OH-Txf causes efficient gene deletion in floxed αMHC-MerCreMer mice. Representative western blots and summarized data of a Akt1 and Akt2, b GSK-3β, and c p38 of hearts from iCM-Akt1/2KO, iCM-GSK3βKO, and iCM-p38KO mice, respectively, are shown. Cardiomyocyte restricted gene deletion was initiated by intraperitoneal application of 20 mg/kg OH-Txf on 5, 7 or 10 consecutive days as indicated. d Representative immunofluorescence stainings of cross sectioned (upper panel) and longitudinal slices (lower panel) of hearts from iCM-Akt1/2 knock out mice (KO) or WT mice are shown. Administration of 20 mg/kg OH-Txf for five consecutive days resulted in loss of both Akt1 (left panel) and Akt2 (right panel) in cardiomyocytes. Data are normalized to WT values and presented as mean ± SD. *p < 0.05 vs WT (unpaired, two-tailed student’s T-test)
