Evaluating the Endocrine‐Disrupting and Oxidative Stress Potential of a 50‐Component Human‐Relevant Complex Chemical Mixture Using In Vitro Tests

Journal of Applied Toxicology, Volume 46, Issue 6, Page 2003-2018, June 2026.
ABSTRACT Humans are chronically exposed to mixtures of environmental contaminants. Exposure to endocrine‐disrupting chemicals (EDCs) contributes to increased health impairment observed globally. This study aimed to evaluate the endocrine‐disruptive and oxidative stress potential of a human‐relevant, complex chemical mixture in vitro.

Update of the risk assessment on dioxins and dioxin‐like PCBs in feed and food

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract The European Commission asked EFSA to update its 2018 risk assessment on polychlorinated dibenzo‐p‐dioxins and dibenzofurans (PCDD/Fs) and dioxin‐like polychlorinated biphenyls (DL‐PCBs) in feed and food, based on the 2022 WHO Toxic Equivalency Factors (WHO2022‐TEFs).

Impact of organic pollutants on phenotype and gene expression in human breast cancer cells

Journal of Applied Toxicology, Volume 46, Issue 5, Page 1487-1505, May 2026.
ABSTRACT Human exposure to industrial chemical compounds is widespread and, although often beneficial, prolonged contact may contribute to disease development, including cancer. While many studies have shown organic pollutants (OP) are cytotoxic, few have explored how long‐term exposure alters cell phenotype.

Investigation of Potential Risks in Bio‐Based Food Contact Materials (FCMs) From Microbial Exploitation of Agricultural Wastes: Case Studies of Bacterial Cellulose and Nisin

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT In the context of the circular economy and the increasing demand for safe and sustainable packaging, this work addresses the safety assessment of food contact materials (FCMs) derived from agro‐industrial by‐products. Despite growing interest in these bio‐based materials, the literature still lacks a structured safety‐assessment framework able

Prenatal exposure to TCDD and atopic conditions in the Seveso second generation: a prospective cohort study

Environmental Health, 2018
Background 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a toxic environmental contaminant that can bioaccumulate in humans, cross the placenta, and cause immunological effects in children, including altering their risk of developing allergies.

Melatonin Regulates Arylhydrocarbon Receptor Mediated UVR‐Induced Processes Related to Inflammation, Skin Aging and Carcinogenesis in Human Ex Vivo Skin

Experimental Dermatology, Volume 35, Issue 5, May 2026.
UVR causes formation of AhR and associated damaging molecules in human skin involved in inflammation, skin aging, and carcinogenesis and therefore impairing skin health. Melatonin pre‐incubation of human skin samples protects from UVR by reducing formation of AhR and associated downstream molecules. Thus, melatonin contributes to skin health.

Dexamethasone‐Mediated Regulation of CYP3A4 and UGTs in Human Hepatoma HuH‐7 Cells

Fundamental &Clinical Pharmacology, Volume 40, Issue 3, May 2026.
ABSTRACT Background The application of human hepatic cell lines to early drug discovery and development instead of human primary hepatocytes (HPHs) has been limited because of the low level of drug‐metabolizing enzymes (DMEs). Objective The study aimed to evaluate the effects of dexamethasone (DEX) treatment on DME expression, activities, and ...
