Figure 4. 200 μmol/L SIN-1 increases PLB−/− myocyte submaximal β-adrenergic responsiveness.

Figure 4

A.) Individual, steady-state shortening (top) and [Ca2+]i transient (bottom) traces representing the positive effect of 200 μmol/L SIN-1 on PLB−/− myocyte submaximal β-adrenergic responsiveness. B.) Pooled data (mean±S.E.M.) demonstrating the effect of ISO (0.01 μmol/L, clear bar) and ISO+SIN-1 (200 μmol/L, filled bar) on shortening (top) and [Ca2+]i transients (bottom) in PLB−/− myocytes. *p<0.05 vs. ISO.
