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

Project description: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.

The difference of right and left ventricular remodeling caused by volume overload in neonatal SD rats

Project description:We reported the RNAseq analyses of right ventricle (RV) and left ventricle (LV) in neonatal volume overload (VO) and sham-operated 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 and LV free wall of P7 from VO and sham-operated rat. It demonstrated that the 1806 differentially expressed genes (DEGs) between RV and LV at the neonatal stage were primarily enriched in GTPase mediating signal transduction, insulin signaling pathway and thyroid hormone signaling pathway. VO produced 3 more times DEGs in LV than RV . GO analysis of these DEGs demonstrated that in the top 150 enriched terms, the LV comparison and RV comparison shared 34 terms (22.7%) in common. These commonly enriched terms were primarily associated with GTPase mediating signal transduction. KEGG analysis of these DEGs demonstrated that in the top 30 enriched terms, the LV comparison and RV comparison shared 14 terms (46.7%) in common. And insulin signaling pathway and thyroid hormone signaling pathway are the top two enriched terms in common. Regarding the differently enriched GO terms, they were primarily associated with lipid metabolism and ion channel in RV and primarily associated nucleic acid metabolism in LV. The top two differently enriched KEGG terms were arrhythmogenic right ventricular cardiomyopathy (ARVC) and adipocytokine signaling pathway in RV while microRNAs in cancer and longevity regulating pathway in LV. These results were further confirmed by the determination of metabolites.

Cyclosporin ameliorates right ventricular remodeling of postnatal mice with volume overload.

Project description:We reported the RNAseq analyses of right ventricular free wall of myocardium in three groups of mice（3 in each group）at postnatal day 14 (P14). The mice in volume overload (VO) group underwent an abdominal surgery by puncture from aorta to inferior vena cava at P7, mice in Sham group underwent the same surgery except for the puncture. The mice in CsA group were VO mice who were also injected with cyclosporin A(CsA) for seven days. The results revealed that there were differentially expressed genes between VO and sham group at P14, Inhibiting the immune response with CsA caused the gene expression profile of VO mice to shift towards that of sham mice.

Effect of neonatal right ventricular pressure overload on gene expression and regions of open chromatin during postnatal heart development

Project description:To investigate the effect of pressure overload (PO) during postnatal right ventricular (RV) development, we established the RV PO model by conducting pulmonary artery banding (PAB) surgery on neonatal Sprague-Dawley (SD) rats. We then performed gene expression and chromatin openness profiling analysis using data obtained from RNA-seq and ATAC-seq of RV free walls from PO and sham-operated rats at postnatal day 21 (P21).

Right ventricular failure due to pulmonary banding

Project description:Right ventricular failure was induced thourgh pulmonary banding in 11 pigs. Right ventricular failure was defined as a SRVP >50 mmHg during two hours. After right ventricular failure was induced, half the pigs were treatmed with a Glenn-shunt combined with pulmonary banding for one hour, and the other half served as control group with pulmonary banding only. The aim was to study the change in global gene expression during right ventricular failure due to pulmonary banding, and the effect of volume unloading during pulmonary banding. 11 pigs. Samples at the following time periods: 1) Baseline 2) Right ventricular failure 3) Treatment with modified Glenn-shunt/Control. After Right ventricular failure, pigs were divided into two groups a) Treatment with modified Glenn-shunt or b) Control group
