Steroid hormones are involved in the regulation of a variety of processes like embryonic
development, sex differentiation, metabolism, immune responses, circadian rhythms, stress …

Unlike that of mammals, the brain of teleost fish exhibits an intense aromatase activity due to
the strong expression of one of two aromatase genes (aromatase A or cyp19a1a and …

Neuroactive steroids synthesized in neuronal tissue, referred to as neurosteroids, are
implicated in proliferation, differentiation, activity and survival of nerve cells. Neurosteroids …

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

Neurosteroids are defined as steroids de novo synthesized in the central nervous system.
While the production of neurosteroids is well documented in mammals and amphibians …

The brain of adult teleost fish exhibits several unique and interesting features, notably an
intense neurogenic activity linked to persistence of radial glial cells acting as neural …

Protandrous black porgy fish, Acanthopagrus schlegeli, have a striking life cycle with a male
sex differentiation at the juvenile stage and male-to-female sex change at 3years of age. We …

Background Teleosts are characterized by a remarkable breadth of sexual mechanisms
including various forms of hermaphroditism. Sparidae is a fish family exhibiting gonochorism …

Because a large proportion of potential endocrine disruptors (EDC) end up in surface
waters, aquatic species are particularly vulnerable to their potential adverse effects. Recent …
