Experimental animal groups. The cardiac left ventricle from mice of both genders (n = 24) and genotypes (n = 24) were studied at 30 days postsurgery. Symbols used for genotypes are W (wild type) and K (mice overexpressing FKBP12.6), and for genders F (female) and M (male), sham-operated mice without banding (S) and mice having undergone thoracic aortic constriction (T for TAC). Due to the presence of pulmonary edema, two distinct TAC groups were defined as follows: without [noncongested mice, (C)] or with lung congestion [mice with congestive heart failure, (H)].
