| Background | The methylation of deoxyuridine monophosphate (dUMP) to deoxythymidine monophosphate (dTMP) is an essential step in the formation of thymine nucleotides (1,2, reviewed in 3). This process is catalyzed by thymidylate synthase (TS or TYMS), a homodimer composed of two 30 kDa subunits. TS is an intracellular enzyme that provides the sole de novo source of thymidylate, making it a required enzyme in DNA biosynthesis with activity highest in proliferating cells (1). Being the exclusive source of dTMP, investigators have concluded that TS is also an important target for anticancer agents such as 5-fluorouracil (5-FU) (1-5). 5-FU acts as a TS inhibitor and is active against solid tumors such as colon, breast, head, and neck. Research studies have demonstrated that patients with metastases expressing lower levels of TS have a higher response rate to treatment with 5-FU than patients with tumors that have increased levels of TS (5). Researchers continue to investigate TS expression in different types of cancers (6-10).Levels of thymidylate synthase can be modultated in vitro by treatment with various drugs, such as 5-FU and lapatinib. 5-FU treatment induces the formation of two distinct bands, one at 35 kDa and another at 38 kDa, while lapatinib treatment results in a decrease in thymidylate synthase expression (11,12). |
