Ultraviolet light-induced mutation drives many skin cancers, researchers find
The mutation occurs in a gene called KNSTRN, which is involved in helping cells divide their DNA equally during cell division. Genes that cause cancer when mutated are known as oncogenes. Although KNSTRN hasn’t been previously implicated as a cause of human cancers, the research suggests it may be one of the most commonly mutated oncogenes in the world. “This previously unknown oncogene is activated by sunlight and drives the development of cutaneous squamous cell carcinomas,” said Paul Khavari, MD, PhD, the Carl J…
