Vitellogenin and Vitellogenin-Like Genes in the Brown Planthopper [PDF]

Frontiers in Physiology, 2019
Vitellogenin (Vg) is precursor of vitellin. Here, we identified a Vg (NlVg) and two Vg-likes (NlVg-like1 and NlVg-like2) in the brown planthopper, Nilaparvata lugens.

Identification and Expression of vitellogenin gene in the Gouramy (Osphronemous Gourammy) under photoperiods manipulation

E3S Web of Conferences, 2018
Vitellogenin was protein hormone where controlled gonad development in fish. Expression of this gene regulated from the external and internal factor.Photoperiods are the external factor that regulated endocrine gland activities in gonadal development ...

Study of Vitellogenin Motif

, 2018
Shashank Rana ABSTRACT Vitellogenin (VTG) is known to be a female-specific protein and a precursor form of egg yolk. Threevitellogenin,Vtg I,Vtg II and Vtg III have been identified in chicken.Vitellinogen precursors supply the major egg yolk proteins which are a source of nutrients during early development of egg-laying (oviparous) vertebrates and ...

Relationships among tissues, biofluids, and otolith selenium concentrations in wild female burbot (Lota lota)

Integrated Environmental Assessment and Management, EarlyView., 2023
Abstract In the Lake Koocanusa‐Kootenai River system (Montana, USA and British Columbia, Canada), selenium (Se) contamination has become an international concern and is suspected to contribute to the observed burbot (Lota lota) population collapse. Due to our limited ability to sample burbot in Lake Koocanusa for monitoring studies, we used a reference

Social exploitation of vitellogenin [PDF]

Proceedings of the National Academy of Sciences, 2003
Vitellogenin is a female-specific glucolipoprotein yolk precursor produced by all oviparous animals. Vitellogenin expression is under hormonal control, and the protein is generally synthesized directly before yolk deposition. In the honeybee ( Apis mellifera ), vitellogenin is not only synthesized by the ...

Population Genetic Study of <i>vitellogenin</i> in Honey Bees (<i>Apis mellifera</i>) With European Ancestry Identifies Two Ancestral Genetic Backgrounds. [PDF]

Ecol Evol
Our work shows that honey bee vitellogenin (Vg) segregates into two main haplotype versions (haplogroups) defined by 65 common polymorphisms. One haplogroup is abundant in A. m. mellifera conservatory samples, and at the protein level, we identify protein‐coding differences concentrated in the lipid‐binding cavity. This provides a foundation for future

Induction of vitellogenin synthesis by estrogen in avian liver: relationship between level of vitellogenin mRNA and vitellogenin synthesis. [PDF]

Proceedings of the National Academy of Sciences, 1976
We have investigated the estrogen-mediated induction of vitellogenin synthesis in rooster liver. We compared the concentrations of vitellogenin messenger RNA (mRNA) in the liver with the concentrations of vitellogenin in the sera of roosters that had recieved various treatments with estrogen.

MOLECULAR CLONING OF THE VITELLOGENIN GENE IN THE HARD-LIPPED BARB (Osteochillus hasseltii C.V) AND PHOTOPERIOD'S EFFECTS ON GENE EXPRESSION

Biotropia: The Southeast Asian Journal of Tropical Biology, 2018
Photoperiod affects fish reproduction as it regulates activities of the endocrine glands, which produce the hormones needed for geonadal growth and development, gametogenesis, and reproductive cycles.

Expression of biomarkers connected to endocrine disruption in Cottus gobio and Salmo trutta fario in relation to sewage treatment plant-efflux and pesticides

Frontiers in Environmental Science, 2022
The increasing efflux on a large scale of organic contaminants holding endocrine disrupting activity from sewage treatment plants produces detrimental biological effects to various fish species.
