ABSTRACT
Objective:
To investigate the effect of blocking BRCAA1 gene expression with siRNA on the proliferation of tumor cell line MCF-7 and Rb gene expression.Methods:
RNAi was employed to specifically knock down BRCAA1 expression.MCF-7 cells were transfected with complexes constructed with lipids and chemically synthesized Pre-designed anti-BRCAA1 siRNAs.The total RNA was isolated and reversely transcribed after 48 h.The expressions of BRCAA1 and Rb mRNA were determined by Real-Time PCR.Results:
Compared with negative control,transfected MCF-7 cells had a 42.3% decrease in expression of BRCAA1 mRNA and an 11.1% increase in Rb mRNA expression.The inhibitory rate of MCF-7 cells proliferation was(81.6?6.1)%.Conclusion:
There may be some antagonistic effect between BRCAA1 gene and Rb gene in proliferation of tumor cells,which provides a potential target for anti-tumor gene therapy.
