| Outline of Final Research Achievements |
Teleost fish exhibit marked sex differences in a wide range of traits, including aggressive and reproductive behavior, growth, sexual maturation, and stress response. However, it remains to be elucidated what mechanisms in the teleost brain underlie these sex differences. In the present study, we have identified a novel teleost-specific gene that is expressed in the brain and presumably involved in stress response, and named it teleocortin. We have also provided the evidence that glucocorticoid receptor 1 expressed in the preoptic area most likely plays an important role in behavioral sex differences.
