5-Fluorouracil treatment induces characteristic T>G mutations in human cancer

Abstract

5-Fluorouracil (5-FU) is a commonly used chemo drug to treat cancer patients. Using in vitro 5-FU treated organoids and in vivo 5-FU treated human cancer data, the authors describe a 5-FU mutational signature that is similar to COSMIC signature 17 frequently observed in untreated cancers
