Abstract:
Among various dominantly inherited spinocerebellar ataxias (SCAs), it is revealed that the molecular mechanism of so called "non-coding microsatellite repeat expansion disorders" was involved in RNA gain-of-function as well as "RAN translation". Recently, the "polyglutamine disorders" caused by the coding CAG repeat expansions were also clarified that they were involved in RNA mechanism or RAN translation. The common molecular mechanism might exist between SCAs of which the repeat expansions were located in both coding and non-coding regions.

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
