A gene ontology (GO) analysis revealed that genes positively correlated with DDR1 expression in DLBCL were enriched for GO terms including ‘collagen catabolic process’, ‘collagen metabolic process’ and ‘wound healing’ as well as ‘regulation of apoptosis’ and ‘cell migration’, reflecting known DDR1 functions (Figure S3A). Here, DDR1 is linked to diffuse large B-cell lymphoma.
