重组人血管内皮抑素体外对肝癌HCCLM6细胞转移侵袭的影响

目的 研究重组人血管内皮抑素在体外对人肝癌HCCLM6细胞粘附、迁移及侵袭的抑制作用.方法 分别以25、50、100、200、400μg/ml的重组人血管内皮抑素在体外处理HCCLM6细胞,采用MTT法检测药物对细胞增殖的影响,利用transwell小室及matrigel胶体外检测药物对细胞迁移、侵袭及粘附的影响.结果 重组人血管内皮抑素作用HCCLM6细胞72 h后对细胞增殖存在一定的抑制作用;重组人血管内皮抑素可明显抑制HCCLM6细胞与matrgel的黏附、对人工基底膜的侵袭力和迁移力,且抑制作用均呈剂量依赖性.结论 重组人血管内皮抑素具有直接抑制人肝癌细胞体外侵袭转移和增殖作用,其机制有待进一步探讨.

Inhibitory effects of recombinant human endostatin on the metastatic potential and invasiveness of hepatocellular carcinoma HCCLM6 cells in vitro

OBJECTIVE: To investigate the inhibitory effects of recombinant human endostatin (rh-ES) on cell adhesion, metastatic potential and invasiveness of hepatocellular carcinoma HCCLM6 cells in vitro. METHODS: The changes in the cell proliferation status of HCCLM6 cells treated with different concentrations of rh-Endostatin in vitro was measured with MTT assay, and their invasiveness and migration were assayed using transwell cell culture chamber. The cell adhesion assay was carried out on 96-well plate precoated with matrigel. RESULTS: Rh-ES showed inhibitory effect against the proliferation of HCCLM6 cells after a 72-h treatment. The adhesion, metastatic potential and invasiveness of the cells were obviously inhibited by rh-Endostatin in a dose-dependent manner. CONCLUSION: Rh-ES inhibits the adhesion, invasiveness and migration of hepatocellular carcinoma cells in vitro, and the mechanism needs further investigation.
