Exposure to copper nanoparticles causes gill injury and acute lethality in zebrafish (Danio rerio).
Increasing use of metallic nanomaterials is likely to result in release of these particles into aqueous environments; however, it is unclear if these materials present a hazard to aquatic organisms.Expand

Comparison of molecular and histological changes in zebrafish gills exposed to metallic nanoparticles.
Research has demonstrated that metallic nanoparticles produce toxicity in aquatic organisms that is due largely to effects of particulates as opposed to release of dissolved ions. The presentExpand

Vitellogenin induction and reduced serum testosterone concentrations in feral male carp (Cyprinus carpio) captured near a major metropolitan sewage treatment plant.
Endocrine disrupting chemicals can potentially alter the reproductive physiology of fishes. To test this hypothesis, serum was collected from common carp (Cyprinus carpio) at five riverine locationsExpand

Vitellogenin as a Biomarker of Exposure for Estrogen or Estrogen Mimics
Vitellogenin, the egg yolk precursor protein, has become a popular biomarker for measuring exposure of oviparous animals to estrogen or estrogen mimics. Vitellogenin is normally produced by femalesExpand

Differential expression of largemouth bass (Micropterus salmoides) estrogen receptor isotypes alpha, beta, and gamma by estradiol
The expression levels of three estrogen receptor (ER) isotypes alpha, beta, and gamma were quantified in female largemouth bass (Micropterus salmoides) (LMB) liver, ovary, brain, and pituitaryExpand

Fathead minnow (Pimephales promelas) vitellogenin: purification, characterization and quantitative immunoassay for the detection of estrogenic compounds.
The egg yolk precursor protein, vitellogenin (VTG), was purified from blood plasma of 17beta-estradiol (E2)-treated male fathead minnows (Pimephales promnelas) by anion-exchange chromatography onExpand

Universal assay of vitellogenin as a biomarker for environmental estrogens.
Vitellogenin (VTG), the serum phospholipoglycoprotein precursor to egg yolk, is potentially an ideal biomarker for environmental estrogens. This study was undertaken to develop antibodies againstExpand

Vitellogenin mRNA regulation and plasma clearance in male sheepshead minnows, (Cyprinodon variegatus) after cessation of exposure to 17 beta-estradiol and p-nonylphenol.
Research was conducted to determine the kinetics of hepatic vitellogenin (VTG) mRNA regulation and plasma VTG accumulation and clearance in male sheepshead minnows (Cyprinodon variegatus) during andExpand

Altered Serum Sex Steroids and Vitellogenin Induction in Walleye (Stizostedion vitreum) Collected Near a Metropolitan Sewage Treatment Plant
Several recent in situ studies have reported that domestic and mixed domestic/industrial sewage effluents contain one or more natural or anthropogenic estrogenic substances. Those studies examinedExpand
