摘要
癌症是世界第二大死因。最常见的癌症治疗方法是手术、放疗和化疗。耐药、上皮-间充质转化(EMT)和转移是当今癌症治疗的紧迫问题。越来越多的证据表明,耐药与EMT之间存在着密切的联系。的确,耐药癌细胞具有更强的EMT和侵袭能力。最近的研究表明,lncRNAs(长链非编码RNAs)是一种非编码转录本,在不同癌症的EMT、转移和耐药调控中发挥重要作用。然而,lncRNAs与EMT和耐药性之间的关系尚不清楚。这些作用可能通过多种信号通路发挥作用,如TGF-β、PI3K-AKT和Wnt/β-catenin。确定lncRNAs在这些途径和过程中的关键调控作用,将有助于开发新的靶向治疗方法。我们综述了与EMT和治疗耐药相关的lncRNAs的关键方面。我们关注lncRNAs与影响EMT和耐药的分子信号通路之间的串扰。此外,上述每种lncRNAs都可作为癌症的潜在诊断、预后和治疗耐药指标。然而,lncRNAs的临床应用研究仍存在一些挑战。
