Vitellogenesis in insects and other groups: a review [PDF]
Memorias do Instituto Oswaldo Cruz, 1993 The eggs from oviparous organisms contain large amounts of vitellus, or yolk, wich are utilized by the growing embryo. Vitellogenesis is the process of vitellus accumulation and involves massive heterosynthetic synthesis of the protein vitellogenin (Vg ...

Journal of Basic and Applied Zoology, 2013 Vitellogenesis in Orientocreadium batrachoides, an intestinal parasite of the catfish, Clarias gariepinus was investigated by transmission electron microscope. Four stages of vitellocyte development have been distinguished during vitellogenesis: (I) stem

BMC Genomics, 2009 Background In oviparous vertebrates, including fish, vitellogenesis consists of highly regulated pathways involving 17β-estradiol (E2). Previous studies focused on a relatively small number of hepatic expressed genes during vitellogenesis.

Multihormonal Control of Vitellogenesis in Lower Vertebrates
, 2004 The comparative approach on how and when vitellogenesis occurs in the diverse reproductive strategies displayed by aquatic and terrestrial lower vertebrates is presented in this chapter; moreover, attention has been paid to the multihormonal control of hepatic vitellogenin synthesis as it is related to seasonal changes and to vitellogenin use by ...

Nutritional Effects on Vitellogenesis in Species of Drosophila
Journal of Entomological Science, 2000 A comparative study of vitellogenesis in response to feeding was made in females of three species of the genus Drosophila, belonging to different species groups. The process of vitellogenesis, although conservative, shows significant differences in species phylogenetically distant to D. melanogaster (Meigen). Females of D.

The F-box protein FBXL-5 governs vitellogenesis and lipid homeostasis in C. elegans
Frontiers in Cell and Developmental BiologyThe molecular mechanisms that govern the metabolic commitment to reproduction, which often occurs at the expense of somatic reserves, remain poorly understood.

The cell biology of mosquito vitellogenesis
Memórias do Instituto Oswaldo Cruz, 1987 Insect vitellogenesis involves coordinated activities of the fat body and oocytes. We have studied these activities at the cellular level in the mosquito. During each vitellogenic cycle, the fat body undergoes three successive stages: 1) proliferation of biosynthetic organelles, 2) vitellogenin synthesis, 3) termination of vitellogenin synthesis and ...

Unravelling the changes during induced vitellogenesis in female European eel through RNA-Seq: What happens to the liver? [PDF]
PLoS ONE, 2020 The life cycle of European eel (Anguilla anguilla), a catadromous species, is complex and enigmatic. In nature, during the silvering process prior to their long spawning migration, reproductive development is arrested, and they cease feeding.

Frontiers in Cellular and Infection Microbiology, 2020 Ticks are blood-sucking vector arthropods, which play an important role in transmitting pathogens between humans and animals. RH36 is an immunomodulatory protein expressed in the salivary glands, but not other organs, of partially fed Rhipicephalus ...
