Regulation of vitellogenesis in Drosophila
International Journal of Insect Morphology and Embryology, 1993Abstract During vitellogenesis the 3 major yolk proteins of Drosophila are synthesized and transported from the tissues which produce them to the oocyte. Here they are endocytosed by the oocyte and stored in yolk granules for utilization during embryogenesis.

A specific radioimmunoassay for vitellogenesis in mosquitoes
Journal of Insect Physiology, 1977Abstract Hagedorn's assay for vitellogenesis, in which a crude antigen-antibody complex is collected directly on a Millipore membrane, without prior separation of soluble from insoluble proteins, is unspecific. This was proven as follows. Fat bodies of blood-fed mosquitoes ( Aedes aegypti ) were incubated in a medium containing 3 H valine.

Malaria, dengue and other mosquito-borne infections are among the most devastating diseases (57, 144). The maintenance and dispersal of mosquito-borne disease depends upon the successful reproduction of the mosquito. The cornerstone of the reproductive cycle is vitellogenesis involving massive production of yolk protein precursors and their ...

Oogenesis in Fundulus heteroclitus. III. Vitellogenesis
Journal of Experimental Zoology, 1983AbstractSeveral physiological parameters associated with oocyte growth (vitellogenesis) in the killifish, Fundulus heteroclitus, are defined. Hepatocytes from females and estrogen‐treated males are highly synthetic cells, whereas those from males are relatively quiescent.

Endocrinology of Vitellogenesis
1987The ovum (female germ cell) is truly the most remarkable of all animal cells: once activated, it can give rise to a complete new individual and it is the only cell, in higher animals, that is capable of doing so. The most distinguished feature of the ovum is its large size, which is required for the storage of reserves for the development of the embryo.

5 Vitellogenesis and Oocyte Assembly
1988Publisher Summary This chapter describes the different aspects of vitellogenesis and oocyte assembly. The major components of fish oocytes are derived from the blood-borne high-molecular-weight compound, vitellogenin, which is synthesized in the liver of oviparous vertebrates.

Oocyte Growth and Vitellogenesis
1988In the last few years, due to the advances made in biochemistry, electron microscopy, and cytochemistry, a functional approach to the solution of a number of problems regarding the biology of development has become possible. One of these problems is the development of the organization of the mature egg.

Hormonal and Genetic Regulation of Vitellogenesis in Drosophila
The Quarterly Review of Biology, 1982Morphological, genetic, and hormonal studies of the process of vitellogenesis, whereby yolk is accumulated in the developing oocytes, have been going on for many years in Drosophila. Recently there has been a resurgence of interest in vitellogenesis, for it provides a model system for investigating how eukaryotic genes are regulated. The proteins found
