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 Estradiol-17β (E 2) promotes the transcription of vitellogenin (Vtg) via nuclear
estrogen receptor (ER). Three Vtg (VtgAa, VtgAb, and VtgC) and ER subtypes (ERα, ERβ1 …

Estrogens exert their biological functions through the estrogen receptors (ERs). In zebrafish,
three nuclear estrogen receptors (nERs) named ERα, ERβ1 and ERβ2 and one membrane …

During their breeding season, estrogen induces vitellogenin (VTG) production in the liver of
teleost fish through estrogen receptors (ERs) that support oocyte vitellogenesis. There are at …

Because European silver eels have never been caught during or after their 6000-km
reproductive migration to the Sargasso Sea, all existing knowledge on their sexual …

Estrogens regulate various reproductive processes via estrogen receptor (ER)-mediated
signaling pathway in vertebrates. In this study, full-length sequences coding for ERα, ERβ1 …

Vitellogenin (VTG) is a useful biomarker for detecting the estrogenic activity of chemicals in
aquatic environments. However, little information is available on the regulatory mechanisms …

Transcription of vitellogenin (vtg) genes are initiated when estradiol-17β (E 2)-estrogen
receptor (ER) complexes bind estrogen response elements (ERE) located in the gene …

Indigenous aquatic population such as fish could be used as a successful test species for
evaluating the ecological effects in aquatic environment. In the present study, vitellogenin …

Reproductively arrested gonadal development has been previously described in the teleost
pearl mullet (Chalcalburnus tarichi, Cyprinidae) from Van Edremit Gulf of Lake Van, Turkey …
