Estradiol rapidly (within 30 minutes) influences a variety of sociosexual behaviors in both mammalian and nonmammalian vertebrates, including goldfish, in which it rapidly stimulates approach responses to the visual cues of females. Such rapid neuromodulatory effects are likely mediated via membrane-associated estrogen receptors; however, the localization and distribution of such receptors within the nervous system is not well described. To begin to address this gap, we identified GPER/GPR30, a G-protein-coupled estrogen receptor, in goldfish (Carassius auratus) neural tissue and used reverse-transcription polymerase chain reaction (RT-PCR) and in situ hybridization to test if GPR30 is expressed in the brain regions that …
