摘要: 目的 探讨As2O3联合canstatin蛋白对肿瘤血管内皮细胞(Td-EC)增殖、迁移、血管形成的影响及其凋亡的机制。方法 用肝癌HepG2细胞上清诱导人脐静脉内皮细胞(HUVEC)成为Td-EC。As2O3联合canstatin干预Td-EC,通过细胞迁移,流式细胞术,观察血管形成。结果 As2O3、canstatin及联合影响Td-EC迁移细胞数分别为32.60±1.51、26.60±1.14、21.00±1.87,显著低于对照组50.60±2.30(p<0.01),并促进凋亡、抑制管腔形成,以联合应用更显著。结论 As2O3联合canstatin在体外可特异地抑制Td-EC增殖、迁移、血管形成及其凋亡。

Abstract: Objective To study effect and the mechanism of As2O3combined with recombinant canstatin protein on tumor vascular endothelial cell proliferation, migration, angiogenesis and apoptosis.Methods The cells were induced to differentiate into tumor-derived endothelial cells ( Td-ECs) by co-culturing with supernatants of HepG2 cells. The anti-effect of As2O3 and canstatin on Td-ECs was detected with cell migration, flow cytometry, blood vessel formation assay. Results As2O3 ,canstatin and the combined all effected on Td-EC in vitro inhibited their migration cells respectively: 32.60±1.51、26.60±1.14、21.00±1.87,significantly higher than control group 50.60±2.30(p<0.01),and promoted apoptosis, blood vessel formation.The effect of combined was more significant.Conclusion As2O3 combined with recombinant canstatin protein in vitro inhibits Td-EC proliferation, migration, angiogenesis and promotes apoptosis.
