Journal of Biological Chemistry, 1982 Avian vitellogenin consists of two major species designated VTG I and VTG II. Rooster hepatocytes were employed to identify intracellular forms of the vitellogenins and to characterize biosynthetic intermediates of VTG I and VTG II. After labeling with [3H]serine, intracellular vitellogenin radioactivity was seen in mature VTG I and VTG II but was ...

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

Effects of the Herbicide Atrazine on Crustacean Reproduction. Mini-Review
Frontiers in Physiology, 2022 Atrazine, one of the most intensively applied herbicides worldwide, is commonly found in several water bodies, affecting the associated fauna. Autochthon crustacean species have been relatively less studied, compared to vertebrate species, particularly ...

Insect tissue-specific vitellogenin facilitates transmission of plant virus
PLoS Pathogens, 2018 Insect vitellogenin (Vg) has been considered to be synthesized in the fat body. Here, we found that abundant Vg protein is synthesized in Laodelphax striatellus hemocytes as well. We also determined that only the hemocyte-produced Vg binds to Rice stripe

Proteomic analysis of fertilized egg yolk proteins during embryonic development
Poultry Science, 2020 Egg yolk is an important source of nutrients for embryo development. In this study, the egg yolk protein composition at 0, 10, and 18 D of incubation was analyzed by 2-dimensional gel electrophoresis (2-DE) combined with matrix-assisted laser desorption ...

Expression and Role of Vitellogenin Genes in Ovarian Development of Zeugodacus cucurbitae
Insects, 2022 Vitellogenin (Vg) genes encode the major egg yolk protein precursor in arthropods. In this study, four Vgs were identified in Zeugodacus cucurbitae (Coquillett). Sequence analysis showed that four ZcVgs had the conserved Vg domain.

Scientific Reports, 2019 Vitellogenin is the main yolk precursor protein in insect oocytes. It is synthesized in the fat body and released into the hemolymph. To reach the oocyte surface, vitellogenin must cross a single layer of follicular epithelium cells.

Vitellogenin—Homologs of mammalian apolipoproteins?
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1991 1. To determine if a relationship exists between vertebrate vitellogenins and mammalian plasma proteins the EMBL and NBRF computer databases were searched with two partial amino acid sequences from Xenopus laevis and Gallus gallus vitellogenin. 2.
