Pediatric Dermatology, EarlyView.ABSTRACT The rubella virus vaccine strain can cause granulomas in patients with inborn errors of immunity that may evolve into chronic, recalcitrant ulcers. This report details treatment of ulcerated rubella granulomas in a patient with ataxia telangiectasia with doxycycline and hydroxychloroquine resulting in partial ulcer healing within 4 weeks ...

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

Mre11 assembles linear DNA fragments into DNA damage signaling complexes.
PLoS Biology, 2004 Mre11/Rad50/Nbs1 complex (MRN) is essential to suppress the generation of double-strand breaks (DSBs) during DNA replication. MRN also plays a role in the response to DSBs created by DNA damage.

Born early, age fast: Consequences of premature birth on chronic disease and accelerated ageing
The Journal of Physiology, EarlyView.Abstract figure legend ELGANs are exposed to several postnatal pro‐oxidant stressors, including ambient and supplemental oxygen, mechanical ventilation, infections, hyperalimentation, excessive glucocorticoids and intermittent hypoxia. Since endogenous antioxidant defences are underdeveloped, this imbalance promotes oxidative stress and inflammation ...

The Role of Hematopoietic Cell Transplantation in Ataxia‐Telangiectasia
Pediatric Blood &Cancer, Volume 73, Issue 8, August 2026.ABSTRACT Background Ataxia‐telangiectasia (A‐T) is a DNA repair disorder characterized by neurodegeneration, immunodeficiency, and cancer predisposition. Hematopoietic cell transplantation (HCT) is an established therapy in related disorders such as Fanconi anemia (FA) and Nijmegen breakage syndrome (NBS), but its role in A‐T is unclear.

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 ...
