Abstract excerpt
Thymidylate synthase is a target enzyme for chemotherapeutic agents such as 5-fluorouracil and capecitabine, its oral prodrug. The human thymidylate synthase gene promoter is polymorphic, having either double or triple repeats of a 28-bp sequence. It has previously been shown that colorectal cancer patients who are homozygous for the triple tandem repeats (L/L) have significantly higher thymidylate synthase mRNA...
