Stem cell divisions, somatic mutations, cancer etiology, and cancer prevention March 24, 2017 (Science)

There are at least four sources of R mutations in normal cells: quantum effects on base pairing (30), mistakes made by polymerases (31), hydrolytic deamination of bases (32), and damage by endogenously produced reactive oxygen species or other metabolites (33). The last of these could theoretically be reduced by the administration of antioxidant drugs (34). The effects of all four could, in principle, be reduced by introducing more efficient repair genes into the nuclei of somatic cells or through other creative means.

Reported as: New Study Finds That Most Cancer Mutations are Due to Random DNA Copying ‘Mistakes’

John Hopkins Kimmel Cancer Center scientists report data from a new study providing evidence that random DNA copying “mistakes” account for nearly two-thirds of the mutations that cause cancer. Their research is grounded on a novel mathematical model based on DNA sequencing and epidemiologic data from around the world.
