摘要 目的研究白细胞介素(IL)-8在骨肉瘤患者血清中的表达及对骨肉瘤细胞增殖、迁移的影响,探讨其在骨肉瘤发生、发展中的作用机制。方法酶联免疫吸附实验(ELISA)检测骨肉瘤患者与正常健康人血清中IL-8含量差异;细胞计数试剂盒(CCK)-8、Transwell小室及蛋白免疫印迹实验研究重组人IL-8对143B人骨肉瘤细胞增殖、迁移及细胞外信号调节激酶(ERK)蛋白表达的影响。结果与正常健康人比较,骨肉瘤患者血清IL-8水平显著增高(P<0.05),骨肉瘤临床Ⅲ级血清IL-8含量明显高于Ⅰ级和Ⅱ级(P<0.05),肿瘤浸润T2、T3阶段血清IL-8含量明显高于T1阶段(P<0.05);细胞培养24、48 h,不同浓度重组人IL-8可显著促进143B细胞增殖、迁移能力(P<0.05;P<0.01);细胞培养48 h,40、60 ng/ml重组人IL-8可显著上调143B细胞ERK蛋白表达量(P<0.05)。结论上调IL-8表达可经ERK信号通路参与骨肉瘤的恶性转化过程。
