To establish whether similar variability is present in ABC- and GC-DLBCL we measured the levels of NF-κB in two ABC- (RIVA and U2932) and two GC-DLBCL (SUDHL8 and SUDHL10) cell lines (Fig. 2B), and identified varied expression of both RelA and RelB, which did not align with Cell Of Origin (COO) classification (Fig. 2B). The gene discussed is RELA; the disease is diffuse large B-cell lymphoma.
