BEZ235 联合AZD6244 对宫颈癌细胞增殖、迁移的影响

目的 探讨联合应用PI3K 和mTOR 双重靶向抑制剂BEZ235 及上皮间质转换（EMT）抑制剂AZD6244 对人宫颈癌细胞增殖、迁移能力的影响。方法 采用MTT 法分析BEZ235、AZD6244 对Hela和SiHa 细胞增殖能力的影响，损伤愈合实验检测BEZ235、AZD6244 对Hela和SiHa 细胞迁移能力的影响，Western blot 检测BEZ235、AZD6244 对EMT 相关标志物蛋白的表达变化。结果 BEZ235、AZD6244 对宫颈癌细胞Hela 和SiHa 的增殖有协同抑制作用；联合应用BEZ235、AZD6244 可以通过EMT 途径抑制Hela和SiHa 细胞的侵袭、迁移。结论 BEZ235、AZD6244 联合应用可体外抑制Hela 和SiHa 细胞的增殖、迁移，其部分机制是通过抑制EMT 途径实现的。

Effect of co-treatment with BEZ235 and AZD6244 on proliferation andmigration of cervical cancer cells in vitro

Objective To detect the effect of co-treatment with BEZ235 (inhibitor of PI3K and mTOR)and AZD6244 (inhibitor of EMT) on the proliferation and migration of human cervical carcinoma cell lines Helaand Siha. Methods Cell proliferation ability was detected by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-Htetrazoliumbromide (MTT) assay, and the capacity of cell migration was measured by wound healing assay.Western blot was used to detect the changes of the expressions of EMT-related proteins. Results The proliferationof Hela and SiHa cells was effectively inhibited by co-treatment with BEZ235 and AZD6244. In addition, thecombined treatment also synergically suppressed the invasion and migration of Hela and SiHa cells through EMTpathway. Conclusions Combined treatment with BEZ235 and AZD6244 may synergically inhibit the proloferationand migration of cervical cancer cells in vitro , and part of the mechanism may be completed by weakening the EMTpathway.
