【技术实现步骤摘要】
LncRNA的UCA1和UCA1a共有序列对膀胱癌细胞生物学功能影响的检测方法
本专利技术属于生物医学
,特别是涉及一种LncRNAUCA1和LncRNAUCA1a共有序列在肿瘤细胞中的生物学功能研究,具体指该段序列对膀胱癌细胞的生物学研究,但不限于膀胱细胞。
技术介绍
LncRNA是一类转录本长度超过200nt的RNA分子,自身不能编码蛋白,曾因不编码蛋白而被称为“噪音RNA”。近年来的研究发现,LncRNA可以RNA的形式在多种层面上调节基因的表达,如表观遗传学、转录调控以及转录后调控等。在人膀胱移行细胞癌细胞系BLZ-211中,UCA1基因可转录生成三个有明显差异的转录本,分别命名为UCA1、UCA1a(CUDR)和UCA1b,长度依次为1400bp、2200bp和2700bp。目前已证实,转录本UCA1和UCA1a(CUDR)均属于LncRNA。其中,UCA1在膀胱癌细胞中被首次发现并报道与膀胱癌的发生发展密切相关,UCA1可与BRG1结合,拮抗BRG1结合到抑癌基因P21启动子区,从而促进膀胱癌5637细胞的增殖。UCA1在膀胱癌细胞以及组织中高表达,可通过cAMP/CREB途径影响PI3K-AKT依赖的信号转导通路,从而影响细胞周期。此外,UCA1在膀胱癌中的表达水平与病人耐药性以及预后密切相关,可作为膀胱癌诊断的肿瘤标记物。然而,UCA1a(CUDR)在膀胱癌细胞中参与调控的生物学功能及其机制的报道较少。以往的研究表明,UCA1a(CUDR)在各种人类肿瘤,包括膀胱癌、结肠癌、宫颈癌和肺癌等表达水平较高,与癌症的发生密切相关。已经证实U ...
