Effects of ISO and 3mM [Ca2+]o on WT and NOS1−/− PLB Serine16 phosphorylation and Ca2+ transient decline in NOS1−/− myocytes. A) Summary data (mean±sem) of PLB Serine16 phosphorylation with ISO or 3mM [Ca2+]o (A.U.- arbitrary units). B) Summary data (mean±sem) of the ISO mediated increase in PLB Serine16 phosphorylation expressed as the % of 3mM [Ca2+]o. Summary data (mean±sem) of Ca2+ transient amplitude (left) and decline (right) in NOS1−/− myocytes which had a higher maximal Ca2+ transient amplitude to ISO (C) or 3 mM [Ca2+]o (D). *P<0.05) vs corresponding WT or 3 mM [Ca2+]o. E) Individual values of peak [Ca2+]i versus RT50 with Ca2+ (black, r2=0.70) and ISO (gray, r2=0.007).
