Activation of AMP-activated protein kinase stimulates Na+,K +-ATPase activity in skeletal muscle cells
Contraction stimulates Na+,K+-ATPase and AMP-activated protein kinase(AMPK)activity in skeletal muscle. Whether AMPK activation affects Na+,K+-ATPase activity in skeletal muscle remains to be determined. Short term stimulation of rat L6 myotubes with the AMPK activator 5-aminoimidazole-4-carboxamide- 1-β-D-ribofuranoside (AICAR), activates AMPK andpromotes translocation of the Na+,K +-ATPase α1-su
