(a) BACH2 was detected in BACH2‐transfected FL‐18‐EB cells (FL‐18‐EB [BTB and CNC homology 2 (BACH2)+]) by PCR. (b) Phosphorylated transforming growth factor‐β‐activated kinase 1 (pTAK1) expression was downregulated in FL‐18‐EB (BACH2+) cells as shown by Western blot analysis. (c) p65 expression was downregulated in nuclear fractions of FL‐18‐EB (BACH2+) cells compared to FL‐18‐EB and FL‐18‐EB (control vector) cells. (d) The ratio of BACH2 expression level to LaminB1 is shown. (e) Immunohistochemistry in BACH2‐negative diffuse large B‐cell lymphoma (DLBCL) shows p65 positivity in the nucleus, pTAK1 positivity, and EBV‐encoded small RNA in situ hybridization (EBER (ISH)) positivity. (f) Immunohistochemistry in BACH2‐positive DLBCL shows p65 positivity in the cytoplasm, pTAK1 negativity, and EBER (ISH) negativity. (g) Immunohistochemistry in BACH2‐negative DLBCL shows nuclear staining of p50 and p52. (h) Immunohistochemistry in BACH2‐positive DLBCL shows cytoplasmic staining of p50 and p52.
