNA and Bcl-2 protein expression. Result Bcl-2 siRNA reduced the level of Bcl-2 mRNA and Bcl-2 protein expression in HL-60 cells and induced cell apoptosis. There was no difference on the effect of other groups compared with the control. Effective Bcl-2 siRNA specifically degraded Bcl-2 expression in the levels of mRNA and protein and induced HL-60 cells apoptosis.Conclusion These results indicate that siRNA is a highly specific tool for targeted gene knockdown. siRNA-mediated gene silencing is a reliable approach for large-scale screening of gene function and drug target validation.
