In an article published on March 7, 2014 by the news agent Headlines & Global News, Samantha Goodwin reports on a study finding that bisphenol A (BPA) promotes and may even cause breast cancer growth. The researchers from the University of Arlington, U.S. found high levels of BPA to provoke the body to produce high amounts of long, non-coding RNA (HOTAIR) in tumor cells as well as in normal breast tissue. HOTAIR suppresses genes that would normally slow tumor growth. The association was found at high exposure levels of BPA in combination with endogenous estrogen. In a press release published March 6, 2014, Bhan, lead author of the study states that increased presence of HOTAIR also in normal breast tissue begs the question whether in addition to tumor growth, HOTAIR and BPA may also be involved in tumor genesis.
