Cell type specific polyploidization in the royal fat body of termite queens

Zoological Letters, 2023
Tissue-specific endopolyploidy is widespread among plants and animals and its role in organ development and function has long been investigated. In insects, the fat body cells of sexually mature females produce substantial amounts of egg yolk precursor ...

Vitellogenin synthesis in the avian liver. Vitellogenin is the precursor of the egg yolk phosphoproteins

Journal of Biological Chemistry, 1975
Administration of estrogen to roosters induces the synthesis of egg yolk phosphoproteins in the liver. We have demonstrated that these proteins are synthesized in the form of a large precursor, vitellogenin, and that vitellogenin is the only phosphoprotein found in the plasma of the estrogen-treated rooster. Vitellogenin is cleaved to form the egg yolk

The Essential Role of Vitellogenin Receptor in Ovary Development and Vitellogenin Uptake in Bactrocera dorsalis (Hendel) [PDF]

International Journal of Molecular Sciences, 2015
The vitellogenin receptor (VgR) functions as an essential component in uptaking and transporting vitellogenin (Vg) in female adults, which is involved in ovary development and oviposition. This study aimed to clarify the molecular characteristics and function of VgR in the oriental fruit fly Bactrocera dorsalis (Hendel).

Phoenixin-14 alters transcriptome and steroid profiles in female green-spotted puffer (Dichotomyctere nigroviridis)

Scientific Reports, 2022
Phoenixin (PNX) is a highly conserved, novel hormone with diverse functions, including hypothalamic control of reproduction, appetite modulation, and regulation of energy metabolism and inflammation.

Inconsistent Transcriptomic Responses to Hexabromocyclododecane in Japanese Quail: A Comparative Analysis of Results From Four Different Study Designs

Environmental Toxicology and Chemistry, EarlyView.
Abstract Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been ...

Vitellogenin—Homologs of mammalian apolipoproteins?

Comparative 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.

Comparative analysis of distinctive transcriptome profiles with biochemical evidence in bisphenol S- and benzo[a]pyrene-exposed liver tissues of the olive flounder Paralichthys olivaceus.

PLoS ONE, 2018
Flounder is a promising model species for environmental monitoring of coastal regions. To assess the usefulness of liver transcriptome profiling, juvenile olive flounder Paralichthys olivaceus were exposed to two pollutants, bisphenol S (BPS) and benzo[a]

Polyphenol dietary supplementation prevents inflammation‐induced muscle atrophy in a zebrafish (Danio rerio) model

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Diet‐induced inflammation is a major cause of muscle degeneration impacting human and animal health. Owing to their anti‐inflammatory and antioxidant properties, polyphenols have attracted considerable interest as feed additives.

Long‐term impact of exposure to Royal Guard, a pyriproxyfen‐based bed net, on pyrethroid‐resistant malaria vectors from Cameroon using DNA‐based metabolic resistance markers

Pest Management Science, Volume 81, Issue 4, Page 2165-2180, April 2025.
We used recently detected P450 DNA‐based markers of pyrethroid resistance in both Anopheles funestus and Anopheles gambiae to demonstrate that although pyrethroid‐resistant mosquitoes have higher ability to survive and live longer after exposure to Royal Guard, this net significantly affects their lifespan, blood feeding ability and interestingly ...
