Xenoestrogen
Xenoestrogens are clinically significant because they can mimic the effects of endogenous estrogen and thus have been implicated in precocious puberty and other disorders of the reproductive system.
E-SCREEN
The biological effects of estrogens (and xenoestrogens) are mediated through the estrogen receptor (ER). Estrogen receptors, which belong to a large superfamily of nuclear receptors, are transcription factors that induce transcription of target genes after binding to specific DNA sequences in their promoter.
