Cancer-driving MYC protein also helps tumors repair damaged DNA

https://www.news-medical.net/news/20260517/Cancer-driving-MYC-protein-also-helps-tumors-repair-damaged-DNA.aspx A protein best known for driving cancer growth also helps damaged tumor cells survive by repairing their DNA, according to a new study that could influence how some cancers are treated. Researchers at Oregon Health & Science University found that the protein MYC, which is overactive in most human cancers, plays a direct role in fixing dangerous breaks in DNA. By helping cancer cells survive chemotherapy and other treatments that damage DNA, the protein may contribute to tumor resistance and poor patient outcomes.
