Expression of each nuclear factor-κB (NF-κB) subunit. (a) Sheets of large atypical lymphoid cells, which is a typical appearance of diffuse large B-cell lymphoma (DLBCL) (hematoxylin and eosin (H&E) × 600). Nuclear with or without cytoplasmic expression of each NF-κB subunit was considered positive (× 600). (b) Distribution of cell-of-origin with respect to expression of each NF-κB subunit. Two-sided P-value was calculated with Fisher’s exact test. ABC, activated B-cell-like; GCB, germinal center B-cell-like.
