[Effect of RNA interference of CD59 gene on proliferation of non-small cell lung cancer cell line GLC-P in vitro].

OBJECTIVE: To investigate the effect of CD59 gene inhibition mediated by RNA interference on the proliferation and apoptosis of non-small cell lung cancer (NSCLC) GLC-P cells in vitro. METHODS: Recombinant plasmids for RNA interference of CD59 gene were constructed and transfected into GLC-P cells via lipofectamine 2000. The stably transfected cells were examined with real-time RT-PCR, MTT assay and enzyme-linked immunosorbent assay to investigate the changes in cell proliferation and apoptosis. RESULTS: Compared with the control cells, the cells transfected with CD59-siRNA showed significantly decreased expression levels of CD59 mRNA (P<0.05) and significantly inhibited cell proliferation. CONCLUSION: CD59 gene is highly expressed in NSCLC and RNA interference-mediated CD59 silencing can strongly inhibit the proliferation and induce apoptosis in GLC-P cells, which shed light on a potentially new target for targeted gene therapy of NSCLC.
