This observation suggests that FKBP12
This observation suggests that FKBP12.6-mediated signaling is linked to physiological, rather than pathological hypertrophy,24,25consistent with FKBP12.6-deficient mice never displaying heart failure, a common end stage for the pathological hypertrophic heart. To determine whether FKBP12.6-deficient males also develop exercise-induced cardiac arrhythmia and sudden death in addition to hypertrophy, we compared conscious ECG parameters in these mutant…
