Among those metabolites, vitellogenin (Vtg) is synthesized in the digestive gland and is a precursor of vitellin
(Vn), a protein located in the yolk of maturing oocytes (Zimowska et al.
Reduced oviposition of Boophilus microplus feeding on sheep vaccinated with vitellin
Nous presentons, dans cet article, le cas clinique d'un patient atteint d'une tumeur du sac vitellin
du testicule au stade IIIc metastatique.
Vitellogenins and vitellins
in the bean bug, Riptortus clavatus (Hemiptera: Alydidae): purification, immunological identification, and induction by juvenile hormone.
This includes the expression of ovarian egg yolk protein, vitellin
4), supporting the hypothesis that the rabbit antibody was raised from yolk proteins, which are vitellin
or vitellinlike molecules (Suzuki et al.
Changes in vitellin
during oogenesis and effect of estradiol-17[beta] on vitellogenesis in the Pacific oyster Crassostrea gigas, Invertebr.
A slight increase in lipid and protein content in female gonad-visceral mass during sexual maturation was observed, demonstrating that lipid and protein would be accumulated as vitellin
The RNA:DNA ratio is a good indicator of sexual maturity in the gonad-visceral mass; the increasing RNA:DNA ratio in the gonad-visceral mass appears to show the rising synthetic activity of vitellin
within the gonad.
In vivo incorporation of labeled methionine into proteins, vitellogenin, and vitellin
in females of the shrimp Penaeus semisulcatus de Haan.
Oviparous invertebrates can synthesize the vitellin
within the ovary (Li et al.
These are taken up by vitellogenic oocytes via receptor-mediated endocytosis and become egg vitellins
