“…For functional enrichment analysis, DEGs' functional enrichment analysis, including GO (Gene Ontology) and KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway enrichment, were performed using clusterProfiler (version 3.4.4) (Yu et al, 2012). For target gene enrichment analysis for different signaling pathways, in addition to the signaling pathways (TGF-b, Hedgehog, BMP, FGF, Nodal, and WNT) analyzed previously (Li et al, 2017a;Peng et al, 2016), two other signaling pathways (Notch and Hippo/Yap) were included in this analysis. Rank Prod (p < 0.001 for Notch and p < 0.01 for Hippo/Yap) results were generated using data from public datasets GSE15268 and GSE69669, respectively.…”
