“… caffeine … cyclosporin A (CsA) and KN93, whereas cardiomyocyte hypertrophy induced by Ang II was inhibited by KN93, but not CsA. Our results show that cardiomyocyte hypertrophy … activity, contractile performance and signaling pathways of CaMKII and/or calcineurin, whereas the Ca2+ overload is not sufficient to cause the cardiomyocyte hypertrophy.”
