Abstract
Aberrant constitutive expression of c-Rel, p65 and p50 NF-κB subunits has been reported in over 90% of breast cancers1,2. Recently, we characterized a de novo RelB NF-κB subunit synthesis pathway, induced by the cytomegalovirus (CMV) IE1 protein, in which binding of p50–p65 NF-κB and c-Jun–Fra-2 AP-1 complexes to the RELB promoter work in synergy to potently activate transcription3. Although RelB complexes were observed in mouse mammary tumours induced by either ectopic c-Rel expression4 or carcinogen exposure5, little is known about RelB in human breast disease. Here, we demonstrate constitutive de novo RelB synthesis is selectively active in invasive oestrogen receptor alpha (ERα)-negative breast cancer cells. ERα signalling reduced levels of functional NF-κB and Fra-2 AP-1 and inhibited de novo RelB synthesis, leading to an inverse correlation between RELB and ERα gene expression in human breast cancer tissues and cell lines. Induction of Bcl-2 by RelB promoted the more invasive phenotype of ERα-negative cancer cells. Thus, inhibition of de novo RelB synthesis represents a new mechanism whereby ERα controls epithelial to mesenchymal transition (EMT).
