Elevated dNTP Pool Levels Impair Homologous Recombination and Enhance Glioblastoma Sensitivity to Irradiation and Temozolomide
It is demonstrated that increasing deoxyribonucleoside triphosphate (dNTP) levels impairs HR-mediated double-strand break repair, rendering GBM cells sensitive to IR and Temozolomide and uncovering a promising vulnerability that could be exploited to overcome resistance to DNA-damaging treatments in GBM and beyond.
