目的:研究半边旗提取物5F对乳癌细胞MDA-MB-231培养物(乳癌细胞培养物)诱导的人脐静脉内皮细胞(HUVEC)血管生成潜能的影响及其作用机制。方法:MTT法检测不同浓度5F对乳癌细胞培养物诱导的HU-VEC增殖的抑制作用;Transwell小室法检测不同浓度5F对乳癌细胞培养物诱导的HUVEC穿膜能力和趋化性运动能力的影响;细胞-基质黏附实验检测5F对乳癌细胞培养物诱导的HUVEC黏附能力的影响;RT-PCR、Western blot法检测不同浓度5F对乳癌细胞培养物诱导的HUVEC KDR、Flt-1 mRNA和蛋白表达的影响。结果:不同浓度5F处理6、24 h后对乳癌细胞培养物诱导的HUVEC的增殖有一定程度的抑制作用(F组间=64.852,F时间=131.393,P<0.001)。20、40、80μmol/L 5F可抑制乳癌细胞培养物诱导的HUVEC体外穿膜能力、趋化性运动能力和黏附基质能力(F=48.206、147.613、22.081,P均<0.001)。不同浓度5F作用于乳癌细胞培养物诱导的HUVEC 24 h后,下调HUVEC KDR、Flt-1 mRNA和蛋白的表达(mRNA:F=86.381、79.175;蛋白:F=36.621、127.910,P均<0.001)。结论:5F抑制乳癌细胞培养物诱导的HUVEC体外增殖、穿膜能力、趋化性运动能力和黏附基质能力,其机制可能与下调细胞KDR mRNA和蛋白的表达水平有关。

Aim:To investigate the effect and its possible mechanisms of Pteris semipinnata L extract(5F) on angio-genic abilities of human umbilical vein endothelial cells ( HUVEC) induced by the culture of human high metastatic breast cancer MDA-MB-231 cells.Methods:MTT assay was used to evaluate the cell proliferation of HUVEC induced by the cul-ture of MDA-MB-231 cells after being treated by 5F for 6 h and 24 h.The effect of 5F on invasion and migration of HUVEC induced by the culture of MDA-MB-231 cells was measured by transwell chamber assay .The adhesive potential of HUVEC cells induced by the culture of MDA-MB-231 cells was tested by cell-matrix adhesion assay .RT-PCR and Western blot were applied to detect the expression levels of KDR , Flt-1 mRNA and protein in HUVEC induced by the culture of MDA-MB-231 cells.Results:5F inhibited the proliferation of HUVEC induced by the culture of MDA-MB-231 cells after 6 h and 24 h treatment(Fgroup =64.852,Ftime =131.393,P<0.001).20, 40 and 80μmol/L 5F significantly inhibited the in-vasion, migration and adhesion to matrigel of HUVEC induced by the culture of MDA-MB-231 cells ( F =48.206, 147.613, 22.081,P<0.001).After 24 h treatment, 5F down-regulated the expressions of KDR, Flt-1 mRNA and protein (mRNA:F=86.381, 79.175;protein:F=36.621, 127.910,P<0.001) induced by the culture of MDA-MB-231 cells. Conclusion:5F could inhibit the proliferation , invasion, and migration of HUVEC induced by the culture of MDA-MB-231 cells and adhesion to matrix of HUVEC ,which may be involved in its down-regulation of the expression of KDR .
