学习的目的是在人的脐的静脉 endothelial 房间(HUVEC ) 和人的肺腺癌房间线 A549 的增长上调查 Demethyl bryoanthrathiophene (DBT ) 的效果的目的,和在 vitro 的 HUVEC 上的 DBT 的 antiangiogenic 效果。方法 MTT 试金被用来在 vitro 在 HUVEC 和 A549 房间,扁平的板苛责试金和试管形成的增长上观察 DBT 的效果测试被用来在移植和 HUVEC 的形成 vaso 的能力上观察 DBT 的影响。apoptosis 和 HUVEC 的房间周期上的 DBT 的效果被流动 cytometry 计算。结果 MTT 试金证明有 DBT 的处理导致了强壮的抑制到 HUVEC 和 A549 细胞的生长。HUVEC 和 A549 房间上的 DBT 的抑制效果与相关性的剂量和时间有关。在为 24 h 的扁平的板苛责的 DBT (0.16, 0.32 和 0.48 mol/L ) 的不同剂量,到 HUVEC 的移植的 DBT 的抑制率分别地是 14.70% , 38.23% 和 58.82% 。在从 0.04 的 DBT 的剂量,为在试管形成的 24 h 的 0.20 ~ 0.40 mol/L,有意义差别(P < 0.01 ) 在 angiogenesis 和不完全的血容器的减少的数字与控制组相比。所有结果证明 DBT 支持了伴随的 DBT 的集中的 HUVEC,和增加的 apoptosis 率 apoptosis 的加速率。结论 DBT 能禁止 HUVEC 和 A549 房间的增长,并且有效地在 vitro 压制 angiogenesis。
Objective:The aim of the study was to investigate the effect of Demethyl bryoanthrathiophene(DBT) on proliferations of human umbilical vein endothelial cells(HUVECs) and human lung adenocarcinoma cell line A549,and antiangiogenic effect of DBT on HUVECs in vitro.Methods:MTT assay was used to observe the effect of DBT on proliferations of HUVECs and A549 cells,flat plate scarification assay and tube formation in vitro test were used to observe the impact of DBT on migration and vaso-formed ability of HUVECs.The effects of DBT on apoptosis and cell cycle of HUVECs were calculated by flow cytometry.Results:MTT assay showed that treatment with DBT resulted in strong inhibition to the growth of HUVECs and A549 cells.The inhibition effects of DBT on HUVECs and A549 cells were related to dosage and times of dependency.In different doses of DBT(0.16,0.32 and 0.48 μmol/L) of flat plate scarification for 24 h,inhibition rates of DBT to migration of HUVECs were 14.70%,38.23% and 58.82%,respectively.In dose of DBT from 0.04,0.20 to 0.40 μmol/L for 24 h in tube formation,there were significance differences(P 0.01) in the decreasing number of angiogenesis and incomplete blood vessel compared with control groups.All results showed that DBT promoted the apoptosis rate of HUVECs,and the increase of concentration of DBT accompanied the acceleration of apoptosis rate.Conclusion:DBT could inhibit the proliferations of HUVECs and A549 cells,and effectively suppress angiogenesis in vitro.
