BPA and Chlorine Means Bad News: Modified Forms of Bisphenol A Found to Alter Hormone Signaling in New, Disturbing Ways

The ubiquity of the endocrine-disrupting chemical bisphenol A led researchers to ask what it might be doing in publicly supplied, chlorinated drinking water. The answer: Chlorinated BPA has different, but no less profound effects on cell-signaling networks than unmodified BPA. (Credit: © Artusius / Fotolia) July 17, 2013 — The ubiquity of the endocrine-disrupting chemical…

Combinations of estrogen-mimicking chemicals found to strongly distort hormone action

Contact: Jim Kelly jpkelly@utmb.edu 409-772-8791 University of Texas Medical Branch at Galveston For years, scientists have been concerned about chemicals in the environment that mimic the estrogens found in the body. In study after study, researchers have found links between these “xenoestrogens” and such problems as decreased sperm viability, ovarian dysfunction, neurodevelopmental deficits and obesity.…

Prenatal exposure to endocrine-disrupting chemicals linked to breast cancer

2010 study for filing Contact: Aaron Lohr alohr@endo-society.org 240-482-1380 The Endocrine Society A study in mice reveals that prenatal exposure to endocrine-disrupting chemicals, like bisphenol-A (BPA) and diethylstilbestrol (DES), may program a fetus for life. Therefore, adult women who were exposed prenatally to BPA or DES could be at increased risk of breast cancer, according…
