myoblast cell. Isoform Neu2 mRNA and enzymatic activity are significantly increased in hypertrophic myofibers. Constitutive activation of AKT or Igf-1 treatment as well as treatment with vasopressin or trichostatin results in rise in Neu2 activity. Myofiber atrophy obtained by dexamethasone treatment or starvation triggers a significant loss of Neu2 activity and is paralleled by downregulation of Neu2 transcript levels
