摘要: 目的 探讨人乳腺癌MCF-7细胞受蝙蝠葛碱(Dauricine,Dau)作用后,对5氟尿嘧啶(5-FU)敏感性的影响。方法 分别以终浓度为2.5 μg/mL的蝙蝠葛碱、50 μg/mL的5-FU、2.5 μg/mL的蝙蝠葛碱和50 μg/mL的5-FU作用于人乳腺癌细胞MCF-7,运用MTT法检测细胞增殖活性,Transwell实验分析细胞的迁移,DAPI染色检测细胞的凋亡,Western blot法检测cyclinD1和Bcl-2蛋白的表达。结果 MTT实验结果显示联合使用阈下浓度的蝙蝠葛碱增强了5-FU对细胞增殖的抑制;Transwell实验表明联合应用阈下浓度的蝙蝠葛碱进一步加剧了5-FU对细胞迁移的抑制;DAPI染色说明联合应用阈下剂量的蝙蝠葛碱加强了5-FU对细胞凋亡的诱导,Western blot实验表明联合应用阈下浓度的蝙蝠葛碱进一步抑制了cyclinD1和Bcl-2蛋白的表达。结论 蝙蝠葛碱可有效增强人乳腺癌MCF-7细胞对5-FU的敏感性。

Abstract: Objective The objective of this study was to investigate the effect of dauricine on the sensitivity of 5-fluorouracil(5-FU)in human breast cancer MCF-7 cells.Methods MCF-7 cells were treated with 2.5 μg/mL of dauricine,50 μg/mL of 5-FU,or 2.5 μg/mL of dauricine with 50 μg/mL of 5-FU,the cell proliferation was measured by MTT assay.The cell migration was determined by Transwell assay;The cell apoptosis was detected by DAPI staining;The expression of cyclin D1 and Bcl-2 gene was examined by Western blot.Results The results showed that the combination of subthreshold concentration of dauricine enhanced the inhibitory effect of 5-FU on proliferation in MCF-7 cells.The combined use of subcutaneous concentration of dauricine further aggravated the inhibitory effect of 5-FU on cell migration.The combination of subcapsular dauricine enhanced the induction of apoptosis by 5-FU.The combination of dauricine with 5-FU could inhibit the expression of cyclin D1 and Bcl-2 protein in MCF-7 cells.Conclusion Dauricine can effectively enhance the sensitivity of 5-FU in human breast cancer MCF-7 cells.
