Direct evidence of singlet molecular oxygen [O2 (1Δg)] production from UVA excited 6‐thioguanine

Photochemistry and Photobiology, EarlyView.
6‐Thioguanine (6‐TGua) is incorporated into DNA as a purine analogue, inhibiting cell replication. Patients treated with 6‐TGua are more prone to developing skin cancer due to the photoexcitation of 6‐TGua by UVA radiation (as illustrated in the Jablonski diagram). Upon exposure to UVA, the excited 6‐TGua generates 1O2.

On why cancer cells require a great amount of glucose

Quantitative Biology, Volume 14, Issue 2, June 2026.
Abstract The traditional thinking has been that cancer cells require a great amount of glucose to support their rapid growth, but the reality may be different. We have previously demonstrated that all cancer cells in The Cancer Genome Atlas harbor persistent Fenton reactions in their cytosol, which generate OH− ${\text{OH}}^{-}$ and ultimately kill the

Advances in Wine Yeast Autolysis: Biochemical and Molecular Mechanisms, and the Release of Organic Compounds in White and Sparkling Wines—An Updated Review

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT Wine yeasts play a central role in alcoholic fermentation and significantly contribute to the sensory attributes of wines through cellular autolysis during lees aging (sur lie), especially in white wines. This process releases organic compounds that alter the wine's chemical and sensory profile.

Dysregulation of CD39/Ectonucleoside Triphosphate Diphosphohydrolase 1 Causes Urinary Bladder Dysfunction with Abnormal Smooth Muscle Contractility

The FASEB Journal, Volume 40, Issue 7, 15 April 2026.
Abnormal extracellular ATP levels cause lower urinary tract symptoms (LUTS). Here, we demonstrate that overexpression of ENTPD1 (CD39TG)—an ATP/ADP converting enzyme—reduces voiding frequency while increasing void volume. Conversely, ENTPD1 deficiency results in frequent, small‐volume voiding.

Clinical Pharmacogenetics Implementation Consortium (CPIC) Guideline for Thiopurine Dosing Based on TPMT and NUDT15 Genotypes: 2025 Update

Clinical Pharmacology &Therapeutics, Volume 119, Issue 4, Page 916-927, April 2026.
Thiopurine methyltransferase (TPMT) and Nudix hydrolase 15 (NUDT15) are key enzymes that catabolize thiopurines. Decreased or no‐function alleles in TPMT and NUDT15 are associated with reduced or no enzyme activity and predictive of pronounced adverse effects, including severe myelosuppression, that may occur among individuals treated with standard ...

Deficient Cardiolipin Remodelling Alters Muscle Fibre Composition and Neuromuscular Connectivity in Barth Syndrome

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 2, April 2026.
ABSTRACT Background Barth syndrome (BTHS) is a rare X‐linked mitochondrial disorder caused by mutations in the TAFAZZIN gene, which disrupts cardiolipin (CL) remodelling and mitochondrial function. While cardiac manifestations of BTHS are well characterized in male patients, the mechanisms underlying skeletal muscle weakness and fatigability are poorly
