Effect of γ-interferon on the expresson of Fas, Bcl-2 on Hep-G2 hepatocellular carcinoma cells / 中国普通外科杂志

ABSTRACT

Objective　To investigate the influence of γ-interferon (γ-IFN) on liver cancer cell line (Hep-G2). Methods　Observing the expression of Fas and Bcl-2 by γ-IFN-pretreated Hep-G2 cells via immunohistochemical stain; subsequently treating these cells with adrimysin, and observing the cell death rate and apoptosis of these cell by MTT and electroscopy. Results　(1) γ-IFN up-regulating the expression of Fas protein and down-regulating Bcl-2 protein (P<0.05), and the sensitivity of pretreated hep-G2 cell to adrimysin was increased. Conclusions　γ-IFN can rise the sensitivity of Hep-G2 to adrimysin via regulating the expression of Fas and Bcl-2.
