Effect of cardiomyocyte specific KO of AKT1, AKT2, and AKT1 + AKT2 on gene expression profile of the heart

ABSTRACT: In the mammalian heart AKT1 and AKT2 are the isoforms of the protein kinase AKT (protein kinase B) which are predominantly expressed. AKT isoforms exert common and specific functions in the field of metabolism, cellular growth, apoptosis and cell migration. To identify specific and common functions of AKT1 and AKT2 isoforms, we generated tamoxifen-inducible, cardiomyocyte-specific AKT1, AKT2, and AKT1+AKT2 double knockout mice (iCMAKT – KO mice). Inactivation of AKT isoforms was achieved by application of 4-OH-tamoxifen, which activates an OH-Tx inducible cre-recombinase expressed under the control of the αMHC-promoter (αMHC-mercremer). Transgenic mice expressing only the αMHCmercremer construct were also treated with OH-Tx and served as controls. To identify alterations in cardiac gene expression due to AKT deletion we analyzed gene expression profiles of control hearts, iCMAKT1, iCMAKT2 and iCMAKT1+2 hearts.
