Research Abstract

To address the mechanisms underlying muscle atrophy, we produced three different mouse atrophy models by disuse and denervation. In these models, transcriptome analysis reveled that the drastic changes of chromatin remodeling factors and cell cycle regulators were observed at the acute phase, indicating that muscle atrophy is the active rather than passive cellular responses. In addition, epigenetic regulation of the satellite cell is essential for the muscle regeneration after injury and atrophy.
