ABSTRACT
Objective To explore effect of isoorientin on gastric cancer cell autophagy.Methods Isoorientin and autophagy activator and effect of inhibitors on proliferation of human gastric cancer cell line SGC-7901 by MTT assay.Cell apoptosis was detected by flow cytometry.Production of autophagy lysosomal in gastric cancer SGC-7901 cells was obseroved by AO and MDC staining.Characteristic expression of autophagy protein was analysed by Western blot.Results MTT assay indicated that isoorientin could inhibit gastric cancer cell growth, RAP has the same effects, but 3-MA inhibition of apoptosis.Flow cytometry was used to detect the apoptosis rate of isoorientin and RAP could promote cell apoptosis , while 3-MA had the opposite effect.In AO staining, the red light appeared in the cells, and the green fluorescence appeared in the cells of MDC staining, which showed that there was an autophagy in the cells.Western blot test found the isoorientin was cell autophagy specific protein LC-3II, Beclin-1 expression increased, 3-MA suppressed the expression of the two proteins, and RAP had the opposite effect.Conclusion Isoorientin could induce apoptosis in gastric cancer SGC-7901 cells, autophagy is involved in the process of death.
