Proteomic characterization of vitellogenins from three species of South American fresh water fish

open access: yes, 2018
Vitellogenins (Vtg) are glycolipophosphoproteins synthesized by oviparous vertebrates as yolk proteins precursors. These proteins have been studied for their role in reproduction and in endocrine disruption.

Immunoblotting Reactivity of Vitellogenin Antibodies against Native Vitellogenins and a Vitellogenin Protein Fragment Produced in E. coli

open access: yesJournal of Applied Biological Chemistry, 2009
Vitellogenin (Vtg) is found in the serum of both female and male fish that have been exposed to environmental endocrine disrupters or estrogen hormones, and is used as a biomarker for such contamination. In our current study antibodies raised against the purified flatfish Vtg were tested for their reactivity on immunoblots to flatfish and carp Vtg, and

Sialotranscriptomics of the argasid tick Ornithodoros moubata along the trophogonic cycle.

open access: yesPLoS Neglected Tropical Diseases, 2021
The argasid tick Ornithodoros moubata is the main vector of human relapsing fever (HRF) and African swine fever (ASF) in Africa. Salivary proteins are part of the host-tick interface and play vital roles in the tick feeding process and the host infection

Transcriptome analysis in Ceratitis capitata to unveil genes involved in ageing-maturation process

open access: yesSpanish Journal of Agricultural Research, 2013
The sterile insect technique (SIT) is widely used in integrated programmes against the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae). Information on the age distribution of insects, and more particularly, the knowledge of

Co‐expression and regulation of ovarian vitellogenins in the Pacific oyster Crassostrea gigas

open access: yes, 2014
In addition to the reported single cDNA sequence encoding vitellogenin in the Pacific oyster Crassostrea gigas (referred as Cg-Vtg1), we isolated and characterized the 3′ end of a novel vitellogenin (Vtg) in C. gigas, named Cg-Vtg2.

Mugilid Fish Are Sentinels of Exposure to Endocrine Disrupting Compounds in Coastal and Estuarine Environments

open access: yesMarine Drugs, 2014
Effects on fish reproduction can result from a variety of toxicity mechanisms first operating at the molecular level. Notably, the presence in the environment of some compounds termed endocrine disrupting chemicals (EDCs) can cause adverse effects on ...

Four-way regulation of mosquito yolk protein precursor genes by juvenile hormone-, ecdysone-, nutrient-, and insulin-like peptide signaling pathways. [PDF]

open access: yes, 2014
Anautogenous mosquito females require a meal of vertebrate blood in order to initiate the production of yolk protein precursors by the fat body. Yolk protein precursor gene expression is tightly repressed in a state-of-arrest before blood meal-related ...

Vitellogenin—Homologs of mammalian apolipoproteins?

open access: yesComparative 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.

Reproduction is associated with a tissue-dependent reduction of oxidative stress in eusocial female Damaraland mole-rats (Fukomys damarensis). [PDF]

open access: yes, 2018
This is the final version of the article. Available from Public Library of Science via the DOI in this record.Oxidative stress has been implicated as both a physiological cost of reproduction and a driving force on an animal's lifespan.
