摘要:Background Pulmonary arterial hypertension (PAH) is a deadly disease, and the molecular mechanism of PAH has not been clarified clearly. The objective of this study was to identify possible biomarkers and explore the potential mechanisms of Schistosoma-induced PAH.; Methods GSE49114 RNA-Seq data developed from mouse whole lung tissues were downloaded from the Gene Expression Omnibus database. Differentially expressed genes (DEGs) between control samples and schistosomiasis-induced PAH samples were identified by the edgeR software. Gene Ontology (GO) and pathway enrichment analysis of DEGs were performed, followed by metabolic pathway network construction. Moreover, pathways with higher connectivity degrees in the metabolic pathway network were identified.; Results Totally, 877 up- and 520 downregulated DEGs were screened. The upregulated DEGs such as IL-4 (Interleukin-4) were significantly related with immune system process, transmembrane signaling receptor activity, and signal transducer activity. Downregulated DEGs (i.e., Smad9 (SMAD family member 9), BMPR2 (bone morphogenetic protein type 2 receptor), and Eng (endoglin)) were significantly enriched in signal transducer activity, growth factor binding, and signal transduction. The top 10 metabolic pathways with highest connectivity degree were screened, including leishmaniasis (degree = 26), antigen processing and presentation (degree = 20), hematopoietic cell lineage (degree = 20), chemokine signaling pathway (degree = 18), and JAK-STAT signaling pathway (degree = 18).; Conclusions Smad9, BMPR2, Eng and IL4, and their relative functions such as signal transduction, signal transducer activity, and immune system process might play important roles in schistosomiasis-induced PAH. Moreover, the interaction of metabolic pathways was critical in the development of schistosomiasis-PAH.
