Vitellogenesis and Embryogenesis in Spiders: A Biochemical Perspective [PDF]

open access: yesInsects
This review compiles information on the biochemistry of spider reproduction, from vitellogenesis to postembryonic development. Despite the diversity of spiders, biochemical studies on their reproduction remain scarce.

Blood-feeding adaptations and virome assessment of the poultry red mite Dermanyssus gallinae guided by RNA-seq [PDF]

open access: yesCommunications Biology, 2023
Dermanyssus gallinae is a blood-feeding mite that parasitises wild birds and farmed poultry. Its remarkably swift processing of blood, together with the capacity to blood-feed during most developmental stages, makes this mite a highly debilitating pest ...

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

open access: yesZoological 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 ...

Research Note: Comprehensive proteomic, phosphoproteomic, and N-glycoproteomic analysis of chicken egg yolk plasma [PDF]

open access: yesPoultry Science
: Chicken egg yolk plasma (EYP), the supernatant fraction of egg yolk obtained by water dilution and centrifugation, is a rich source of various bioactive substances and a significant bearer of yolk-emulsifying properties.

Egg Protein Compositions over Embryonic Development in Haemaphysalis hystricis Ticks [PDF]

open access: yesAnimals
Tick eggs contain a series of proteins that play important roles in egg development. A thorough characterization of egg protein expression throughout development is essential for understanding tick embryogenesis and for screening candidate molecules to ...

Molecular evolution of bumble bee vitellogenin and vitellogenin‐like genes [PDF]

open access: yesEcology and Evolution, 2021
AbstractVitellogenin (Vg), a storage protein, has been significantly studied for its egg yolk precursor role in oviparous animals. Recent studies found that vitellogenin and its Vg‐like homologs were fundamentally involved in many other biological processes in social insects such as female caste differences and oxidative stress resilience.

Endomitosis controls tissue-specific gene expression during development.

open access: yesPLoS Biology, 2022
Polyploid cells contain more than 2 copies of the genome and are found in many plant and animal tissues. Different types of polyploidy exist, in which the genome is confined to either 1 nucleus (mononucleation) or 2 or more nuclei (multinucleation ...

Autofluorescence as a noninvasive biomarker of senescence and advanced glycation end products in Caenorhabditis elegans

open access: yesnpj Aging and Mechanisms of Disease, 2021
To assess the utility of autofluorescence as a noninvasive biomarker of senescence in Caenorhabditis elegans, we measured the autofluorescence of individual nematodes using spectrofluorometry. The fluorescence of each worm increased with age.

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

open access: yesIntegrated 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
