肌强直性营养不良症(DM1)是最常见的成人肌肉营养不良症,是一种多系统,常染色体显性遗传疾病,由CTG重复扩增导致突变RNA的核保留和随后的RNA毒性引起。对RNA毒性的分子机制的重大见解已经导致了治疗DM1的令人惊讶的可能性是一个可行的前景。在这篇综述中,我们简要介绍了DM1的临床情况,并描述了在了解DM1 RNA毒性发病机制的研究如何在疾病发病的各个步骤中导致有针对性的治疗方法的开发。我们将重点讨论基于rna的治疗方法和小分子疗法的前景和当前的局限性。最后,我们讨论了临床工具和结果测量的未满足需求,这是在临床试验中评估这些潜在疗法的必要先决条件。
Myotonic dystrophy (DM1), the most common adult muscular dystrophy, is a multi-system, autosomal dominant genetic disorder caused by an expanded CTG repeat that leads to nuclear retention of a mutant RNA and subsequent RNA toxicity. Significant insights into the molecular mechanisms of RNA toxicity have led to the surprising possibility that treating DM1 is a viable prospect. In this review, we briefly present the clinical picture in DM1, and describe how the research in understanding the pathogenesis of RNA toxicity in DM1 has led to targeted approaches to therapeutic development at various steps in the pathogenesis of the disease. We discuss the promise and current limitations of each with an emphasis on RNA-based therapeutics and small molecules. We conclude with a discussion of the unmet need for clinical tools and outcome measures that are essential prerequisites to proceed in evaluating these potential therapies in clinical trials.
