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.

In ovo omnia: diversification by duplication in fish and other vertebrates : [minireview] [PDF]
, 2009 Gene and genome duplications are considered to be the main evolutionary mechanisms contributing to the unrivalled biodiversity of bony fish. New studies of vitellogenin yolk proteins, including a report in BMC Evolutionary Biology, reveal that the genes ...

Effects of Flight on Gene Expression and Aging in the Honey Bee Brain and Flight Muscle [PDF]
, 2012 Honey bees move through a series of in-hive tasks (e.g., “nursing”) to outside tasks (e.g., “foraging”) that are coincident with physiological changes and higher levels of metabolic activity.

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.
