cardiovascular system

• neonatal adeno-associated virus-mediated delivery of Tarbp2 or transgenic expression of Mir208a suppresses chamber dilation, permits normal cardiac morphology and restores viability as does knockdown of Sox6, while Tnnt2-dirven viral-mediated overexpression of Sox6 recapitulates the phenotype of cardiac conditional null Tarbp2
