摘要 目的研究CXCL12/CXCR4自分泌环对非小细胞肺癌的转移潜能的影响并探讨其可能的机制。方法以空载体p IRES2-Zs Green1转染A549细胞株作对照,共筛选出A549-CXCL12、A549-Zs Green1两株稳转细胞株。检测A549-CXCL12(具有功能活性的CXCL12/CXCR4自分泌环,A549-CXCL12组)、A549-ZsGreen1(空载体转染对照组细胞株,A549-Zs Green1组)、A549-WT(野生型对照组细胞株,A549-WT组)3组细胞株的增殖、侵袭、迁移能力,同时检测3组细胞株基质金属蛋白酶(MMP)-2、MMP-9的表达水平。结果A549-CXCL12组与A549-Zs Green1组、A549-WT组比较,细胞增殖、侵袭、迁移能力显著提高(P<0.01),同时MMP-2、MMP-9的表达水平亦显著提高(P<0.01)。结论 CXCL12/CXCR4自分泌环促进了非小细胞肺癌的增殖、侵袭、迁移能力,并上调细胞MMP-2、MMP-9的表达水平,促进了非小细胞肺癌的转移潜能。
