To test whether HCMV infection is associated with activation/phosphorylation of NF-κB/p65 (Ser276), we measured phospho-NF-kB p65 (Ser276) in HCMV infected and non-infected carcinoma tissues of non-IBC and IBC patients using immunoblot and immunohistochemistry. The gene discussed is NFKB1; the disease is cytomegalovirus infection.
