Abstract
Somatic mutations have traditionally been associated with cancer, yet more recently, it was realized that they also appear in nontransformed cells beginning in early life. Remarkably, some of these mutations, commonly viewed as cancer driver mutations, are widely spread among cells of noncancerous tissues, sometimes affecting the majority of the tissue cells. This spreading process intensifies upon aging or exposure to extrinsic insults, such as UV irradiation, inhaling smoke, and inflammatory cues. Whereas classic driver mutations in normal cells are mostly viewed as a first step in the carcinogenesis process, here, we speculate that in certain states, they can play beneficial homeostatic roles while confronting stress and aging tissue repair.
