Expression of steroid-related genes in electrosensory brain regions

This dataset contains the relative gene expression of four steroid-related genes in two electrosensory brain regions, the electrosensory lateral line lobe and the torus semicircularis, in two species of sexually dimorphic apteronotid electric knifefishes. Steroid-related genes of interest include androgen receptor α (ARα), androgen receptor β (ARβ), estrogen receptor α (ESRα), and aromatase (CYP19B). Gene expression was quantified with qPCR in both male and female <i>Apteronotus leptorhynchus</i> and <i>Apteronotus albifrons</i>. Dataset also includes information on body mass, reproductive condition (as measured by gonadosomatic index), electric organ discharge frequencies (EODf), 11-ketotestosterone levels, testosterone levels, and estradiol levels for each fish. Two replicates of this experiment were performed in 2022 and 2023. Animal care and experimental protocols were approved by the Indiana University Bloomington Institutional Animal Care and Use Committee.
