Objective To observe effects of AFP gene silenced by siRNA on apoptosis of hepatocellular carcinoma cell line EGHC-9901. Methods siRNA expressing plasmid aimed at AFP gene was firstly established and subsequently transfected into hepatocellular carcinoma cell line EGHC-9901 which had the high expression of AFP;after G418 positive clone selection for 4~5 weeks,expression of AFP mRNA and protein were respectively detected by semi-quantitative RT-PCR and Western blot.Then cells were divided into three groups: ...
