Estrogens have historically been associated with female reproduction, but work over the last
two decades established that estrogens and their main nuclear receptors (ESR1 and ESR2) …

Many natural and synthetic compounds present in the environment exert a number of
adverse effects on the exposed organisms, leading to endocrine disruption, for which they …

There are two estrogen receptor (ER) subtypes in fish, ERα and ERβ, and increasing
evidence that the ERβ subtype has more than one form. However, there is little information …

Three major phases compose spermatogenesis: mitotic proliferation of spermatogonia,
meiosis of spermatocytes, and spermiogenesis, the restructuring of spermatids into …

Sex steroid hormones are synthesized from cholesterol and exert pleiotropic effects notably
in the central nervous system. Pioneering studies from Baulieu and colleagues have …

Experiments were conducted to assess the in vivo potency of binary mixtures of estrogenic
chemicals using plasma vitellogenin (VTG) concentrations in juvenile rainbow trout …

The expression levels of three estrogen receptor (ER) isotypes alpha, beta, and gamma
were quantified in female largemouth bass (Micropterus salmoides)(LMB) liver, ovary, brain …

There are two estrogen receptor (ER) subtypes in fish, Esr1 and Esr2 (formerly ERα and
ERβ), and in some species the Esr2 subtype has two forms, Esr2b (formerly ERβ1) and …

Fish spermatogenesis, from spermatogonial stem-cell renewal to sperm maturation, is
controlled by the sex steroid hormones. Mitotic divisions of spermatogonia can be …

We have previously cloned and characterized three estrogen receptors (ER) in the zebrafish
(zfERalpha, zfERbeta1 and zfERbeta2). We have also shown that they are functional in vitro …
