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

open access: yesFrontiers 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. Phylogenetic analyses showed that NlVg-like1 and NlVg-like2 are not clustered with the conventional insect Vgs associated with vitellogenesis.

PRY-1/Axin signaling regulates lipid metabolism in Caenorhabditis elegans. [PDF]

open access: yesPLoS ONE, 2018
The nematode Caenorhabditis elegans constitutes a leading animal model to study how signaling pathway components function in conserved biological processes. Here, we describe the role of an Axin family member, PRY-1, in lipid metabolism.

Social exploitation of vitellogenin [PDF]

open access: yesProceedings 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 ...

Insect Bacterial Symbiont-Mediated Vitellogenin Uptake into Oocytes To Support Egg Development

open access: yesmBio, 2020
Many insect species, such as aphids, leafhoppers, planthoppers, and whiteflies harbor obligate bacterial symbionts that can be transovarially transmitted to offspring through the oocytes of female insects.

Proteomic evaluation of citrate-coated silver nanoparticles toxicity in Daphnia magna [PDF]

open access: yes, 2014
Recent decades have seen a strong increase in the promise and uses of nanotechnology. This is correlated with their growing release in the environment and there is concern that nanomaterials may endanger ecosystems. Silver nanoparticles (AgNPs) have some

Molecular Characterization of Neoseiulus barkeri Vitellogenin Genes and Vitellogenin Receptor during Reproductive Diapause [PDF]

open access: yesInsects, 2020
The relationship between reproductive diapause and the genes related to vitellogenin (Vg) and its receptor (VgR) in insectoid ovarian development is still unclear. Accordingly, in the present study, we used hematoxylin and eosin staining to study the ovarian structure in the predatory mite Neoseiulus barkeri, a species that shows promise as a ...

Roles of Estrogens in the Healthy and Diseased Oviparous Vertebrate Liver

open access: yesMetabolites, 2021
The liver is a vital organ that sustains multiple functions beneficial for the whole organism. It is sexually dimorphic, presenting sex-biased gene expression with implications for the phenotypic differences between males and females.

Ovary Development and Maturation in Nezara viridula (L.) (Hemiptera: Pentatomidae) [PDF]

open access: yes, 2011
Ovary development and maturation of Nezara viridula (L.) were evaluated by examining ovariole morphology and the alterations in the biochemical (protein synthesis related to reproduction) composition of the hemolymph. Quantitative and qualitative protein
