Project description:Bronchopulmonary dysplasia (BPD) is the major cause of chronic lung disease (CLD) and morbidity in preterm infants, which characterized by impaired pulmonary alveolar development in preterm infants. There is increasing evidence that micro RNA (miRNA) has a close association with the development of pulmonary diseasesincluding lung growth, pulmonary fibrosis, pneumonia, etc. The potential role of miRNA in the pathogenesis of BPD is unclear. This study aims to clarify the role of adrenomedullin (ADM) regulated by miRNA-547-3p during the process of BPD and illustrate the protective effect of ADM involved in preterm infants.We indentified the differential expressed miRNA and their potential target genes, microarray analysis using Agilent Human 4x44K Gene Expression Microarrays v2 and miRCURY LNA™ microRNA Array was performed. The results of miRNA chip were scanned by Axon GenePix 4000B and the signal of probes were read by GenePix Pro 6.0 software. Only the target genes which exist in both two databases and having different expression trend were remained. Thus, miRNA-574-3p and it’s target gene ADM were selected to do the further research in our study. And we verified miRNA-574-3p and ADM expression in BPD premature infants by realtime q-PCR. After the microarray expression analysis, there were 516 probes differential expressed between BPD samples and normal samples. Among them, 510 were up-regulated and 213 were down-regulated. Meanwhile, to the miRNA aspect, there were 37 up-regulated and 44 down-regulated. After text mining, we found ADM was already found play a role in BPD. ADM is an endogenous peptide with potent angiogenic, anti-oxidant, and anti-inflammatory properties. Realtime q-PCR assay results showed that, miRNA-574-3p expression level in blood samples from preterm infants with BPD was significantly decreased, ADM expression level in blood samples from preterm infants with BPD was significantly increased. In our study, we found that up-regulation of ADM regulated by miRNA-574-3p could protect preterm infants with BPD. These data provide novel insights into ADM regulated by miRNA-574-3p which may be shed light on BPD prevention and treatment.

Project description:Bronchopulmonary dysplasia (BPD) is a lung disease in premature infants characterized by impaired pulmonary development which persists into later life. While advances in neonatal care have improved survival rates of premature infants, cases of BPD haves been increased. Therapeutic options are limited for prevention and treatment. This study was designed to explore differentially expressed genes associated with BPD. Cord blood mRNA from preterm neonates that went on to develop BPD (n = 6) or not (nonBPD, n = 17) was applied to Illumina HumanHT-12 arrays, we identify differentially expressed genes associated with BPD.

Project description:We procured PBMCs whole blood from five HC preterm infants and five preterm infants with BPD. PBMCs were extracted using a density gradient centrifugation method. Initially, 10ml of peripheral blood was mixed with an equal volume of physiological saline, then carefully layered onto Ficoll solution (T10124, from Shangbao Biotech Co., Ltd., Shanghai). After centrifugation at 2,000 rpm for 20 minutes, the cells stratified due to differences in density, with PBMCs positioned between the red blood cells and plasma. Subsequently, the intermediate layer containing PBMCs was gently collected, washed several times with physiological saline to remove residual medium and red blood cells, and finally, PBMCs were isolated and collected through centrifugation.

Project description:Bronchopulmonary dysplasia (BPD) is a lung disease in premature infants characterized by impaired pulmonary development which persists into later life. While advances in neonatal care have improved survival rates of premature infants, cases of BPD haves been increased. Therapeutic options are limited for prevention and treatment. This study was designed to explore the relationship between gestational age (GA), birth weight and estímate blood cell-type composition in premature infants and to elucidate early epigenetic biomarkers associated with BPD. Cord blood DNA from preterm neonates that went on to develop BPD (n = 14) or not (nonBPD, n = 93) was applied to Illumina 450K methylation arrays. Using DNA methylation analysis of cord blood DNA, we investigated association of GA and birth weight with the estimated distribution of cord blood cell types, particularly the nucleated red blood cell (NRBC) in a pilot-size cohort of preterm infants with or without BPD. We describe changes in methylation-based estimates of blood cell-type composition in relation to GA and birth weight. After adjusting for covariates (GA, birth weight, cell type proportions, etc.) we identify differentially methylated CpGs and genes associated with BPD.

Project description:Tracheal aspirate (TAs) samples were collected from intubated preterm infants with hemodynamically significant intracardiac shunt (ICS), and a diagnosis of ICS-BPD/ICS-BPD-PH. 36 TA samples were analyzed. Small RNAs were extracted and the expression miRNAs was detected with PCR arrays.

This study was designed to explore the relationship between gestational age (GA), birth weight and estímate blood cell-type composition in premature infants and to elucidate early epigenetic biomarkers associated with BPD. Peripheral blood DNA (at days 14 and 28) from preterm neonates that went on to develop BPD (n = 14) or not (nonBPD, n = 93) was applied to Illumina EPIC methylation arrays. Using DNA methylation analysis of cord blood DNA, we investigated association of GA and birth weight with the estimated distribution of cord blood cell types, particularly the nucleated red blood cell (NRBC) in a pilot-size cohort of preterm infants with or without BPD. We describe changes in methylation-based estimates of blood cell-type composition in relation to GA and birth weight. After adjusting for covariates (GA, birth weight, cell type proportions, etc.) we identify differentially methylated CpGs and genes associated with BPD at different time points.
