Gene set enrichment analysis (GSEA) of individual hub genes. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed via GSEA for six signature genes (LCN2, CBS, TLR8, NQO1, ABCB1, and TWIST1). GO, Gene ontology; KEGG, Kyoto encyclopedia of genes and genomes; GSEA, Gene set enrichment analysis.
