ABSTRACT
The purpose of the study was to investigate the effect of sophoridine on the proliferation and apoptosis of human gastric cancer MKN45 cells and the possible mechanism. MKN45 cells were randomly divided into control and sophoridine (including 6 subgroups) groups. Cell proliferation was detected by methyl thiazolyl tetrazolium (MTT) colorimetric method. The protein expression of high mobility group-box 3 (HMGB3) was observed by immunocytochemical staining and Western blot. Hoechst 33342 staining method was used to observe the morphological changes of cells treated with sophoridine. Apoptosis was detected by flow cytometry. The results showed that the proliferation of cells was inhibited by 48-hour treatment of sophoridine in a dose-dependent manner. Compared with control group, sophoridine group showed decreased HMGB3 protein expression and increased apoptotic rate. These results suggest that sophoridine can inhibit the proliferation of MKN45 cells and promote their apoptosis, which may be related to down-regulation of HMGB3 protein expression.
