Myh6-Cre targets some other organs outside the heart and affects the expression of endogenous Myh6 in heart. a tdTomato was detected in some other organs from the adult Myh6-Cre/ + ;R26-tdTomato/ + mice at P8W. 3 mouse samples were examined. b ECG analyses of the P8W hearts with indicated genotypes. n = 6 mice per group. LVESD, left ventricular end-systolic dimension; LVEDD, left ventricular end-diastolic dimension; ESV, end-systolic volume; EDV, end-diastolic volume; EF, ejection fraction; FS, fractional shortening. c Whole bodies of the mice with indicated genotypes at P8W. d Whole-mount view of the hearts with indicated genotypes at P8W. e The relative heart weight was increased in the Myh6-Cre/Cre mice at P8W. HW, heart weight. BW, body weight. f HE staining shows the thinner left ventricular wall and ventricular septum in the hearts of Myh6-Cre/Cre mice at P8W. g WGA staining on heart sections. h The expression level of Myh6 in the adult hearts at P8W. n = 3 mice per group in (ch). White scale bars, 5 mm; Black scale bars, 2 mm; Red scale bars, 200 µm; Yellow scale bars, 100 µm. NS, non-significant; *p < 0.05; ***p < 0.001
