| Abstract | Objective: To explore the effects of Livin gene knock down using sequence-specific siRNA on apoptosis of human breast cancer cell ZR-75-30. Methods: Chemically synthesized double stranded RNA( dsRNA) targeting Livin was transfected into human breast cancer cell ZR-75-30 with lipofectamine(TM)2000. The transfection efficiency was observed under a fluorescence confocal microscope. Expression of Livin at both mRNA and protein levels were detected by reverse transcription-polymerase chain reaction(RT-PCR) and immunohistochemical analysis. The effects on apoptosis of ZR-75-30 cells were assessed by FCAS. Results: The Livin siRNA can effectively and specifically inhibited the expression of Livin gene in ZR-75-30. The inhibition rate was 53.66% at mRNA level and 58.32% at protein level. After 24h, (8.36 +/- 0.20)% cells transfected with siRNA were induced to apoptosis. Conclusion: Chemically synthesized short Livin-siRNA can effectively inhibit Livin over expression and remarkably induce apoptosis in human breast cancer cell line ZR-75-30. Livin RNAi has a potential value in gene therapy of breast cancer. |
