  • n. An egg-yolk precursor protein expressed in the females of nearly all oviparous species.

Etymologies

Sorry, no etymologies found.

Examples

  • The fat body cells respond to it by making a yolk ingredient called vitellogenin.

    Parasite Rex

  • The vitellogenin leaves the fat body and flows through the beetle until it reaches the eggs in the ovaries.

    Parasite Rex

  • It makes a molecule that gets into the fat body and slows down the cells as they make vitellogenin.

    Parasite Rex

  • With enough of these hormones, the vitellogenin can reach the egg itself and turn into yolk.

    Parasite Rex

  • Some vitellogenin still gets out of the fat body, but little of it seems to reach an egg.

    Parasite Rex

  • Mosquito vitellogenin (Vtg) genes belong to a small multiple gene family that encodes the major yolk protein precursors required for egg production.

  • Previous studies identified vitellogenin, a gene that also is active in fat cells.

  • This ligand is efficient in the induction of the vitellogenin gene, one of the biomarkers that frequently has been used to detect estrogenic effects in male fish

    PLoS ONE Alerts: New Articles

  • The multiplicity or loss of the vitellogenin (vtg) gene family in vertebrates has been argued to have broad implications for the mode of reproduction (placental or non-placental), cleavage pattern (meroblastic or holoblastic) and character of the egg (pelagic or benthic).
