Repair, Degradation, and Calcium Regulation in Muscle Project

Project Leader: Diana J. Bigelow

  • Identify mechanisms of repair of nitrated SERCA2a in myocytes following its modification by acute and chronic exposure to peroxynitrite.
  • Compare the identity of myocyte proteins nitrated by chronic PN exposure by SIN-1 and by inflammatory cytokines with those of aging skeletal muscle.
  • Identify cellular mechanisms of repair of PN-induced oxidative modifications of cysteines and methionines, in SERCA2a in relationship with those of the total cellular proteome.
