摘要

目的: 观察奥沙利铂(Oxaliplatin

L-OHP)与7-羟基星形孢菌素(7-hydroxystaurosporine

UCN-01)单独及联合应用对结肠癌细胞HCT116的增殖抑制作用

探讨其诱导细胞死亡的作用机制。方法: 应用MTT法检测L-OHP

UCN-01单药及联用对HCT116细胞的增殖抑制作用;应用流式细胞术、Western blot方法检测药物处理的结肠癌细胞凋亡; 应用HE染色法检测丝裂灾变的形态改变。结果: 低浓度L-OHP(6.25 μmol·L-1)与UCN-01(100 nmol·L-1)联用对结肠癌HCT116细胞的杀伤可产生协同作用

效果明显强于单独用药组;两药联用Annexin V阳性细胞率与UCN-01单用无明显差别

但死亡细胞明显增加;两药联用HCT116细胞的形态发生改变

巨核多核细胞较单独用药组增多约10%。结论: L-OHP与UCN-01联用对HCT116细胞的增殖具有协同抑制作用

诱导细胞发生凋亡和丝裂灾变。

Abstract

Objective: To observe the growth inhibitory effect of Oxaliplatin(L-OHP) and (7-hydroxystaurosporine

(UCN-01) on HCT116 colon cancer cell line in single or combination treatment

and to investigate its mechanisms. Method: The growth inhibitory effect was evaluated by MTT assay in single agent or combination treatment. Apoptosis was investigated by flow cytometry and Western blotting

and mitotic catastrophy was determined by HE staining. Result: Combination treatment of L-OHP in low concentration and UCN-01 has synergistic effect on killing HCT116 colon cancer cell line

which was more effective than single treatment. AnnerxinV positive cell rate showed no difference between combination treatment or UCN-01 alone. Cellular morphology of HCT116 cell was changed in combination treatment

and megakaryocytes and polykaryocytes in combination treatment were increased by approximately 10% compared with the single treatment. Conclusion: Combinition treatment of L-OHP and UCN-01 has synergistic inhibitory effect on HCT116 cell proliferation through inducing cell apoptosis and mitotic catastrophy.
