長鏈非編碼RNA H19在食管鱗癌中的表達(dá)水平及其臨床預(yù)后相關(guān)性的研究
發(fā)布時間:2021-07-06 07:12
食管癌是最致命的惡性腫瘤之一。它是導(dǎo)致腫瘤死亡的第六大原因,也是世界上第八大最常見的腫瘤。主要是因為它極難早期診斷,侵襲能力強,因此預(yù)后差以及存活率低。其五年存活率約為15%-25%。更糟糕的是,隨著世界范圍內(nèi)人口老齡化的增長,食管癌的發(fā)病率也正在逐年上升。中國是食管癌發(fā)病率最高的地區(qū)之一,尤其以中國河南省安陽市最高。長鏈非編碼RNA(long non-coding RNA,lncRNA)為長度大于200個核苷酸,不具有編碼蛋白功能的RNA分子。報道表明,它可以通過與DNA、染色質(zhì)、蛋白質(zhì)、RNA等大分子相互作用促進或抑制腫瘤的發(fā)生、侵襲和轉(zhuǎn)移,其復(fù)雜的作用機制是目前研究的重點和難點。據(jù)報道,LncRNAH19在成人組織中表達(dá)量低或不表達(dá),但在多種腫瘤中高表達(dá),如大腸癌、乳腺癌、膀胱癌等,且與腫瘤的發(fā)生發(fā)展密切相關(guān)。因此LncH19有可能具有腫瘤早期診斷和預(yù)后判斷的標(biāo)志物的臨床價值。本課題大規(guī)模地使用ISH方法檢測食管鱗癌中H19的表達(dá)水平,旨在探討其在食管癌中的臨床病理作用。其次運用生物信息學(xué)分析方法預(yù)測LncRNA H19的靶向miRNA,探討H19在食管鱗癌中可能的作用機制。方法...
