Sequestered 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 ...
متن کاملVitellogenin 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 کاملVitellogenin Gene Expression and Sex Steroid Levels as Biomarkers in Yellowfin Seabream (Acanthopagrus latus) Exposed to Bisphenol-A
Background: The egg yolk precursor protein vitellogenin (VTG) has proven to be a useful biomarker, used to identify organisms exposed to estrogenic compounds. Methods: We investigated variations in the VTG gene expression pattern and plasma sex steroid hormones concentrations in the yellowfin Seabream, Acanthopagrus latus, (A. latus) by various doses of bisphenol-A (BPA) exposure for 7 and 14 ...
متن کاملDetermination of plasma vitellogenin levels and localization of vitellogenin in liver of Lake Van pearl mullet (Chalcalburnus tarichi Pallas, 1811)
This study focused on hepatosomatic and gonadosomatic index and levels of plasma 17β-estradiol (E2), vitellogenin (Vtg) and total protein and determined the localization of Vtg in the liver during vitellogenesis in female Chalcalburnus tarichi, an endemic cyprinid species living in the Lake Van, Turkey. The levels of plasma E2, Vtg and total protein in female fish increased during vitellogenesi...
متن کاملAlteration of pectoral fin nerves following ablation of fin buds and by ectopic fin buds in the Japanese medaka fish.
The role of the pectoral fin bud for outgrowth by fin axons was assessed by ablation of pectoral fin buds and by transplantation of fin buds to ectopic sites in the embryos of the Japanese medaka fish (Oryzias latipes). Normally nerves from segments 1-4 (S1-4) and less frequently the S5 nerve converged at the base of the fin bud by extending toward the fin bud on the ventral surface of the axia...
