The GSEA results showed that the CD47 high expression group in MDS tissues was mainly enriched in Hallmark pathways, such as heme metabolism, G2M checkpoint, and E2F target (Figure 5A), and in KEGG pathways, such as pressin-regulated water reabsorption, cell cycle, and spliceosome (Figure 5B). Here, CD47 is linked to myelodysplastic syndrome.
