RELA and aneurysmal bone cyst: 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).
