更正声明

本刊2014年第17卷第9期刊登的题为“Rap2a真核表达质粒的鉴定及其对肺癌细胞迁移能力的影响”[吴金霞, 桑苗苗, 曹文嘉, 等. Rap2a真核表达质粒的鉴定及其对肺癌细胞迁移能力的影响. 中国肺癌杂志, 2014, 17(9): 643-648.]一文中：第645页图1和第647页图6因作者失误导致图片错误，希望修正如下图。特此更正。对此深表歉意。

图1 Rap2a蛋白在肺癌细胞H1299和A549中的表达。A：Western blot检测Rap2a蛋白在各组中的表达；B：Rap2a蛋白灰度分析。与HUVEC组比较：**P＜0.01 (n=3).Fig 1 Rap2a protein expression in H1299 and A549 cell lines. A: Western blot was used to analyze the expression of Rap2a protein; B: Densitometric analysis of Rap2a. The intensity of Rap2a was quantified by densitometry (software: Image J, NIH).Compared with HUVEC group: **P＜0.01 (n=3).

图6 Rap2a过表达后明胶酶谱检测细胞分泌MMP2的情况。A：明胶酶谱检测细胞分泌MMP2情况；B：MMP2灰度分析。与vector组比较：**P＜0.01 (n=3).Fig 6 Gelatin zymography analysis of the relative enzyme activities of cleaved-MMP2 after overexpression of Rap2a. A: Gelatin zymography was used to analyze the expression of MMP2 after transfection with Rap2a; B:Densitometric analysis of MMP2. The intensity of MMP2 was quantified by densitometry (software: Image J, NIH).Compared with vector group: **P＜0.01 (n=3). MMP:matrix metalloproteinase.
