摘      要：STAT3 plays a particularly important role in several cancer-related signal transduction *** STAT3 via RNA interference or small molecule inhibitors induces the apoptosis of tumor cells,thereby inhibiting the growth of the *** this study,short-hairpin RNA sequences targeting the STAT3 genes were designed,synthesized,and then connected to pGPU6/GFP/Neo plasmids as the shRNA-expression *** expression of STAT3-shRNA was analyzed by real-time PCR,western blotting,and cell apoptosis assay to study the growth and apoptosis of the ***,the effect of STAT3 knockdown on the NCI-H1650 cells was studied in a tumor mouse *** results revealed that,after an in vitro transfection,the proliferation of NCI-H1650 cells was inhibited,and the cells were induced to *** mRNA and protein expression levels of STAT3 were downregulated in the STAT3-shRNA *** vivo,the tumor mass and volume in the STAT3-shRNA group were significantly lower than in the other two *** the in vivo and in vitro results demonstrated a long-period inhibiting effect on NSCLC,especially in vivo,when the tumor inhibition rate could reach 50%in the STAT3-shRNA group,which is an exciting ***,the study of the conjugation of STAT3-shRNA and chitosan-based vectors revealed that they could be combined steadily with good cytocompati-bility and transfection *** results together provide convincing evidence for the application of STAT3-shRNA used in the treatment of non-small lung cancer,which could be a promoting prospect for the development of gene therapy.
