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 treated 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.

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.

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.

Project description:Pulmonary hypertension is a frequent consequence of left heart disease and congestive heart failure (CHF) and causes extensive lung vascular remodelling which leads to right ventricular failure. Functional genomics underlying this structural remodelling are unknown but present potential targets for novel therapeutic strategies. We used microarrays to detail the gene expression underlying vascular remodeling in the pathogenesis of pulmonary hypertension and identified distinct classes of up-regulated genes during this process. Control rat lung samples were compared to samples of aortic banding rat lungs which exhibit pulmonary hypertension

Project description:We reported the RNAseq analyses of pulmonary vein tissues at the age of postnatal day 21 (P21) on SD rats with or without pulmonary vein stenosis. Pulmonary vein stenosis was induced by performing pulmonary vein banding surgery within 24 hours postnatally. RNAseq analyses of the pulmonary vein tissues was generated at P21 from 3 sham-operated rats and 3 pulmonary vein banding rats. The results revealed that there were 1124 differentially expressed genes between PAB and sham group at P7, among which 714 were upregulated and 410 were downregulated.

Project description:To assess in order to assess potential disparities in gene expression due to developmental differences we performed a comparison between hippocampus and heart tissues from rat and mouse pup (one week old) and adult (10 week old) animals. Using heart and hippocampal tissue from mouse (C57BL/6) and rat (Sprague Dawley) we investigate via microarrays, gene expression divergence at the tissue level between a Brain and a Non-brain tissue. We also investigated any developement difference in gene expression between pups and adult animals. For the pups samples we used 3 biological replicates and for the adult samples we used 2 biological replicates with 2 technical replicates for each.
