In fish as in other vertebrates, the diverse functions of thyroid hormones are mediated at the peripheral tissue level through iodothyronine deiodinase (dio) enzymes and thyroid hormone receptor (tr) proteins. In this study, we examined thyroid hormone regulation of mRNAs encoding the three deiodinases dio1, dio2 and dio3 - as well as three thyroid hormone(More)
Environmental variation holds a central role in determining the distribution and diversity of species. For any given taxon, the number and type of environmental variables that govern its distribution can range widely, but commonly include both abiotic parameters (e.g. temperature, salinity, wave energy, substratum shelter) and biotic variables such as food(More)
Several estuaries along the Pacific Ocean coast of North America were identified recently as having elevated 4-nonylphenol (4-NP) in sediments and biota, raising concerns about reproductive impacts for wildlife given 4-NP's established estrogenic activity as an endocrine-disrupting compound. Here we characterize 4-NP mediated induction and recovery of(More)
