Effect of H89 on TE-induced intracellular Ca2+ increase in isolated mouse cardiomyocytes. The PKA inhibitor H89 was preincubated for 5 min with the cardiomyocytes followed by 60 μg/ml TE administration with or without 1.8 mM extracellular Ca2+. a. The representative fluorescent Ca2+ scanning images of cardiomyocytes affected by H89 on TE-induced intracellular Ca2+ increase. b. The traces of F/F0 values affected by H89 on TE-induced intracellular Ca2+ increase (n = 6). Data are shown by mean ± SD (n = 6)
