WebJun 10, 2013 · TS is a key enzyme in the synthesis of DNA and the target enzyme of 5-FU. Several studies demonstrate that the expression levels of TS in the tumoural tissue predicts overall survival for colon cancer and correlates with resistance to 5-FU , . Acquired resistance to 5-FU is caused by overproduction of TS resulting from gene amplification. WebThe precise mechanism of action has not been fully determined, but the main mechanism of fluorouracil is thought to be the binding of the deoxyribonucleotide of the drug (FdUMP) and the folate cofactor, N5–10-methylenetetrahydrofolate, to thymidylate synthase (TS) to form a covalently bound ternary complex.
