Network module‐based drug repositioning for pulmonary arterial hypertension

Abstract: Pulmonary arterial hypertension (PAH) is a progressive disorder characterized by pulmonary vascular remodeling leading to increased pulmonary vascular resistance and pulmonary arterial pressure. PAH is a highly morbid cardiopulmonary disease adversely affecting lifespan and quality of life. Despite increased awareness and advances of medical therapies in recent decades, long-term prognosis and survival remain poor for patients with PAH. Novel therapies that can target the underlying pathobiology of PAH and rev… Show more

“…Furthermore, due to availability of biological biospecimens from our study population, we were not able to perform experimental validation (qRT-PCR and Western Blot) on CD4 + T cells but only in PBMC fraction. Larger prospective studies are needed to evaluate whether network-oriented DMGs may be used as potential biomarkers to optimize prognosis in PAH [1,3,[50][51][52]. Nonetheless, circulating DNA methylome analyzed via network analysis may yield insight into early disease pathogenesis and suggest noninvasive biomarkers that can be used to optimize patient phenotyping and, possibly, predicted outcome in PAH.…”

“…Constructing the networks. The consolidated human protein-protein interactome were assembled from different resources as described before which contains 16,470 proteins and 233,957 interactions (19,23,24). We mapped the differentially expressed rat genes to human orthologs using the HGNC Comparison of Ortholog Predictions search tool, HCOP (https://www.genenames.org/tools/hcop/) and obtained 2,626 human genes.…”

“…Genes associated with amino acids were from the Gene Ontology (GO) database (http://geneontology.org/). Genes associated with PAH were compiled from different resources (19,23,24) and mapped to the human interactome to form a PAH disease module. Genes associated with pathophenotypes were compiled from Phenopedia and DisGeNET (52,53).…”

“…We used the comprehensive human protein–protein interactome consolidated in our previous study. 15 This human interactome contains physical, macromolecular interaction data from different human sources, including protein–protein interactions, protein complexes, kinase‐substrate interactions, and signaling pathways. High‐quality protein–protein interactions are identified from several high‐throughput yeast‐two‐hybrid studies, mass spectrometry, as well as the literature.…”
