Estrogenic endocrine disrupting chemicals (EDCs) are natural hormones, synthetic
compounds or industrial chemicals that mimic estrogens due to their structural similarity with …

In all vertebrate species, estrogens play a crucial role in the development, growth, and
function of reproductive and nonreproductive tissues. A large number of natural or synthetic …

Rainbow darter (Etheostoma caeruleum) is a small benthic fish species found in North
America that are abundant and distributed throughout the Grand River watershed, ON …

Estrogen receptors (Er) play a critical role in vitellogenesis. Three ers (erα, erβ1 and erβ2)
and vitellogenins (vtg-A, vtg-B and vtg-C) subtypes were isolated in various fish species …

Abstract The US Environmental Protection Agency has responsibility for assessing
endocrine activity of more than 10 000 chemicals, a task that cannot reasonably be achieved …

For several years, environmental exogenous agents, called endocrine disruptors, are
suspected to interfere with the essential functions of reproduction and development in many …

Scope Phytoestrogens, such as the soy isoflavones genistein and daidzein, are suggested
to beneficially affect lipid metabolism in humans and thereby contribute to healthy ageing …

Estrogen receptors (ERs) play a critical role in vitellogenesis (Vtgs). However, the
contribution of each ER for the regulation of vtgs expression was not analyzed clearly in …

Fish are exposed to steroids of different classes in contaminated waters, but their effects are
not sufficiently understood. Here we employed an anti-sense technique using morpholino …

Background Vitellogenin (VTG) is a precursor of egg yolk proteins synthesized within the
liver of oviparous vertebrates. Betaine is an important methyl donor that is reported to …
