Decoding the transcriptome of denervated muscle at single-nucleus resolution

Skeletal muscle exhibits remarkably plasticity under both physiological and pathological conditions. We used adult mice with sciatic denervation as model of muscle atrophy. SnRNA-seq was performed to generate single-nucleus transcriptome profiles of gastrocnemius from normal and denervation mice. Our results define the myonuclear transition, metabolic remodeling and gene regulation networks associated with muscle atrophy induced by denervation and illustrated the molecular basis of heterogeneity and plasticity of muscle cells in response to muscle atrophy, thus providing a resource for exploring molecular mechanisms leading to muscle atrophy Single-nucleus RNA-seq in normal and denervated mice.
