- Myotonic dystrophy type 1 (DM1) is a severe neuromuscular disorder caused by a (CTG)n repeat expansion in the DMPK gene.
- The study investigates the impact of DM1 on myogenesis by analyzing RNA expression during differentiation of DM1 and corrected myoblast cell lines.
- Proliferating myoblasts showed mild RNA phenotype, but differentiation led to significant increases in differentially expressed genes and aberrant splicing.
- Aberrant splicing during differentiation affected genes related to muscle function, organization, contraction, and cell junctions.
- The findings emphasize the critical role of differentiation and MBNL1-dependent splicing in the DM1 RNA phenotype.
