Disruption of thyroid hormone signaling is a form of endocrine disruption that is of concern to both human health and ecosystems. Research is being conducted to define the biological targets chemicals may interact with to disrupt thyroid hormone signaling and the stages in development where that disruption can most readily lead to adverse effects. The present data characterize the expression of key genes associated with thyroid hormone signaling and regulation over the course of development for two small fish widely used in aquatic ecotoxicology research. These data provide baseline information that can lead to a more complete understanding of which thyroid disrupting chemicals fish may be susceptible to and at which stages in development.
