Figure 4. Differentially expressed genes (DEGs) screening and pathway enrichment analysis between the two clusters. (A) The volcano plot of all DEGs between two clusters. (B, C) GSEA analysis reveals GO terms (B) and KEGG terms (C) enriched by DEGs between the two clusters. (D) Enriched GO terms and KEGG pathways of DEGs. (E) Expression of the markers of ferroptosis in the two clusters. (F) Correlation of LAMP2 and MDM4 with the markers of ferroptosis.
