GO analysis of the 95 genes upregulated by DDR1 expression in GC B cells and differentially expressed in both GCB‐ and ABC‐DLBCL compared to normal GC B cells revealed the enrichment of genes with functions in ‘cell adhesion’, ‘leukocyte migration’, ‘angiogenesis’ and ‘positive regulation of cell proliferation’, reflecting known functions of DDR1 (Figure 5A). Here, DDR1 is linked to diffuse large B-cell lymphoma.
