Abstract WNT family member 4 (WNT4), which belongs to the conserved WNT protein family,
plays an important role in the development and differentiation of many cell types during the …

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

Sequential hermaphroditism is a unique reproductive strategy among teleosts that is
displayed mainly in fish species living in the coral reef environment. The reproductive …

Background Teleost fishes exhibit remarkably diverse and plastic sexual developmental
patterns. One of the most astonishing is the rapid socially controlled female-to-male …

Sex differentiation is a unique developmental process. Starting from a bipotential gonad, it
gives rise to the ovary and the testis, two highly specialized organs that differ …

Zebrafish males undergo a “juvenile ovary-to-testis” gonadal transformation process.
Several genes, including nuclear receptor subfamily 5, group A (nr5a) and anti-Müllerian …

To help understand the elusive mechanisms of zebrafish sex determination, we studied the
genetic machinery regulating production and breakdown of retinoic acid (RA) during the …

The wingless-type MMTV integration site family member-4 (Wnt4), a member of the wingless-
related integration site (Wnt) family, is widely accepted as a key regulator of ovarian …

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

Rock bream (Oplegnathus fasciatus) is a valuable commercial marine teleost species, which
exhibits sexual dimorphism in growth performance. However, the absence of a rapid and …
