Gene expression of skeletal muscles in response to overexpression of Notch1 intracellular domain (N1ICD)


ABSTRACT: Analysis of gene expression profile of Tibialis anterior (TA) skeletal muscle tissues with Notch1 intracellular domain (N1ICD) overexpression. Skeletal myogenesis involves sequential activation, proliferation, self-renewal/differentiation and fusion of myogenic stem cells (satellite cells). Notch signaling is known to be essential for the maintenance of satellite cells, but its function in late-stage myogenesis, i.e. post-differentiation myocytes and post-fusion myotubes, is unknown. Here we use muscle creatine kinase (MCK)-Cre to induce N1ICD expression in multinucleated myotubes. We found that myotube-specific Notch1 activation improved muscle regeneration and exercise performance of mdx mice, a model of Duchenne Muscular Dystrophy (DMD). Agilent microarray was performed to compare gene expression in mdx control and N1ICD-overexpressing mdx muscles. The results may provide mechanistic insights into how Notch1 activation in myotubes modulate muscle function.
