Mechanism of lncRNA CTD-3252C9.4 on invasion and migration of pancreatic cancer Panc-1 cells in vitro

  • 摘要: 研究长链非编码RNA(lncRNA)CTD-3252C9.4对人胰腺癌细胞Panc-1体外迁移和侵袭的抑制作用及其机制。采用培养胰腺癌微球体的三维半固体体系中的表皮生长因子(epidermal growth factor,EGF)刺激培养Panc-1细胞;采用RT-qPCR检测lncRNA CTD-3252C9.4在Panc-1中的表达量和载体转染效率;采用划痕-愈合法和Transwell小室法检测lncRNA CTD-3252C9.4及其靶基因骨形态发生蛋白7(bone morphogenetix protein 7,BMP7)对Panc-1细胞侵袭和迁移能力的影响;采用Western blot验证靶基因BMP7和上皮间质转化(epithelial-mesenchymal transition,EMT)相关蛋白表达量的变化。结果表明:EGF能显著抑制Panc-1中lncRNA CTD-3252C9.4的表达,且该lncRNA能够通过抑制促癌基因BMP7的转录影响细胞侵袭和迁移能力,并且抑制肿瘤的EMT过程。
    Abstract: The aim of this study is to investigate the inhibitory effect of long non-coding RNA(lncRNA)CTD-3252C9. 4 on migration and invasion of human pancreatic cancer cell Panc-1 in vitro and its mechanism. Panc-1 cells were stimulated by epidermal growth factor(EGF)in three-dimensional semi-solid system of cultured pancreatic cancer spheres. RT-qPCR was used to detected the transfection efficiency of lncRNA CTD-3252C9. 4. The effects of lncRNA CTD-3252C9. 4 and bone morphogenetix protein 7(BMP7)on the invasion and migration of Panc-1 cells were detected by scratch healing method and Transwell chamber method. The changes of target gene BMP7 and epithelial-mesenchymal transition(EMT)related proteins were verified by Western blot. EGF could significantly inhibit the expression of lncRNA CTD-3252C9. 4 in Panc-1 cells. The lncRNA can affect cells invasion and migration by inhibiting the transcription of the oncogene BMP7, then inhibit the process of EMT of tumors.
