ABSTRACT
Objective:
To investigate the effect of survivin-siRNA plasmid on survivin expression in human lung cancer cell line A549, and to observe its effect on the apoptosis, proliferation, and chemosensitivity of A549 cells.Methods:
pSilencer-survivin-siRNA (survivin-siRNA) plasmid was constructed using pSilencer-U6 plasmid and was transfected into A549 cells. Expression of survivin mRNA and protein was examined by RT-PCR and Western blotting analysis, respec-tively. Apoptosis and proliferation of A549 cells were examined by DAPI staining and MTT, respectively.Results:
Sur-vivin-siRNA plasmid was successfully constructed, and it significantly inhibited survivin mRNA and protein expression in A549 cells. Survivin-siRNA transfection induced apoptosis, inhibited proliferation and increased chemosensitivity of A549 cells to cisplatin.Conclusion:
pSilencer-survivin-siRNA can silence survivin expression in A549 cells and subsequently inhibit proliferation, promote apoptosis, and enhance chemosensitivity of A549 cells to cisplatin. Survivin may serve as a potential target for gene therapy of lung cancer.
