1 RESULTS: We measured higher proliferation in ER+ breast cancer cells treated with BPA or its replacement, BPS, accompanied by an ERalpha-dependent decrease in genomic DNA hydroxymethylation. bisphenol A estrogen receptor 1 Homo sapiens
2 On the other hand, we observed that TET2 was negatively regulated by the activation of ERalpha (dimerized and phosphorylated), which was also induced by BPA/BPS binding. bisphenol A estrogen receptor 1 Homo sapiens
3 CONCLUSIONS: We identified a new feedback circuit of ERalpha activation-DNMT-TET2-DNA hydroxymethylation in ER+ breast cancer cells and uncovered a pivotal role of TET2-mediated DNA hydroxymethylation in modulating BPA/BPS-stimulated proliferation. bisphenol A estrogen receptor 1 Homo sapiens
