Gonadal steroidogenesis is pivotal to synchronize various reproductive stages including
sexual development, growth and maturation. In all vertebrates including teleost …

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 …

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 …

Endocrine disrupting chemicals (EDCs) have been a major concern in the normal
reproduction and development of aquatic organisms. In the teleost, steroid hormones are …

Organochlorine pesticides (OCPs) such as dieldrin are a persistent class of aquatic
pollutants that cause adverse neurological and reproductive effects in vertebrates. In this …

Eels are gonochoristic species whose gonadal differentiation initiates at the yellow eel stage
and is influenced by environmental factors. We revealed some sex-related genes were sex …

The early brain development, at the time of gonadal differentiation was investigated using a
protandrous teleost, black porgy. This natural model of monosex juvenile fish avoids the …

We investigated the developmental expression and localization of sf-1 and dax-1 transcripts
in the brain of the juvenile orange-spotted grouper in response to steroidogenic enzyme …
