Unusual Functions of Insect Vitellogenins: Minireview
Physiological Research, 2023 Insect vitellogenins are an intriguing class of complex proteins. They primarily serve as a source of energy for the developing embryo in insect eggs. Vitellogenesis is a complex hormonally and neurally controlled process that command synthesis of vitellogenin molecules and ensures their transport from the female fat bodies or ovarial cells into eggs ...

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 ...

Food Safety and Health, EarlyView.This study shows the protective effects of potential probiotic strain of Pediococci strains against diarrheal Escherichia coli strains in Caenorhabditis elegans model system. The E. coli strains resulted in severe morphological and physiological damage to the worm whereas the probiotic interventions were able to reduce these damages.

Egg yolk hydrolysate shows moderate impact on osteoporosis in ovariectomized rats
Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND This study investigated the protective effect of egg yolk hydrolysate (FC) on osteoporosis in ovariectomized (OVX) rats, a well‐established model of postmenopausal bone loss. OVX rats were fed diets supplemented with 0.2% or 1% FC for 13 weeks.

A crustacean vitellogenin-derived peptide as an oocyte-specific delivery vehicle for gene silencing
Frontiers in Marine Science, 2023 Gene silencing by dsRNA is well documented in crustaceans, but RNA interference (RNAi) in developing oocytes is yet to be achieved. The main obstacle to RNAi in the oocytes of oviparous animals derives from their protective layers, including the ...

Regulatory mechanisms of reproduction in locusts and grasshoppers
New Plant Protection, EarlyView.Regulatory networks composed of numerous coding and noncoding genes play crucial roles in the reproduction of locusts and grasshoppers. This review integrates mechanistic advances in reproductive regulation, highlighting environmentally adaptive pathways and providing prospective targets for eco‐friendly pesticides.
