Current genome-wide studies have indicated that a great number of long non-coding RNAs (lncRNAs) are transcribed from the human genome and appeared as crucial regulators in a variety of cellular processes. Many studies have displayed a significant function of lncRNAs in the regulation of autophagy. Autophagy is a macromolecular procedure in cells in which intracellular substrates and damaged organelles are broken down and recycled to relieve cell stress resulting from nutritional deprivation, irradiation, hypoxia, and cytotoxic agents. Autophagy can be a double-edged sword and play either a protective or a damaging role in cells depending on its activation status and other cellular situations, and its dysregulation is related to tumorigenesis in various solid tumors. Autophagy induced by various therapies has been shown as a unique mechanism of resistance to anti-cancer drugs. Growing evidence is showing the important role of lncRNAs in modulating drug resistance via the regulation of autophagy in a variety of cancers. The role of lncRNAs in drug resistance of cancers is controversial; they may promote or suppress drug resistance via either activation or inhibition of autophagy. Mechanisms by which lncRNAs regulate autophagy to affect drug resistance are different, mainly mediated by the negative regulation of micro RNAs. In this review, we summarize recent studies that investigated the role of lncRNAs/autophagy axis in drug resistance of different types of solid tumors.
目前的全基因组研究表明,大量的长非编码 RNA(lncRNA)是从人类基因组中转录而来的,它们在各种细胞过程中表现出重要的调节作用。许多研究表明,lncRNA 在自噬的调节中具有重要的功能。自噬是细胞内的一种大分子过程,其中细胞内的底物和受损的细胞器被分解并回收,以缓解由于营养剥夺、辐射、缺氧和细胞毒性药物引起的细胞应激。自噬可以是一把双刃剑,根据其激活状态和其他细胞情况,在细胞中发挥保护或损伤作用,其失调与各种实体瘤的肿瘤发生有关。各种治疗方法诱导的自噬已被证明是对抗癌药物产生耐药性的独特机制。越来越多的证据表明,lncRNA 通过调节各种癌症中的自噬在药物耐药性中起重要作用。lncRNA 在癌症耐药性中的作用存在争议;它们可能通过激活或抑制自噬来促进或抑制耐药性。lncRNA 调节自噬以影响耐药性的机制不同,主要是通过负调控 microRNA 来介导的。在这篇综述中,我们总结了最近的研究,这些研究调查了 lncRNA/自噬轴在不同类型实体瘤的耐药性中的作用。
