Objective:To study the effect of the CXCR4-siRNA recombinant adenoviral vector on the expression of CXCR4 gene in SKOV3 cells.Methods:Recombinant adenoviral vector was linearized with PacⅠ.Then it was repeatedly packaged and amplified in HEK293 cells and transfected into SKOV3 cells.The SKOV3 cells were divided into three groups:siRNA group with adenovirus carrying RNA interference
negative group with vacant adenovirus vector
and control group without any infection.The expression level of CXCR4 gene in SKOV3 cells was measured by RT-PCR
Western blot and immunocytochemistry analysis.Results:The viral titers were 6×108 PFU/ml.The green fluorescent protein expressed highly in SKOV3 cells under fluorescent microscope.The CXCR4 gene was greatly inhibited after infection with CXCR4-siRNA recombinant adenoviral vector.Conclusion:The CXCR4-siRNA recombinant adenoviral vector can efficiently transfect targeted cells and silence the expression of CXCR4 gene
which would lay a foundation for the further study on clinical gene therapy of RNAi technology in ovarian cancer.
