Gene set enrichment analysis (GSEA) and DEG analysis identified upregulation of genes involved in proliferation (MKi67, CDK1, BUB1B, CDC20), metabolism (GYS2, STC1, KIF20), adhesion (ITGA8, ICAM1, VCAN), and ECMECM(MMP9, MMP10, COL4A4) pathways in DLBCL-FRCs (Figure 4B and Supplemental Figure 5C). Here, VCAN is linked to diffuse large B-cell lymphoma.
