Identification of key pathways and hub genes in the myogenic process of pluripotent stem cell: A bioinformatics study

Abstract

Purpose: The study aims to determine the process of myoginc differentiation in human pluripotent stem cells and to figure out that the key pathways and hub genes in the process, which do helpful for the further research of muscular regeneration.Method: Three gene expression profiles, GSE131125, GSE148994, GSE149055, about the comparisons of pluripotent stem cells and myogenic stem cells from the Gene Expression Omnibus (GEO) data base. Common differentially expressed genes (DEGs) were obtained and for the further analysis as Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) and GSEA analysis and protein‑protein interaction (PPI) network. In vitro cell research to verify the hub genes and key pathways.Result:824 DEGs were co-expressed in the three GSEs. 19 hub genes were identified from the PPI network. The GO and KEGG pathway analysis were performed to determine the functions of DEGs. GSEA analysis indicated the differentiated cells were enriched in muscle cell development and myogenesis.Conclusion: Our research revealed the main hub genes and modules in the myogeinc process of stem cells which contribute to further study about the molecular mechanism of myogenesis regeneration. Paving a way for more accurate treatment for muscle dysfunction.
