bisphenol A induces growth, differentiation, and c-fos gene expression in the female reproductive tract.
Disruption of Parity-Induced Tumor Suppressor Pathways by Xenoestrogen
Low levels of BPA, however, act additively with xenoestrogen
and natural estrogens (Silva, Rajapakse, & Kortenkamp, 2002; Soto, Chung, & Sonnenschein, 1994; Soto, Fernandez, Luizzi, Oles Karasko, & Sonnenschein, 1997; Tollefesen, 2002).
Increased oviposition with increasing sources of xenoestrogen
source is a logical trend given the estrogenic effects of these compounds in living organisms.
BPA is a xenoestrogen
, a man-made compound that has estrogenic effects.
One example is bisphenol-A, a major component in plastic containers, which was shown to be a xenoestrogen
, a breast cancer-causing agent.
4) More specifically, BPA is a xenoestrogen
, which mimics the relative bioactivity of estrogen.
Cancers specific to female reproductive organs such as the breast, uterus and ovary, are associated with higher long-term exposure to oestrogen, and numerous studies have shown that environmental xenoestrogen
presence and exposure is higher in urban areas.
This study was designed to quantify xenoestrogen
presence in a US wastewater effluent.
The principal metabolite derived from DDT is called DDE, a xenoestrogen
that lingers in fat deposits in the human body for decades.
peril is not yet front-page news, but it would come as no surprise to Rachel Carson, the early environmentalist who in 1962 first pointed an accusing finger at DDT.
SS: A xenoestrogen
is like the molecule of estrogen we have floating around in our body--normally it attaches to an estrogen receptor site.
