Identification of Female-Specific,Serum Proteins (Vitellogenin) and Their Related Egg Yolk Proteins in Red Sea Bream, Pagrus major

, 1987
Female-specific serum proteins (vitellogenin) and their derivatives in egg yolk proteins of red sea bream, Pagrus major, were studied immunologically, electrophoretically and chromatographically.

An immunochromatographic test strip for in situ identification of Vitellogenin induction in fish exposed to Xenoestrogens

, 2007
An immunochromatographic test strip based on gold colloid was developed to quickly identify vitellogenin(VTG) induction in fish in field waters. The results indicated that the immunochromatographic test strip could perform the analysis with 100 mu L ...

Vitellogenin Induction as a Biomarker for Environmental Estrogens in Xenopus laevis

, 2004
In oviparous vertebrates, estrogen stimulates the liver to produce vitellogenin. Vitellogenin induction is a useful biomarker for exposure to endocrine disruptors, specifically environmental estrogens.

Relationship between reproductive success and male plasma vitellogenin concentrations in cunner, Tautogolabrus adspersus

, 2003
The gene for vitellogenin, an egg yolk protein precursor, is usually silent in male fish but can be induced by estrogen exposure. For this reason, vitellogenin production in male fish has become a widely used indicator of exposure to exogenous estrogens ...

Immunohistochemical detection of vitellogenin in male brown trout from Swiss rivers

, 1998
The detection of vitellogenin , a yolk precursor protein, may serve as a biomarker for exposure to environmental oestrogens as its induction by xenobiotic oestrogens in the immature and male fish has been reported repeatedly.

A vitellogenin antibody in honey bees (Apis mellifera ): Characterization and application as potential biomarker for insecticide exposure

, 2019
The insect yolk precursor vitellogenin is a lipoglycoprotein synthesized and stored in the fat body and secreted into the hemolymph. In honey bees, vitellogenin displays crucial functions in hormone signaling, behavioral transition of nurse bees to ...

Rice Stripe Virus Infection Facilitates the Reproductive Potential of Laodelphax striatellus

Agronomy
The rice stripe virus (RSV) is transmitted by the small brown planthopper Laodelphax striatellus in a persistent and circulative–propagative manner. During the last few decades, RSV has caused serious disease outbreaks in rice fields in China.

Plasma vitellogenin in free-ranging loggerhead sea turtles (caretta caretta) of the northwest atlantic ocean

, 2014
Vitellogenin is the egg yolk precursor protein produced by oviparous vertebrates. As endogenous estrogen increases during early reproductive activity, hepatic production of vitellogenin is induced and is assumed to be complete in female sea turtles ...
