Effect of Gemcitabine on viability and apoptosis of non-small cell lung cancer HCC827 in vitro / 中国免疫学杂志

ABSTRACT

Objective:To observe the effect of Gemcitabine ( GEM) on the viability and apoptosis of non-small cell lung cancer HCC827 in vitro. Methods:The cell viability,apoptosis and cell cycle of HCC827 cells induced by Gemcitabine were detected with cell counting kit-8 assay (CCK-8),Annexin V-FITC/PI staining and flow cytometry. The expression of Bcl-2 protein of cells treated with GEM was examined by Western blot assay. Results: There was significant inhibition effect on HCC827 cells treated with 0. 1-1 000 ng/ml of GEM,which can promote the occurrence of HCC827 cell apoptosis and arrest cell in the S phrase. The apoptosis induced by GEM was accompanied with the down regulation of Bcl-2 protein. Conclusion: GEM can inhibit the cell viability and induce the HCC827 cell apoptosis and S phrase arrest. Its cell dead type was apoptosis,which was related with the expression of Bcl-2 protein.
