Mitotic Catastrophe Induced by Chelidonine on Human Gastric Carcinoma SGC-7901 Cells

To study the mitotic catastrophe induction effect of chelidonine on human gastric carcinoma SGC-7901 cells, MTT assay was applied to detect the proliferation inhibition effect of chelidonine. Giemsa staining was used to observe the morphological changes of the nucleus in gastric cancer cells and mitotic index (MI) was calculated. The results showed that chelidonine could effectively inhibit the proliferation of SGC-7901 cells and the IC50 was 48.67μmol/L. After treatment with 6.25-25μmol/L chelidonine, the numbers of giant cells with two or more nuclei was increased along with the increase of drug concentration. The mitotic index of cells was significantly increased compared with that of the control group (P<0.01). The conclusion can be drawn that chelidonine can inhibit the proliferation of SGC-7901 cells by inducing mitotic catastrophe of gastric carcinoma cells.
