Compared with less metastatic cells (MCF-7), metastatic breast cancer cells (MDA-MB-231) have relatively open chromatin structure on the CRE, which facilitates direct binding of NFATc2 and NFKB1/RELA to enhance Ets1 expression and invasiveness of metastatic breast cancers, accordingly. Here, NFATC2 is linked to breast carcinoma.
