Ultraviolet light from the sun is a ubiquitous carcinogen that can inflict structural damage to the cellular DNA. It is one of the oldest known source of gene mutation.
Failure in removing and restoring damaged parts of DNA in a timely fashion can have detrimental outcomes and lead to skin cancers.
A breakthrough study, led by the Min Research Group and Dr. Jung-Hyun Min, has garnered a better understanding of how sunlight-induced DNA damage is initially recognized for repair in cells.
Dr. Min joins Dr. Roizen to discuss the study's findings. She also shares some of the other causes of DNA structural damage, including free radicals (pollution, cigarette smoke, red meat, grilled meats).
