Data are mean ± SEM. W, wild-type mice; K, FKBP12.6 overexpressing mice; S, sham-operated; TAC, thoracic aortic constriction; F, female; M, male; C, noncongested mice; H, mice with congestive heart failure; BW, body weight; LVW; left ventricle weight; HW/TL, ratio heart weight to tibia length; Lu/TL, ratio lung weight to tibia length. *P < 0.05 TAC versus sham; $P < 0.05 C versus H mice; †P < 0.05 female versus male.
