In human Estrogen Receptor alpha (ERalpha)-positive breast cancers, 5' end dense methylation of the estrogen-regulated pS2/TFF1 gene correlates with its transcriptional inhibition. However, in some ERalpha-rich biopsies, pS2 expression is observed despite the methylation of its TATA-box region. Herein, we investigated the methylation-dependent mechanism of pS2 regulation.
