Disruption of the complex network that regulates redox homeostasis often underlies resistant phenotypes, which hinder effective and long-lasting cancer eradication. In addition, the RNA methylome-dependent control of gene expression also critically affects traits of cellular resistance to anti-cancer agents. However, few investigations aimed at establishing whether the epitranscriptome-directed adaptations underlying acquired and/or innate resistance traits in cancer could be implemented through the involvement of redox-dependent or -responsive signaling pathways. This is unexpected mainly because: i) the effectiveness of many anti-cancer approaches relies on their capacity to promote oxidative stress (OS); ii) altered redox milieu and reprogramming of mitochondrial function have been acknowledged as critical mediators of the RNA methylome-mediated response to OS. Here we summarize the current state of understanding on this topic, as well as we offer new perspectives that might lead to original approaches and strategies to delay or prevent the problem of refractory cancer and tumor recurrence.
调控氧化还原稳态的复杂网络的破坏常常是耐药表型的基础,这阻碍了有效和持久的癌症根除。此外,RNA 甲基化组依赖性的基因表达调控也严重影响细胞对抗癌药物的耐药性特征。然而,很少有研究旨在确定在癌症中获得性和/或固有耐药性特征的表观转录组指导的适应性是否可以通过涉及氧化还原依赖或响应的信号通路来实现。这是出乎意料的,主要是因为:i)许多抗癌方法的有效性依赖于其促进氧化应激(OS)的能力;ii)氧化还原环境的改变和线粒体功能的重编程已被认为是 RNA 甲基化组对 OS 反应的关键介质。在这里,我们总结了这一主题的当前理解状态,以及我们提供的新视角,这些视角可能会导致延迟或预防难治性癌症和肿瘤复发问题的新方法和策略。
