Seasonal shifts in mitochondrial and reactive oxygen species metabolism are linked to ultrastructural remodelling in honey bees (Apis mellifera)

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Seasonal changes profoundly reshape honey bee mitochondrial metabolism. In winter, bees shift from complex I (CI)‐ to mitochondrial glycerol‐3‐phosphate dehydrogenase (mG3PDH)‐ and complex II (CII)‐linked respiration. Despite lower CI‐linked respiration ATP production is maintained, suggesting increased energetic efficiency in ...

Oxidative Stress and DNA Epigenetic Modifications in Cancer: Mechanisms and Targeted Therapeutics

open access: yesMedComm – Oncology, Volume 5, Issue 2, June 2026.
Reactive oxygen species (ROS) modulate DNA methyltransferases (DNMTs), ten‐eleven translocation family proteins (TETs) and their cofactors, reshaping 5‐methylcytosine (5mC)/5‐hydroxymethylcytosine (5hmC)/5‐formylcytosine (5fC) landscapes and gene expression in cancer cells. In turn, epigenetic control of antioxidant and metabolic pathways feeds back on

Oxidative Stress in the Tumor Immune Microenvironment: Mechanisms and Therapeutic Perspectives

open access: yesMedComm – Oncology, Volume 5, Issue 2, June 2026.
Oxidative stress is involved in several key processes in cancer, including redox regulation, DNA damage, post‐translational modifications, transcriptional regulation, epigenetic modifications, metabolic reprogramming, cell death, and immune modulation. These mechanisms collectively influence tumor progression, immune evasion, and therapeutic responses,
