Calcineurin in human heart hypertrophy.
BACKGROUND In animal models, increased signaling through the calcineurin pathway has been shown to be sufficient for the development of cardiac hypertrophy. Calcineurin activity has been reported to be elevated in the myocardium of patients with congestive heart failure. In contrast, few data are available about calcineurin activity in patients with pressure overload or cardiomyopathic hypertro...
متن کاملCalcineurin signaling in human cardiac hypertrophy.
The initial observation in 19981 that calcineurin, a calmodulin-dependent protein phosphatase, is capable of driving cardiac hypertrophy, heart failure, and death in experimental animal models received special attention for several reasons. Previous evidence suggested that dysregulation of calcium metabolism is an integral feature of stresses that promote hypertrophy, and calcineurin was known ...
متن کاملCalcineurin signalling mechanisms in myocardial hypertrophy
Calcineurin dephosphorylates multiple serine residues near the N terminus of NFAT proteins enabling them to translocate from cytoplasm to nucleus, where they activate a subset of hypertrophic response genes. Transgenic mice over-expressing a constitutively active form of calcineurin or NFAT3, developed obviously hypertrophy and heart failure or sudden death proving its pathogenic role. Here we ...

متن کاملCalcineurin inhibitor attenuates left ventricular hypertrophy, leading to prevention of heart failure in hypertensive rats.
BACKGROUND There is controversy regarding the contribution of calcineurin activation to the development of pressure-overload left ventricular (LV) hypertrophy and heart failure. The aim of this study was to explore whether the inhibition of calcineurin may prevent the transition to heart failure in hypertensive rats and, if so, to clarify in which developmental stage of LV hypertrophy calcineur...
