Acute Electrical Pulse Stimulation and Hyperglycemia Regulates RCAN1-4 in C2C12 myotubes through Oxidative Stress.

Regulator of Calcineurin1 (RCAN1) controls the Sr/Thr phosphatase, Calcineurin. RCAN1 has never been studied in-vitro in myotubes following acute Electrical Pulse Stimulation (EPS) which recapitulates the physiological effect of exhaustive exercise and hyperglycemia (HG). 144 h differentiated C2C12 myotubes were treated either with high glucose (HG) at 15mM or kept as control for 48 h.
