Figure 8. Identification of two clusters using unsupervised consensus clustering. (A) Principal component analysis of two clustered distributions. (B) Differences in gene expression levels of HK2, PLOD2, and TREM1 between the two clusters. (C) Heatmap plot of the DEGs between the two clusters. (D) GO and KEGG enrichment analysis of the DEGs. DEGs, differentially expressed genes. GO, gene ontology. KEGG, Kyoto Encyclopedia of Genes and Genomes.
