A surgical mouse model of neonatal right ventricular outflow tract obstruction by pulmonary artery banding

Project description:Disease animal models play an extremely important role in preclinical research. Lack of corresponding animal models, many basic research cannot be carried out, and the conclusions obtained are incomplete or even incorrect. Right ventricular (RV) outflow tract (RVOT) obstruction leads to RV pressure overload (PO) and reduced pulmonary blood flow (RPF), which are two of the most important pathophysiological characteristics in pediatric cardiovascular diseases, and seriously affect the survival rate and long-term life quality of many children. Due to the lack of a neonatal mouse model for RVOT obstruction, it is largely unknown how RV PO and RPF regulate postnatal RV and pulmonary development. Thus, many treatment are directly applied from adults despite significant differences in cardiovascular physiology between infants and adults, with limited or even harmful results. Here we firstly introduced a neonatal mouse model of RVOT obstruction by pulmonary artery banding (PAB) on postnatal day 1. PAB induced neonatal RVOT obstruction, RV PO, and RPF. Neonatal RV PO induced cardiomyocyte proliferation, and neonatal RPF induced pulmonary dysplasia, the two features that can not be observed in adult RVOT obstruction. As a result, PAB pups exhibited overall developmental dysplasia, a sign similar to that of children with RVOT obstruction. Since many pediatric cardiovascular diseases are associated with RV PO and RPF, the introduction of neonatal mouse model of RVOT obstruction may greatly enhance our understanding of those diseases, and eventually save or improve the lives of many children. We used C57 mice in this study and divided them into sham and PAB group, each group contain 3 replicates.

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

Postnatal lung development under the influence of pulmonary hypoperfusion

Project description:We reported the RNAseq analyses of lungs tissues in neonatal SD rats with or without reduced pulmonary blood flow. Lung hypoperfution was induced by causing the supravalvular pulmonary stenosis through performing pulmonary artery banding surgery within 24 hours postnatally (P1). RNAseq analyses of the upper lobe of the right lung tissues was generated at P7 from 5 sham-operated rats and 4 pulmonary artery banding rats (1 rat dead before sample collection). The results revealed that there were 2666 differentially expressed genes between PAB and sham group at P7, among which 1255 were upregulated and 1411 were downregulated.

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).
