TL;DR
This review discusses the potential of genome editing technologies, particularly CRISPR/Cas9, to correct mutations responsible for muscular dystrophies, such as Duchenne muscular dystrophy, which have been successfully amended in various animal models and human cells. The research highlights the promise of a one-time treatment approach that could restore normal gene expression in long-lived muscle tissues, addressing a critical gap in the development of curative therapies for these debilitating disorders.

Abstract
Muscular dystrophies are debilitating disorders that result in progressive weakness and degeneration of skeletal muscle. Although the genetic mutations and clinical abnormalities of a variety of neuromuscular diseases are well known, no curative therapies have been developed to date. The advent of genome editing technology provides new opportunities to correct the underlying mutations responsible for many monogenic neuromuscular diseases. For example, Duchenne muscular dystrophy, which is caused by mutations in the dystrophin gene, has been successfully corrected in mice, dogs, and human cells through CRISPR/Cas9 editing. In this Review, we focus on the potential for, and challenges of, correcting muscular dystrophies by editing disease-causing mutations at the genomic level. Ideally, because muscle tissues are extremely long-lived, CRISPR technology could offer a one-time treatment for muscular dystrophies by correcting the culprit genomic mutations and enabling normal expression of the repaired gene.

Key Findings
Research Background and Objectives
Muscular dystrophies are a group of genetic disorders characterized by progressive weakness and degeneration of skeletal muscle. Despite a thorough understanding of the genetic mutations and clinical manifestations associated with various neuromuscular diseases, effective curative therapies remain elusive. This review aims to explore the potential of genome editing technologies, particularly CRISPR/Cas9, to correct the genetic mutations responsible for these disorders, with a focus on Duchenne muscular dystrophy (DMD).
Main Methods/Materials/Experimental Design
The review primarily discusses the application of CRISPR/Cas9 genome editing in the context of muscular dystrophies. The methodology involves several key steps:
- Identification of Mutations: Recognizing specific genetic mutations in neuromuscular diseases, such as those in the dystrophin gene for DMD.
- CRISPR/Cas9 Design: Designing guide RNAs (gRNAs) that target the mutations for precise editing.
- Delivery Mechanisms: Employing various delivery systems to introduce the CRISPR components into muscle cells.
- Editing and Repair: Using CRISPR/Cas9 to induce double-strand breaks at the mutation sites, followed by cellular repair mechanisms to correct the mutations.
The following flowchart summarizes the technical approach:
Key Results and Findings
- Successful correction of mutations in animal models (mice and dogs) and human cells has been reported, demonstrating the feasibility of using CRISPR/Cas9 for gene therapy in muscular dystrophies.
- The potential for a one-time treatment is highlighted, given the long-lived nature of muscle tissues, which could sustain the corrected gene expression over time.
Main Conclusions/Significance/Innovation
The review underscores the transformative potential of CRISPR/Cas9 genome editing as a viable therapeutic approach for muscular dystrophies. By addressing the root genetic causes, this technology could lead to significant advancements in treatment, moving towards the possibility of permanent cures rather than symptomatic management. The innovation lies in the ability to achieve precise genomic corrections that restore normal gene function.
Research Limitations and Future Directions
- Limitations: The review acknowledges challenges such as off-target effects, efficiency of delivery methods, and the need for long-term studies to assess the durability of the gene edits.
- Future Directions: It suggests further research into optimizing delivery systems, improving the precision of CRISPR technology, and exploring the ethical implications of genome editing in humans.
