Methotrexate Toxicity in a Patient With Renal Failure Despite a Normal Methotrexate Concentration: A Case Report and Literature Review

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Methotrexate (MTX) is a folate antagonist widely used as a disease‐modifying antirheumatic drug (DMARD) in rheumatoid arthritis (RA), as well as in several malignancies and autoimmune disorders. Although low‐dose MTX (5–20 mg/week) is generally considered safe, it has a narrow therapeutic index, and toxicity can occur even at therapeutic doses,

Inducible CRISPR/Cas systems in precision oncology: Current applications and future perspectives

Clinical and Translational Medicine, Volume 16, Issue 6, June 2026.
Inducible CRISPR/Cas systems enable spatiotemporal genome editing in precision oncology. Chemical, optical, physical, and microenvironmental stimuli provide distinct control strategies. Conditional activation may reduce off‐target exposure and basal nuclease activity.

Unveiling the Connection: Viral Infections and Genes in dNTP Metabolism

Viruses
Deoxynucleoside triphosphates (dNTPs) are crucial for the replication and maintenance of genomic information within cells. The balance of the dNTP pool involves several cellular enzymes, including dihydrofolate reductase (DHFR), ribonucleotide reductase (

Synergistic Enhancement: Whole Wheat Substrate Improves Memory in Mice by Optimizing Folate Metabolism and Systemic Antioxidant Capacity

Food Bioengineering, Volume 5, Issue 2, Page 244-258, June 2026.
ABSTRACT This study rigorously assessed the impact of folic acid‐fortified whole wheat products on mitigating mild liver injury caused by prolonged excessive folic acid consumption, improving folic acid bioavailability, and enhancing spatial cognitive functions in mice over a 48‐day intervention period.

Dihydrofolate reductase as a model for studies of enzyme dynamics and catalysis [version 1; referees: 2 approved]

F1000Research, 2015
Dihydrofolate reductase from Escherichia coli (ecDHFR) serves as a model system for investigating the role of protein dynamics in enzyme catalysis. We discuss calculations predicting a network of dynamic motions that is coupled to the chemical step ...

Harnessing Trace Elements: Novel Radiosensitization Strategies for Enhanced Cancer Radiotherapy

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Radiotherapy (RT) is one of the core methods of comprehensive cancer treatment. Globally, more than 40% of cancer patients rely on radiotherapy to achieve tumor control, cure or palliative relief. However, radiation resistance, immunosuppression and normal tissue injury limit its clinical application.
