Expression analysis of vitellogenins in the workers of the red imported fire ant (Solenopsis invicta) [PDF]

open access: yesPeerJ, 2018
Vitellogenin has been proposed to regulate division of labor and social organization in social insects. The red imported fire ant (Solenopsis invicta) harbors four distinct, adjacent vitellogenin genes (Vg1, Vg2, Vg3, and Vg4).

Vitellogenins - Yolk Gene Function and Regulation in Caenorhabditis elegans

open access: yesFrontiers in Physiology, 2019
Vitellogenins are a family of yolk proteins that are by far the most abundant among oviparous animals. In the model nematode Caenorhabditis elegans, the 6 vitellogenins are among the most highly expressed genes in the adult hermaphrodite intestine, which

In ovo omnia: diversification by duplication in fish and other vertebrates : [minireview] [PDF]

open access: yes, 2009
Gene and genome duplications are considered to be the main evolutionary mechanisms contributing to the unrivalled biodiversity of bony fish. New studies of vitellogenin yolk proteins, including a report in BMC Evolutionary Biology, reveal that the genes ...

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 and embryo proteogenomic dataset revealing diversity of vitellogenins in the crustacean Gammarus fossarum

open access: yesData in Brief, 2016
Ovaries and embryos from sexually mature Gammarus fossarum were sampled at different stages of the reproductive cycle. The soluble proteome was extracted for five biological replicates and samples were subjected to trypsin digestion.

Caste-specific expressions and diverse roles of takeout genes in the termite Reticulitermes speratus

open access: yesScientific Reports, 2023
Acquisition of novel functions caused by gene duplication may be important for termite social evolution. To clarify this possibility, additional evidence is needed. An important example is takeout, encoding juvenile hormone binding protein. We identified
