AlterNet: "In an interview, study co-author Hugh S. Taylor, M.D., professor and chief of the reproductive endocrinology section at Yale University School of Medicine, said his team injected pregnant mice with BPA for just one week. After those mice, and a control group, gave birth, the scientists found that the genetic chemistry of female offspring exposed to BPA in the womb had been irrevocably altered.
A particular gene known as HOXA10, responsible for normal uterine development and fertility in both mice and humans, had been stripped of numerous so-called 'methyl groups,' each composed of a single hydrogen atom and three carbon atoms.
'We've discovered the exact mechanism by which BPA affects this gene,' Taylor said. 'This small group can have a powerful effect in turning genes on and off.'
