Genomic, proteomic, and metabolomic technologies continue to receive increasing interest from environmental toxicologists. This interest is due to the great potential of these technologies to identify detailed modes of action and to provide assistance in the evaluation of a contaminant?s risk to aq...
ORGANISM(S): Danio rerio 
Classical embryological studies revealed that during mid-embryogenesis vertebrates show similar morphologies. This “phylotypic stage” has recently received support from transcriptome analyses, which have also detected similar stages in nematodes and arthropods. A conserved stage in these three p...

The morphogen Sonic H edgehog governs a wide range of developmental processes. The zebrafish genetic mutant iguana has vascular stability defects due to decreased Shh signaling. Using iguana mutant embryos and embryos treated with the Hedgehog pathway inhibitor cyclopamine, we conducted a microarray...
