Duchenne's muscular dystrophy (DMD) is a severe X-linked disorder characterized by progressive muscle degeneration, leading to loss of ambulation, respiratory failure, and premature death. It affects approximately 1 in 3,500 live male births and is caused by mutations in the dystrophin gene, which impairs muscle fiber stability. Current treatments are limited to managing symptoms and slowing disease progression, with no curative therapies available. The advent of CRISPR/Cas9 gene-editing technology has introduced a promising approach for directly correcting the genetic mutations responsible for DMD. This review explores the potential of CRISPR/Cas9 as a transformative therapy for DMD, highlighting its successes in preclinical models, the challenges associated with its delivery, and the obstacles to its clinical application. While preclinical studies demonstrate the efficacy of CRISPR/Cas9 in restoring dystrophin expression and improving muscle function, significant hurdles remain, including optimizing delivery methods and ensuring long-term safety.
杜兴氏肌肉营养不良症(DMD)是一种严重的X连锁疾病,其特征是进行性肌肉退化,导致无法行走、呼吸衰竭和过早死亡。它影响约每3500例活产男婴中的1例,由肌营养不良蛋白基因突变引起,该突变损害肌肉纤维稳定性。目前的治疗仅限于控制症状和减缓疾病进展,尚无治愈性疗法。CRISPR/Cas9基因编辑技术的出现引入了一种有前景的方法,可直接纠正导致DMD的基因突变。本综述探讨了CRISPR/Cas9作为DMD变革性疗法的潜力,强调了其在临床前模型中的成功、与递送相关的挑战以及其临床应用的障碍。虽然临床前研究证明了CRISPR/Cas9在恢复肌营养不良蛋白表达和改善肌肉功能方面的疗效,但仍存在重大障碍,包括优化递送方法和确保长期安全性。
