Project description:The rate of cesarean delivery (CD) in China has risen sharply and the high rate was reported to be associated with increased risk of disease in the offspring. However, there is little research on the molecular mechanism of critical pathways and gene signatures involved in the neonatal immunity of cesarean-born infants. This study was undertaken to identify unique gene signatures which was involved in the neonatal immunity of cesarean-born infants through large-scale RNA-sequencing. Genes differentially expressed in cesarean-born infants were identified and further validated through quantitative real-time PCR (RT-qPCR). Moreover, we employed weighted gene co-expression network analysis (WGCNA) to identify highly connected genes that were correlated with neonatal inflammation. In total, 73 differentially expressed genes (DEGs) were identified between cesarean-born infants and normal vagina childbirth. The results obtained by secondary validation indicated that GATM, MIF, IFI27, IL1B, CA1, and EPHB1 were significantly upregulated in phenotype CD, while CYP2A6 and DLK1 were significantly down regulated. Further, functional and pathway enrichment analysis reveals perturbation of several DEGs involved in signaling pathways pertaining to immunoregulation, inflammation, apoptosis, and nervous development. Additionally, HLA-DOB popped out as a core gene in the process of inflammation, which might indicate the risk of cesarean-born infants for inflammatory disease. Notably, our study for the first time has documented gene signatures PIK3CA, PTPRC, SOS1, IL6ST, and MALT1, which were found to be involved in neonatal inflammation. Taken together, the full expression repertoire including the differentially expressed gene sets and core differentially co-expressed genes should provide an excellent resource for identifying potential biomarkers of cesarean-born infants with inflammation, and formulating new hypotheses for physiological functions and the discovery of novel therapeutic targets for inflammatory disease.
