| 摘 要： | 摘要：目的 探讨敲低NEDD9基因表达对胰腺癌BxPC-3细胞体内外功能的影响。方法 采用NEDD9 shRNA 干扰质粒（Y2602）敲低NEDD9表达，将预处理的BxPC-3细胞分为BxPC-3 Y2602组［转染干扰序列（Y2602）］、BxPC- 3 NC组（不做任何处理）及BxPC-3 Blank组［转染无义序列（Y007）］，通过平板克隆形成实验检测3组细胞增殖情况， 划痕实验及Transwell实验检测细胞迁移及侵袭能力，同时制备3组细胞悬液接种于裸鼠皮下成瘤建立动物模型，通 过比较3组裸鼠肿瘤生长情况及瘤体大小分析敲低NEDD9后对BxPC-3细胞体内功能的影响。结果 与其他2组对 比，BxPC-3 Y2602组细胞增殖受到抑制、迁移至小室下室面的细胞数减少、迁移距离缩短（P＜0.05）。BxPC-3 Y2602 组多时点检测条件下肿瘤的体积更小，瘤体质量更小（P＜0.05）。结论 敲低NEDD9基因表达抑制BxPC-3细胞体 内外增殖、迁移及侵袭能力，其是潜在的胰腺癌治疗靶点

| Abstract: | Abstract: Objective To investigate the effect of knockdown NEDD9 gene expression on functions of pancreatic cancer BxPC-3 cells in vitro and in vivo. Methods shRNA interference plasmid (Y2602) was used to inhibit the expression of NEDD9. BxPC-3 cells were divided into BxPC-3 Y2602 group (transfected Y2602), BxPC-3 NC group (without transfected) and BxPC-3 blank group［transfected nonsense sequence (Y007)］. The proliferation, cell migration and invasion ability of three groups were detected by plate cloning assay, scratch test and Transwell test, respectively. The cell suspension was prepared for nude mouse models. The tumor formation was compared between three groups. The effect of knockdown NEDD9 gene expression on functions of BxPC-3 was analyzed by comparing tumor growth and size. Results Comparing with other groups, it was found that the cell proliferation was significantly inhibited, the number of cells that migrated to the lower chamber was significantly reduced, the volume and weight of tumors were significantly lower in BxPC- 3 Y2602 group (P＜0.05). Conclusion The knockdown of NEDD9 gene expression can inhibit the proliferation, migration and invasion of BxPC-3 cells in vitro and in vivo, which is a potential therapeutic target for pancreatic cancer. |
