miRNA-PDGFRB/HIF1A-lncRNA CTEPHA1 Network Plays Important Roles in the Mechanism of Chronic Thromboembolic Pulmonary Hypertension. Int Heart J. 2019 Jun 14;: Authors: Wang M, Gu S, Liu Y, Yang Y, Yan J, Zhang X, An X, Gao J, Hu X, Su P Abstract Our previous studies have revealed that long noncoding RNAs (lncRNAs), microRNAs (miRNAs), and genes were abnormally expressed in the pulmonary artery tissues of the chronic thromboembolic pulmonary hypertension (CTEPH) patients. We aim to establish the CTEPH-related miRNA-gene-lncRNA network for finding the core genes and associated miRNA and lncRNA in CTEPH patients.Firstly, the target genes of differential miRNAs were predicted by searching TargetScan databases, and the predicted target genes were intersected with the mRNAs from the gene chip. Secondly, the intersective genes were analyzed by the Gene Ontology function and Kyoto Encyclopedia of Genes and Genomes pathway software for obtaining differential intersective genes and then establish the miRNA-gene networks. Thirdly, the possible genes regulated by the differential lncRNAs from the gene chip were intersected with the above-screened mRNA to build the lncRNA-mRNA networks. Subsequently, the miRNA-gene-lncRNA networks were constructed according to the two networks above (miRNA-gene networks and lncRNA-mRNA networks). Finally, the core genes of the networks in the experimental group were screened according to Diffk > 0.6 and used to...
