Exposure to copper nanoparticles causes gill injury and acute lethality in zebrafish (Danio rerio).
TLDR
Zebrafish were exposed to 100 microg/L of nanocopper or to the concentration of soluble copper matching that present due to dissolution of the particles, clearly demonstrating that the effects of Nanocopper on gill are not mediated solely by dissolution.
Comparison of molecular and histological changes in zebrafish gills exposed to metallic nanoparticles.
TLDR
Global gene expression analysis demonstrates that the exposure to each nanometal or soluble metal produces a distinct gene expression profile at both 24 and 48 h, suggesting that each exposure is producing biological response by a different mechanism.
Vitellogenin induction and reduced serum testosterone concentrations in feral male carp (Cyprinus carpio) captured near a major metropolitan sewage treatment plant.
TLDR
The data suggest that North American rivers are receiving estrogenic chemicals that are biologically active, as has been reported in Great Britain.
Vitellogenin as a Biomarker of Exposure for Estrogen or Estrogen Mimics
TLDR
Methods for purifying vitellogenin from plasma, generating antibodies, and performing assays to measure viteLLogenin are discussed.
Toxicogenomics in regulatory ecotoxicology.
TLDR
Roles of toxicogenomics in the field of regulatory ecotoxicology are considered, current limitations in the science and practice of genomics are explored, and possible avenues to approach and resolve some of the major challenges are proposed.
Universal assay of vitellogenin as a biomarker for environmental estrogens.
TLDR
The results indicate that it is feasible to generate antibodies capable of recognizing VTG without regard to species and that development of a universal VTG assay is an achievable goal.
Altered Serum Sex Steroids and Vitellogenin Induction in Walleye (Stizostedion vitreum) Collected Near a Metropolitan Sewage Treatment Plant
TLDR
The results demonstrate that the St. Paul metropolitan STP continues to release an estrogenic effluent, capable of inducing VTG production and altering normal serum sex steroid concentrations in a commercially valuable, native fish, the walleye.
