  • Striated muscle-specific disruption of the dystroglycan (DAG1) gene results in loss of the dystrophin-glycoprotein complex in differentiated muscle and a remarkably mild muscular dystrophy with hypertrophy and without tissue fibrosis. We find that satellite cells, expressing dystroglycan, support continued efficient regeneration of skeletal muscle along with transient expression of dystroglycan in regenerating muscle fibers. We demonstrate a similar phenomenon of reexpression of functional… CONTINUE READING
