Inhibition of kynurenine 3‐monooxygenase (KMO) reduces fentanyl and sucrose intake and relapse‐like behaviour in rats

British Journal of Pharmacology, Volume 183, Issue 18, Page 5458-5475, September 2026.
Abstract Background and Purpose Opioid use disorder, particularly involving fentanyl, poses major challenges due to high relapse rates and limited effectiveness of pharmacotherapies. The kynurenine pathway has emerged as a target for addiction treatment through its modulation of glutamatergic and dopaminergic neurotransmission.

Volatile Organic Compounds Emitted by Fungi Have Substantial Effects on Growth and Disease Resistance in Arabidopsis thaliana

Plant, Cell &Environment, Volume 49, Issue 9, Page 7168-7190, September 2026.
ABSTRACT Volatile organic compounds (VOCs) emitted by certain fungi have previously been suggested to modulate plant development and their response to stresses. While some fungal species, such as Trichoderma harzianum, are known to produce VOCs, the production of VOCs in other phylogenetically divergent species, such as Mucor mucedo, was previously ...

A Non‐Canonical Role of SMAD4 in Regulating 3D Genome Architecture to Inhibit Lung Squamous Cell Carcinoma Development

Advanced Science, Volume 13, Issue 47, 24 August 2026.
SMAD4 is identified as a guardian of 3D genome architecture in lung squamous cell carcinoma. Loss of SMAD4 unleashes EP300 at chromatin loop anchors, strengthening enhancer–promoter looping and H3K27ac at the SOX2 locus to drive aberrant SOX2 activation and tumor cell proliferation.

Titanium Detected in Liver, Kidney, Spleen, and Intestine Is Not Related to Dose, Time, or Route of Exposure to Titanium Dioxide: A Systematic Review

Environmental Toxicology, Volume 41, Issue 8, Page 537-548, August 2026.
ABSTRACT Titanium dioxide (TiO2), used as a food additive (labeled E171 in Europe), was withdrawn from the European market in 2022. The E171 toxicity mechanism involves its uptake, oxidative stress, DNA damage, and inflammation. It has been hypothesized that the TiO2 accumulation nanoparticles (NPs) or E171 triggers tissue damage, and some studies have

Ocratoxins and their nephrotoxic potential

Revista de Nefrología, Diálisis y Trasplante, 2019
Ochratoxins are fungal metabolites that are present in a wide variety of foods and their byproducts. Nephrotoxicity is its main toxic effect, related in turn to different clinical syndromes such as tubular necrosis or Balkan nephropathy.
