pubmed:abstractText |
Nkx2.5 is a conserved homeodomain (HD) containing transcription factor essential for early cardiac development. We generated a DNA nonbinding missense mutation, I183P in the HD, similar to the missense HD mutation found in patients. Transgenic mice expressing this mutation under beta-MHC promoter [beta-MHC(I183P)] showed a postnatal lethal phenotype with heart failure. In contrast, mice expressing the mutation under alpha-MHC promoter [alpha-MHC(I183P)] survive, with later onset heart failure. The aim of this study was to investigate the interrelationship between lethal cardiac failure and the electrophysiologic (EP) phenotypes using cardiac-specific promoters with mutant gene expression at different stages of development and maturation.
