The impact of cell period and cell surface antigen in cervical cancer cell lines by interferon-? gene transfer / 中国癌症杂志

Purpose:To explore the tumor cell responses after IFN-? gene transfer by analyzing the expression of cell surface antigen,apoptosis and the impact of cell period. Methods:We constructed IFN-? gene expression vector-pcDNA3- IFN-?, and transfected it into HeLa cell lines by Lipofectamine. The expression of IFN-??the Human Leukocyte antigen(HLA-DR) after gene transfer were measured. The apoptosis of tumor cells and the variety of cell period were also measured to investigate the anti-tumor mechanism by IFN-? gene therapy. Results:The results showed that the HLA-DR expression in Hela cell lines increased significantly(P
