摘要: 目的: 考察重组表达的抑瘤素 M (oncostatin M,OSM) 对肿瘤细胞增殖转移的抑制能力 。方法: 在大肠杆菌中重组表达了人抑瘤素 M,并通过 MTT检测实验、软琼脂克隆形成抑制实验 、粘附抑制实验、细胞移动能分析实验和浸润杯实验来考察重组hOSM 对高转移人肺腺癌细胞 95-D 增殖和侵袭转移过程的抑制能力。结果: 重组 hOSM 在上述体外模型中能以较低浓度有效抑制 95-D 肿瘤细胞的增殖和转移 。结论: 原核表达的人抑瘤素 M 在对肺癌的临床治疗中具有潜在的应用价值。

Abstract: AIM: To investigate the inhibition ability of recombinant Oncostatin M(OSM) to proliferation and migration of tumorcells.METHODS: Expressed and purified human OSM from recombinant E.Coli,and as-sayed its pharmacology activity by a series of experiments in vitro to metastatic human lung cancercell line 95-D including MTT assay,clone formationassay in soft agar,cell attachment assay,cell migration assay and invasion cuPassay.RESULTS AND CONCLUSION: rhOSM displayed strong activity of inhibiting the proliferation and migration of 95-D.Prokaryoticly expressed hOSM has po-tential clinical value to lung cancer.

Key words: oncostatin M, metastatic human lung cancercell line 95-D, metastasis
