Do you ever have a tendency to breastfeed?
Mice that have been exposed to certain chemicals during their intrauterine development must be considered to have a higher risk of breast cancer in adults, according to a new animal experiment.Bisphenol A (BPA) and diethylstilbestrol (DES) are chemicals used primarily for industrial purposes. They are known to interfere with hormonal and metabolic processes, altering neurological and immunological functions in humans and humans.
"BPA is a weak-acting estrogen and DES a strong-potency, and our current research has shown that they both have a life-long effect on breast gene expression," said Dr. Hugh Taylor of New Haven School of Medicine.All substances with estrogenic effect, even weak estrogens, influence the development of the breast, and the effect on the fetus increases in the adolescent. The results will be published in the June issue of the Hormones & Cancer Journal of the Endocrinological Society.

Emlхrбkplayback The authors deduced their conclusions from the observation of pregnant mice exposed to BPA and DES. In these small mice, higher-than-normal EZH2 levels were observed in adulthood. This white plays an important role in gene regulation. Abnormally higher EZH2 levels pose higher risk for the memory - the scientists say.
"We have introduced a new mechanism by which endocrine-acting chemicals influence the subsequent mechanism of breast development," Taylor said. As a result of the research, new safety measures need to be taken with regard to endocrine agents in the environment, such as BPA.
