Abstract excerpt
Thymidylate synthase (TS), a key one-carbon metabolizing gene, encodes an enzyme that converts dUMP to dTMP, the rate-limiting nucleotide in DNA synthesis. We recently reported that a promoter polymorphism in TS modified the risk of colorectal cancer as well as the survival rate after the disease. To explore whether TS may play an important role in colorectal carcinogenesis early in the multistaged pathogenic...
