翻译和信使核糖核酸周转的相互作用帮助揭示了基因表达调控是一个连续体,在这个连续体中,转录本在细胞核中“诞生”期间发生的事件可以对细胞质中的后续步骤产生深远的影响。这一连续体的例子是无意义介导的信使核糖核酸衰变(NMD),即过早终止密码子影响翻译和信使核糖核酸衰变的过程。对NMD的研究帮助我们提出了治疗概念,即用单一的小分子药物治疗因无义突变而患有多种遗传疾病的患者子集,这种药物可以调节过早的无义密码子的翻译终止过程。在这里,我们回顾了翻译终止和NMD,以及我们在过去15年中做出的导致阿托鲁仑的鉴定、表征和临床测试的后续努力,阿塔鲁仑是一种新的治疗方法,具有治疗由无义突变引起的广泛遗传疾病的潜力。
The interplay of translation and mRNA turnover has helped unveil how the regulation of gene expression is a continuum in which events that occur during the “birth” of a transcript in the nucleus can have profound effects on subsequent steps in the cytoplasm. Exemplifying this continuum is nonsense-mediated mRNA decay (NMD), the process wherein a premature stop codon affects both translation and mRNA decay. Studies of NMD helped lead us to the therapeutic concept of treating a subset of patients suffering from multiple genetic disorders due to nonsense mutations with a single small molecule drug that modulates the translation termination process at a premature nonsense codon. Here we review both translation termination and NMD, and our subsequent efforts over the last fifteen years that led to the identification, characterization, and clinical testing of ataluren, a new therapeutic with the potential to treat a broad range of genetic disorders due to nonsense mutations.
