Effects of ouabain and CGP-37157 on [Ca2+]c cycling. Isolated cardiac myocytes were loaded with indo-1 AM. After 5 min treatment of 100nM isoproterenol with or without ouabain and CGP-37157, cells were field stimulated for 3 min. A) Representative [Ca2+]c traces at the beginning (left panels) and end of stimulation (right panels). B) The average Δ[Ca2+]c recorded at the midpoint of stimulation was is shown for control cells (n=3), ouabain treated cells (n=12), and ouabain plus CGP-37157 treated cells (n=12). * p<0.01 while compared to control; † p<0.05 while compared to ouabain treated group. C) The average of diastolic [Ca2+]c recorded in control (isoproterenol only), ouabain-treated, and ouabain plus CGP-37157 -treated cells.
