Development of a Zebrafish Embryo‐Based Test System for Thyroid Hormone System Disruption: 3Rs in Ecotoxicological Research

Environmental Toxicology and Chemistry, EarlyView.
Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.

EE2 and the Fish Brain: Age‐Dependent Impact of 17α‐Ethinylestradiol on Brain Cell Proliferation and Behavior in Sea Bass Larvae

Environmental Toxicology, EarlyView.
ABSTRACT Endocrine‐disrupting chemicals (EDCs), such as 17α‐ethinylestradiol (EE2), have raised concerns about their potential effects on aquatic organisms, particularly during early developmental stages. In this context, the study of behavioral disruption has gained considerable attention, as it may have consequences on individual fitness and ...

KU80 suppresses endonuclease G activity to preserve genomic integrity

The FEBS Journal, EarlyView.
Under normal conditions, EndoG remains restricted to mitochondria and the genome remains intact. When KU80 is absent, EndoG translocates into the nucleus, where it promotes DNA fragmentation and genomic instability. Thus, this work highlights the importance of KU80 in tightly controlling EndoG localization to preserve genome stability.

Alternative Developmental Toxicity Screening Methods Using Chick Embryo‐Based Models

Journal of Applied Toxicology, Volume 46, Issue 8, Page 2640-2649, August 2026.
ABSTRACT Nonclinical developmental toxicity studies are used to investigate the potential toxicities of drugs and chemical candidates on normal embryonic and fetal development during pregnancy, generally using mammalian laboratory animals such as rats and rabbits.

Enteric Nervous System Damage by Food Contaminants: A Pathway to Neurodegeneration?

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT The enteric nervous system (ENS), a key component of the gut–brain axis, has emerged as a critical player in the pathogenesis of Parkinson's disease (PD). It is the first neural system exposed to food contaminants (FCs)—a diverse group of ubiquitous toxic compounds fortuitously present in food derived from production, processing, storage, or ...

The Impacts of Pregnancy on Cognition and Cell Proliferation in a Live‐Bearing Fish (Poeciliopsis gracilis)

European Journal of Neuroscience, Volume 63, Issue 9, May 2026.
We assessed the impact of pregnancy on cognition and cell proliferation in the live‐bearing fish Poeciliopsis gracilis. Pregnant females showed reduced spatial learning but unchanged reversal learning, alongside decreased cell proliferation in the olfactory bulb and ventral telencephalon, indicating pregnancy‐induced cognitive and neural changes in a ...

Histone Density and Dynamics Shape Mitotic Chromatid Architecture in Xenopus Egg Extracts

Genes to Cells, Volume 31, Issue 3, May 2026.
Histone chaperones and chromatin remodelers modulate histone density and dynamics. The resulting local chromatin properties are integrated with DNA reconfiguration activities mediated by condensins and topoisomerase IIα to shape the global architecture of mitotic chromosomes.

When Pathways Converge: Iron, Lipid Peroxidation, and α‐Synuclein in Ferroptosis‐Driven Dopaminergic Neurodegeneration

Journal of Neurochemistry, Volume 170, Issue 4, April 2026.
Dopaminergic neurons are particularly susceptible to ferroptosis. Pacemaking activity–driven calcium (Ca2+) influx increases metabolic demand and reactive oxygen species (ROS) production, promoting iron release from aconitase. Alpha‐synuclein (α‐syn) enhances iron uptake via transferrin receptor 1 (TfR1) and exhibits ferrireductase activity, converting

Organ‐Specific Histopathological Effects of Prenatal Alcohol Exposure: A Narrative Review

Congenital Anomalies, Volume 66, Issue 1, January/December 2026.
ABSTRACT The role of alcohol‐induced epigenetic modifications that predispose the fetus to metabolic dysregulation, increased susceptibility to future substance use, and long‐term behavioral and cognitive impairments has received increasing attention.

Chelation Therapy for Rare Earth Element Toxicity: Current Evidence, Challenges and Future Directions

Basic &Clinical Pharmacology &Toxicology, Volume 138, Issue 1, January 2026.
ABSTRACT The accelerating integration of rare earth elements (REEs) in advanced technologies has generated rising concern over human exposure and the attendant toxicological risks. This review presents an up‐to‐date synthesis of current evidence on REE toxicity across multiple exposure pathways, including inhalation, ingestion and occupational contact,
