miRNA expression data from neonatal rat ventricular myocytes (NRVM) silenced for KChIP2

Loss of KChIP2 during cardiac stress has been suggested to have a transcriptional impact on cardiac ion channels through altered miRNA activity, contributing to maladaptive electrical remodeling. Therefore, we tested the consequence of KChIP2 loss, in the absence of cardiac stress, by treating cultured neonatal rat ventricular myocytes with siRNA for KChIP2 and subsequently performed miRNA microarray analysis to identify up-regulation of potential miRNA targets.
