Aromatase is an enzyme that catalyzes the synthesis of estrogen in gonads and brain. Teleost fish express aromatase (AroB) strongly in the brain facilitating its detailed examination. To understand the function of AroB in the brain, we generated transgenic zebrafish that expresses green fluorescent protein (GFP) driven by the brain aromatase cyp19a1b promoter. GFP was found in the radial glial cells of transgenic larvae and adult fish that overlap with AroB immunoreactivity in the correct temporal and spatial pattern. GFP was also coexpressed with radial cell marker BLBP, but was not in neurons. In addition, GFP expression in the radial glial cells was stimulated by estrogen, same as endogenous AroB expression. Thus, this transgenic line faithfully mimics the regulation of AroB expression in radial glial cells. It provides a powerful tool to further characterize progenitor radial cells in adult and developing fish and to evaluate estrogenic activities of xenoestrogens and phytoestrogens.
