A pregnancy early in reproductive life is protective against breast cancer, but the molecular mechanisms that form the basis for this protective effect have not been elucidated. In the October 16 early online edition of Proceedings of the National Academy of Sciences, Lakshmi Sivaraman and colleagues from Baylor College of Medicine, Houston, Texas, showed that the tumor suppressor protein p53 is increased in early pregnancy in rats and mice, possibly explaining why early pregnancy is associated
