A nucleolar view of neuromuscular disease.

The nucleolus is a master regulator of ribosome biogenesis and cellular homeostasis, as well as an increasingly key determinant of neuromuscular diseases. Across these conditions, diverse genetic and molecular lesions converge on alterations in nucleolar organization and function. These changes impact ribosomal RNA synthesis and reshape translational output, linking nuclear events to cytoplasmic protein homeostasis in disease-relevant contexts. In this review, we propose a comprehensive framework in which the nucleolus integrates RNA dysfunction, genome organization, and translational control across neuromuscular disorders. This perspective provides a conceptual basis for interpreting disease heterogeneity and highlights nucleolar pathways as potential, underexploited targets for therapeutic intervention.
