Vitellogenin and vitellogenin receptor gene expression and 20-hydroxyecdysone concentration in Macrobrachium rosenbergii exposed to chlordecone.
Chlordecone is a persistent organochlorine pesticide widely used in Guadeloupe (French West Indies) to control the banana weevil Cosmopolites sordidus. Although it was previously highlighted that chlordecone may affect the reproduction and growth of vertebrate species, little information is available on the chlordecone effects in invertebrates. The present study investigated the effects of chlo...
متن کاملStudy of Vitellogenin Motif
Vitellogenin (VTG) is known to be a female-specific protein and a precursor form of egg yolk. Threevitellogenin,Vtg I,Vtg II and Vtg III have been identified in chicken.Vitellinogen precursors supply the major egg yolk proteins which are a source of nutrients during early development of egg-laying (oviparous) vertebrates and invertebrates. A complete structural analysis and 3-D modelling of Vit...
متن کاملSocial exploitation of vitellogenin.
Vitellogenin is a female-specific glucolipoprotein yolk precursor produced by all oviparous animals. Vitellogenin expression is under hormonal control, and the protein is generally synthesized directly before yolk deposition. In the honeybee (Apis mellifera), vitellogenin is not only synthesized by the reproductive queen, but also by the functionally sterile workers. In summer, the worker popul...
متن کاملAnalysis of vitellogenin gene structure in Caspian roach, Rutilus caspicus (Pisces: Cyprinidae) during exposure to Atrazine
Chemical contamination of aquatic environments to EDCs has become a major focus of environmental toxicology research. The exposure of fishes to estrogenic EDCs in aquatic environments is most frequently assessed by analyzing Vitellogenin (Vg) (the egg yolk precursor protein) expression. Therefore, characterization of Vg gene is of high priority for EDCs bio-monitoring. So, we prepared liver tis...
متن کاملSequestered and Injected Vitellogenin
Vitellogenin (1, 2) is a sex-limited phosphoprotein secreted by the liver in Xenopus females (3, 4) and selectively transferred via the circulatory system to growing oocytes, within which it is converted into the yolk proteins lipovitellin and phosvitin (3, 5, 6) . Selective uptake (7) and conversion (8) of vitellogenin can also take place in isolated oocytes . The available evidence indicates ...
