Effect of volume overload on right ventricular remodeling in neonatal SD rats

We reported the RNAseq analyses of right ventricualr free wall myocardium in neonatal volume overload (VO) SD rat. VO was induced by the fistula between abdominal aorta and inferior vena cava (AVF) within 24 hours postnatally (P1). RNAseq analyses of RV free wall at P7 from VO and sham-operated rat revealed that there were 454 differentially expressed genes between VO and sham group at P7. GO analysis showed that in the VO and sham comparison, the upregulated genes mainly mediated immune system response and the downregulated genes mainly mediated apoptotic process at P7. VO has no effect to neonatal right ventricular cardiomyocyte proliferation.
