To better understand the mass poisonings from pharmaceuticals to which diethylene glycol was mistakenly added, toxicologists examined how the metabolite diglycolic acid accumulates in kidney cells and specifically what role, if any, sodium dicarboxylate transporters play. The results of that study are a ToxSpotlight article, “Role of Plasma Membrane Dicarboxylate Transporters in the Uptake and Toxicity of Diglycolic Acid, a Metabolite of Diethylene Glycol, in Human Proximal Tubule Cells,” in the November 2022 issue of Toxicological Sciences (ToxSci).

The other November 2022 ToxSpotlight article, “St. John’s Wort Exacerbates Acetaminophen-Induced Liver Injury by Activation of PXR and CYP-Mediated Bioactivation,” investigates how St. John’s wort interacts with high levels of acetaminophen to determine whether St. John’s wort may temper or exacerbate the severe hepatotoxicity caused be excessive use of acetaminophen.

Both ToxSpotlight articles are free to read for nonsubscribers and appear alongside six other research papers:

• “Exposure to the Organophosphate Pesticide Fenitrothion Directly Induced Defects in Mouse Embryonic External Genitalia” (topic category: developmental and reproductive toxicology)
• “Gestational Benzo[a]pyrene Exposure Destroys F1 Ovarian Germ Cells Through Mitochondrial Apoptosis Pathway and Diminishes Surviving Oocyte Quality” (topic category: developmental and reproductive toxicology)
• “Caveolin-1 and Its Functional Peptide CSP7 Affect Silica-Induced Pulmonary Fibrosis by Regulating Fibroblast Glutaminolysis” (topic category: environmental toxicology)
• “LncRNA HOTAIRM1 Involved in Nano NiO-Induced Pulmonary Fibrosis via Regulating PRKCB DNA Methylation-Mediated JNK/c-Jun Pathway” (topic category: nanotoxicology)
• “Arsenic Induces GSK3β-Dependent p-Tau, Neuronal Apoptosis, and Cognitive Impairment via an Interdependent Hippocampal ERα and IL-1/IL-1R1 Mechanism in Female Rats” (topic category: neurotoxicology)
• “Validation of Risk-Stratification Method for the Chronic Atrioventricular Block Cynomolgus Monkey Model and Its Mechanistic Interpretation Using 6 Drugs With Pharmacologically Distinct Profile” (topic category: regulatory science, risk assessment, and decision-making)
