The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome

Biological Reviews, Volume 101, Issue 4, Page 1877-1903, August 2026.
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Goniothalamin as a Styryl‐Lactone Toxicophore in Cancer Models: Electrophile‐Driven DNA Damage, Reactive Oxygen Species–Endoplasmic Reticulum Stress Signaling and Detoxification‐Relevant Safety Considerations

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 8, August 2026.
Goniothalamin (GTN) exerts anticancer effects by promoting reactive oxygen species (ROS) generation, glutathione (GSH) depletion, DNA damage, endoplasmic reticulum (ER) stress, and mitochondrial dysfunction. These interconnected events trigger apoptosis, necroptosis, anoikis, and autophagy, while modulating mitogen‐activated protein kinase (MAPK ...
