Inhibition of Cav1.3 Ca2+ channels decreased spontaneous Ca2+ transient rate under β-adrenergic stimulation in isolated Cav1.2DHP−/− SANC. Line-scan and corresponding time-course of Ca2+ fluorescence in dormant (A) and spontaneously firing (C) Cav1.2DHP−/− SANC in Tyrode, ISO (100 nM) and ISO + Nife (3 µM) conditions. Average Ca2+ transient rate, mean coefficient of variation and mean diastolic calcium in dormant ((B), blue, n = 16) and firing ((D), red, n = 11) Cav1.2DHP−/− SANC. * p < 0.05, ** p < 0.01, *** p < 0.001 by parametric one-way ANOVA or non-parametric Friedman test.
