Abstract:
Objective This study was to investigate the expression of human interferon ?(huIFN ?) gene in colon cancer cells. MethodsThe whole length cDNA of huIFN ? was subcloned into the expression vector pcDNA 3 after sequence measurement. Lipofectamine was used to transfer huIFN ? gene into three colon cancer cell lines(LOVO?SW620?HCT116BG) .The integration and expression of huIFN ? were identified by PCR and RT PCR respectively, the activity of IFN ? expressed in different cell lines was measured by ELISA. Results PCR and RT PCR showed successful integration and sustained expression of huIFN ? in 3 colon cancer cell lines. Conclusion The huIFN ? can be effectively transduced into human colon cancer cells, and sustained expression was obtained.
