MTH1 hydrolyzes oxidized nucleoside triphosphates, thereby sanitizing the nucleotide pool from oxidative damage. This prevents incorporation of damaged nucleotides into DNA, which otherwise would lead to mutations and cell death. The high level of reactive oxygen species in cancer cells leads to a higher level of oxidized nucleotides in cancer cells compared to that in nonmalignant cells, making cancer cells more dependent on MTH1 for survival ...
