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.

An Escherichia coli Phosphotransferase System Modulates Methylglyoxal Resistance by Regulating Intracellular Potassium

Molecular Microbiology, Volume 125, Issue 6, Page 461-474, June 2026.
Escherichia coli can survive methylglyoxal stress by modulating phosphorylation of a regulatory phosphotransferase system, which, in turn, regulates the activity of a potassium/proton antiporter. The constitutive potassium importer Trk also contributes to intracellular potassium levels.
