RelA driven co-expression of CXCL13 and CXCR5 is governed by a multifaceted transcriptional program regulating breast cancer progression.

Biochim Biophys Acta Mol Basis Dis 2018 Dec 12. Epub 2018 Dec 12.

Immunology Laboratory, Department of Zoology, University of Calcutta, Kolkata 700019, India. Electronic address:

Lethal metastasis of primary breast tumors to lymph nodes has been found to be associated with the co-expression of chemokine CXCL13 and its receptor CXCR5. To date, however, the precise molecular events regulating the co-expression of CXCL13 and CXCR5 in the context of breast cancer progression have not been identified. Therefore, to extend our understanding of the drivers of breast cancer metastasis, we undertook a line of investigation in this study in which we demonstrate that the transcriptional regulation of CXCL13 is mediated by the reciprocal activity of RelA and Nrf2, while CXCR5 is transcriptionally silenced by CpG island methylation within its promoter.
