RNA activation in insects: From emerging evidence to molecular applications

Insect Molecular Biology, EarlyView.
Canonical RNA activation involves small RNAs interacting with promoter sequences, but there is also evidence of non‐canonical RNAa in eukaryotes. Emerging evidence suggests the presence of RNAa in insects. RNAa can be utilised as a tool for functional genomic studies in insects.

Chronic thermal stress affects growth, liver morphology and molecular responses but allows recovery at optimal temperature in juvenile zebrafish (Danio rerio)

Journal of Fish Biology, EarlyView.
Abstract Climate‐driven aquatic heatwaves pose an increasing threat to fish populations by inducing prolonged thermal stress. However, the resilience of teleosts to chronic heat exposure and their capacity for recovery remains poorly understood. This study investigated the effects of chronic high‐temperature exposure on juvenile zebrafish (Danio rerio).

Biosynthesis of mosquito vitellogenin.

Journal of Biological Chemistry, 1990
Vitellogenin (Vg), the hemolymph precursor to the major yolk protein in mosquitoes, is synthesized in the fat body of blood-fed females. Mosquito Vg consists of two subunits with Mr = 200,000 and 66,000. Here, we demonstrate that both the Vg subunits are first synthesized as a single precursor.

Dietary L‐Tyrosine Sustains Egg Production and Quality by Modulating Promoter CpG Methylation, Gene Expression, and Hormone Profiles in Reproductive Signalling Pathways of Aged Laying Hens

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Managing prolactin (PRL)‐mediated reproductive suppression is critical for maintaining egg production in commercial laying hens. L‐tyrosine (TYR), a precursor of dopamine (DA), may counteract age‐related reproductive decline by suppressing PRL, thereby sustaining productivity and egg quality in late‐phase laying hens.

Comparative analysis of immune responses in ovipositing and non‐ovipositing females of European earwig Analyse comparative de la réponse immunitaire avant et après la ponte chez le forficule européen

Physiological Entomology, EarlyView.
Oviposition and care decrease the total haemocyte concentration. Oviposition and care affect haemocyte type proportions. Serratia marcescens challenge does not affect the immune cell parameters. Abstract Reproduction and immunity are essential biological processes that compete for resources and energy.

Edible Insect Allergens: An Emerging Food Safety Challenge

Sustainable Food Proteins, Volume 4, Issue 3, September 2026.
Allergic responses to edible insects arise via two main pathways: cross‐reactivity with homologous arthropod allergens and primary sensitization to edible insect proteins, both leading to IgE‐mediated immune activation. ABSTRACT Edible insects are increasingly promoted as sustainable protein sources; however, their allergenic potential remains a ...

Oxidative stress in honey bees (Apis mellifera) and small carpenter bees (Ceratina calcarata) across different landscapes

Physiological Entomology, Volume 51, Issue 3, Page 526-536, September 2026.
First comparative study in oxidative stress between wild bees and managed bees. Bees collected from organic landscapes exhibited the lowest OX levels. Pesticide profiles were different among landscapes. Abstract Oxidative stress (OX) is a state of imbalance between antioxidants and reactive oxygen species, which are the byproducts of oxidative ...

A Quarter Century of EHD Protein Research: From Endosomal Recycling to Ciliopathies

Traffic, Volume 27, Issue 3, September 2026.
Human EHD protein subcellular localization. ABSTRACT Eps15 homology domain‐containing proteins comprise a conserved family of membrane‐remodeling ATPases that regulate endocytic trafficking, membrane fission, receptor recycling, primary ciliogenesis and membrane dynamics across eukaryotes. Since the initial identification of EHD1 and its Caenorhabditis

Histochemical characteristics of the vitellogenic oocytes of the bluefin tuna, Thunnus thynnus L.

Ciencias Marinas, 2002
 Very little information is available with respect to dynamic aspects of oocyte development and to yolk composition of tuna species. Since histological approaches can offer considerable information about the ovarian development of fish, and because ...
