PKA but not CAMKII mediates BPA-induced SR Ca2+ leak in female rat ventricular myocytes. A and D, Effect of PKA blockade with PKI and CAMKII blockade with AIP, respectively, on BPA-induced increase in diastolic Ca2+ sparks. B and E, Average Ca2+ spark frequency. cont, control. C and F, Average Ca2+ spark amplitude under indicated treatments. Data are averages of total 128 sparks from 10 myocytes for B and C and 206 sparks from 22 myocytes for E and F (n = 6 hearts). BPA = 1 nM for all experiments; PKI, H89, AIP, and KN93 concentration = 1 μM. *, P < .05 vs control. N.S, not significant (P > .5).
