RAD51 and RAD51 paralog inhibition sensitizes nonreplicating quiescent keratinocytes to UV radiation

open access: yesPhotochemistry and Photobiology, EarlyView.
UV radiation and other compounds generate DNA adducts that block transcription and induce cell death if not removed by the nucleotide excision repair system. In this work, we used a small‐scale pharmacological screen to discover that inhibition of the recombinase RAD51 sensitized nonreplicating quiescent keratinocytes to both UVR and other agents that ...

Intramuscular pathways of maladaptation in overtraining syndrome

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The transition from adaptive overreaching to maladaptive overtraining and mechanisms through which excessive training load can lead to performance decline. Four interconnected pathophysiological domains are highlighted: neural fatigue, involving both central and peripheral components such as altered sensory feedback and reflex ...

Drafting the calmodulation playbook: Emerging structural insights into transient receptor potential channel regulation by calmodulin

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Calmodulin (CaM) is a ubiquitous calcium (Ca2+) sensor that translates intracellular Ca2+ signals into modulation of hundreds of effector proteins including ion channels. CaM is increasingly recognized as a key regulator of the transient receptor potential (TRP) channel family, yet the underlying ‘calmodulation playbook’ is only ...

Lipoic acid functions in Paneth cells to prevent human intestinal stem cell aging

open access: yesNature Communications
Intestinal stem cell (ISC) aging diminishes the regenerative capacity of the intestinal epithelia, but effective therapeutic strategies to counteract human ISC aging remain elusive.

ID3 deficiency alters chromatin accessibility at DSB sites and enhances vulnerability to HDAC inhibition

open access: yesInternational Journal of Cancer, Volume 158, Issue 12, Page 3173-3186, 15 June 2026.
What's new? Errors in DNA double‐strand break (DSB) repair can lead to mutations, chromosomal instability, and ultimately cancer. Inhibitor of DNA‐binding 3 (ID3), a transcriptional repressor, is crucial to promoting DSB repair and helping maintain genome stability. Here, the authors investigated ID3 regulation of DNA repair via chromatin accessibility

RAGE Re‐Expressed at Myofibre Level Drives Muscle Wasting in Cancer Conditions

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 3, June 2026.
ABSTRACT Background Cancer cachexia (CC) is a highly debilitating syndrome characterized by loss of body and muscle weight affecting most advanced cancer patients. The receptor for advanced glycation end‐products (RAGE) is expressed by several cell types and sustains the inflammatory response in acute and chronic diseases. Total ablation of RAGE (Ager−/

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

DNA recognition, cleavage, and toxic metal ion interaction of an artificial zinc finger protein inside E. coli cells

open access: yesProtein Science, Volume 35, Issue 6, June 2026.
Abstract Zinc finger proteins are essential for the proper functioning of eukaryotic organisms, while their artificial variants can be used in cancer therapy or gene editing via their specific DNA recognition. Zn(II) binding is indispensable for the structural integrity of zinc fingers.
