Atrial Identity Is Determined by A COUP-TFII Regulatory Network (ChIP-Seq)


ABSTRACT: Embryonic cardiomyocytes possess the plasticity to choose between atrial and ventricular fates. For a limited window of time, the transcription factor COUP-TFII (Nr2f2) sufficiently and essentially confers the atrial identity through direct and indirect regulation of nearly half of chamber specific genes. Examination of COUP-TFII binding sites in embryonic artia

Atria and ventricles exhibit distinct molecular profiles that produce structural and functional differences between the two cardiac compartments. However, the factors that determine these differences remain largely undefined. Cardiomyocyte-specific COUP-TFII ablation produces ventricularized atria that exhibit ventricle-like action potentials, increased cardiomyocyte size, and development of extensive T tubules. Changes in atrial characteristics are accompanied by alterations of 2,584 genes, of  ...[more]
