Preliminary observation on proliferation and apoptosis of HSC-T6 and L02 induced by sulfasalazine

Objective:To investigate the effect of sulfasalazine on proliferation and apoptosis of HSC-T6 and L02 in culture. Methods:HSC-T6 and L02 were incubated with different concentration of sulfasalazine.Cell proliferation was assessed by CCK-8 assay,cell apoptosis was analyzed by annexin Ⅴ FITC/PI flow cytometry;and apoptotic morphology was examined by vital staining of acridine orange/ethidium bromide(AO/EB). Results:Compared with the control group,the proliferation of HSC-T6 was significantly inhibited by sulfasalazine in a time and dose-dependant manner,when the concentration of sulfasalazine in the medium reached a certain level range. The HSC-T6 apoptotic induced by sulfasalazine was confirmed by AO/EB and annexin Ⅴ FITC/PI.compared with the control group,the proliferation and apoptosis rate of L02 treated by group had no statistical significance,and AO/EB staining showed no apoptosis. Conclusion:Sulfasazinea at the same concentration can specifically inhibit the proliferation of HSC and induce HSC apoptosis.
