Multi-dimensional metabolomic remodeling under diverse muscle atrophic stimuli in vivo
Oyabu et al. establish a metabolomics dataset of muscle-atrophy-associated metabolites (“atrometabolites”) and identify impaired polyamine synthesis as a common feature of various muscle atrophy. The authors reveal that Amd1 and Amd2 genes play a pivotal role in maintaining polyamine metabolism and protein synthesis in muscle cells.
