Figure 5. PLB-dependent effects of 10 μmol/L SIN-1 and 200 μmol/L SIN-1 on β-adrenergic stimulated myocyte contractility.

Figure 5

Pooled data (mean±S.E.M.) expressed as a % Δ from control (Basal) or a % Δ from ISO (0.01 μmol/L ISO, 1 μmol/L ISO) demonstrating the positive effect of 10 μmol/L SIN-1 (open circles) and the negative effect of 200 μmol/L SIN-1 (closed circles) during varying levels of β-adrenergic stimulation for both myocyte shortening (top panel) and [Ca2+]i transients (bottom panel). NOTE: 200 μmol/L SIN-1 data (closed circles) have been published previously in a different form [13].
