Use of Reporter Genes to Analyze Estrogen Response: The Transgenic Zebrafish Model

Methods Mol Biol. 2016;1366:315-325. doi: 10.1007/978-1-4939-3127-9_24.

Abstract

In vivo models to detect estrogenic compounds are very valuable for screening for endocrine disruptors. Here we describe the use of transgenic estrogen reporter zebrafish as an in vivo model for identification of estrogenic properties of compounds. Live imaging of these transgenic fish provides knowledge of estrogen receptor specificity of different ligands as well as dynamics of estrogen signaling. Coupled to image analysis, the model can provide quantitative dose-response information on estrogenic activity of chemical compounds.

Keywords: Estrogen; Fluorescence microscopy; Image analysis; Transgenic zebrafish; Xenoestrogens.
