Construction of Expression Vector for Anti-Alpha-Fetoprotein Gene and Its Inhibition Effects on Alpha-Fetoprotein Positive Hepg2 Cells

As research previously demonstrated, suppression of AFP expression or its biological activities might inhibit the proliferation of AFP positive human hepatocellular carcinoma cells. In this study, we constructed an anti-AFP gene vector and transfected it to HepG2 cells. RT-PCR showed AFP gene expression in the transfected cells was reduced. MTT assay suggested the proliferation of the transfected cells was also inhibited comparing with the untransfected cells. This result provides a new insight into AFP as the target for preventing and treating hepatocellular carcinoma.
