Xenoestrogens are a type of xenohormone that imitates estrogen.They can be either synthetic or natural chemical compounds.Synthetic xenoestrogens include some widely used industrial compounds, such as PCBs, BPA, and phthalates, which have estrogenic effects on a living organism even though they differ chemically from the estrogenic substances produced internally by the endocrine system of any ...
Xenoestrogens are xenohormones that mimic the effects of natural estrogen. When present in the body, xenoestrogens can bind with estrogen receptors in the brain, leading to a disruption in the gonadal endocrine system. Xenoestrogen exposure during different developmental periods can have differing effects on the reproductive system.
It has been hypothesized that plants use a phytoestrogen as part of their natural defense against the overpopulation of herbivore animals by controlling female fertility. [3] [4] The similarities, at molecular level, of an estrogen and a phytoestrogen allow them to mildly mimic and sometimes act as an antagonist of estrogen. [2]
Because they can mimic estrogen thus activating the receptor, they are considered harmful and potentially linked with breast cancer. [1] List of metalloestrogens include aluminium , antimony , arsenite , barium , cadmium , [ 2 ] chromium (Cr(II)), cobalt , copper , lead , mercury , nickel , selenite , tin and vanadate .
A comparison of the structures of the natural estrogen hormone estradiol (left) and one of the nonyl-phenols (right), a xenoestrogen endocrine disruptor. Endocrine disruptors, sometimes also referred to as hormonally active agents, [1] endocrine disrupting chemicals, [2] or endocrine disrupting compounds [3] are chemicals that can interfere with endocrine (or hormonal) systems.

That includes a current or past hormone receptor-positive cancer (primarily breast and endometrial cancers), as well as a history of stroke, blood clots or cardiovascular disease, Barbieri explains.
University of Texas researchers are working on 'e-skin' technology similar to human skin. The latest model has stretchy material, touch sensors. New 'e-skin' mimics human skin and could one day be ...
The mechanism of action of SERDs involves binding to the estrogen receptor, leading to a conformational change that facilitates recruitment of cellular machinery to degrade the receptor protein. By promoting degradation of the estrogen receptor, SERDs effectively inhibit estrogen signaling within cancer cells, thereby suppressing tumor growth.
