Immunoblotting Reactivity of Vitellogenin Antibodies against Native Vitellogenins and a Vitellogenin Protein Fragment Produced in E. coli

Journal of Applied Biological Chemistry, 2009
Vitellogenin (Vtg) is found in the serum of both female and male fish that have been exposed to environmental endocrine disrupters or estrogen hormones, and is used as a biomarker for such contamination. In our current study antibodies raised against the purified flatfish Vtg were tested for their reactivity on immunoblots to flatfish and carp Vtg, and

Predicted exposures to steroid estrogens in U.K. rivers correlate with widespread sexual distruption in wild fish populations

, 2005
Steroidal estrogens, originating principally from human excretion, are likely to play a major role in causing widespread endocrine disruption in wild populations of the roach (Rutilus rutilus) , a common cyprinid fish, in rivers contaminated by treated ...

Vitellogenin synthesis in the avian liver. Vitellogenin is the precursor of the egg yolk phosphoproteins

Journal of Biological Chemistry, 1975
Administration of estrogen to roosters induces the synthesis of egg yolk phosphoproteins in the liver. We have demonstrated that these proteins are synthesized in the form of a large precursor, vitellogenin, and that vitellogenin is the only phosphoprotein found in the plasma of the estrogen-treated rooster. Vitellogenin is cleaved to form the egg yolk

Ovarian Development and Vitellogenin Gene Expression under Heat Stress in Silkworm, Bombyx mori

Psyche: A Journal of Entomology, 2016
The present study observed the effect of heat stress on ovarian development, fecundity, and vitellogenin gene expression in silkworm, Bombyx mori. The result showed that the heat shock treatment to spinning larvae and pupae at 39°C (1 h and 2 h) did not ...
