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 ...

Cytokines in mammalian reproduction and speculation about their possible involvement in nonmammalian viviparity

, 1997
In recent years, the secretion of immunoregulatory factors (cytokines) at the maternofetal interface in mammals has been widely documented. Although cytokine production seems to be a specific phenomenon in mammalian reproduction, the specific roles of ...

Multiscale Effects of Environmentally Relevant Mixtures Containing Two Estrogenic Endocrine Disruptors, Chlordecone and Propylparaben, in Hydra vulgaris Pallas, 1766

Environmental Toxicology, EarlyView.
ABSTRACT This study investigates the chronic effects of chlordecone (CLD) and propylparaben (PP), two pro‐estrogenic endocrine disruptors, on Hydra vulgaris Pallas, 1766 using a multiscale approach over a 14‐day exposure period. Environmentally relevant concentrations of CLD (0.5, 5, 20 μg L−1) and PP (0.01, 0.05, 0.40 μg L−1) were tested individually ...

Competition for the in vitro binding of radioiodinated human follicle-stimulating hormone in reptilian, avian, and mammalian gonads by nonmammalian gonadotropins [PDF]

, 1976
Radioiodinated human FSH (125I-hFSH) was used to study the specificity of the gonadotropin binding sites of various reptilian, avian, and mammalian gonadal tissues by examining competitive interactions with several nonmammalian gonadotropins.

Understanding extracellular vesicles in antiaging

Periodontology 2000, EarlyView.
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

KU80 suppresses endonuclease G activity to preserve genomic integrity

The FEBS Journal, Volume 293, Issue 19, Page 5952-5966, October 2026.
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.

Inhibition of nonmammalian glycosidases by azetidine iminosugars derived from stable 3,5-di-O-triflates of pentoses.

, 2011
Efficient ring closure of stable crystalline 3,5-di-O-triflates of pentofuranosides with amines to form azetidines allowed preliminary evaluation of four-ring iminosugars as glycosidase inhibitors; significant and specific inhibition of nonmammalian α ...

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 ...
