人宫颈癌顺铂耐药细胞系SiHa/cDDP的建立
Establishment of a Cisplatin-resistant Human Cervical Cancer Cell Line
摘要
Abstract
Objective To establish a cisplatin (cDDP)-resistant human cervical cancer cell line named SiHa/ cDDP and researched its biological characteristics. Methods The development of cDDP resistance in SiHa cell line was induced by continuously stepwise exposure of the cells to cDDP. Cell growth curve, doubling time and resistance index (RI) were evaluated by MTT analysis. The expression of P-gp, GST-it. Topo Ⅱ were assessed with immunocytochemical method. Results SiHa/cDDP cell line was successfully established which had stable growth, subculture, frozen reservation and resuscitation in the concentration of 2 μg/ml cDDP, doubling time was (45. 82±3. 69) h and RI to cDDP was 16. 131. It also showed different degrees of cross-resistance to several anticancer drugs. As compared to parental SiHa, SiHa/cDDP had over-expression in P-gp and GST-ti (P<0. 01), but Topo II showed no statistically significant differences. Conclusion We successfully established the cDDPresistant human cervical cancer cell line SiHa/cDDP, which may provide ideal experimental model for research of human cervical carcinoma.关键词
