PMID: 28977913
Oncotarget. 2017 Jun 28;8(37):61901-61916. doi: 10.18632/oncotarget.18717. eCollection 2017 Sep 22.

Previous studies have suggested that astrocyte-elevated gene-1 (AEG-1) contributes to the mechanisms of resistance to various chemotherapeutics. In this study, we investigated whether AEG-1 expression level correlated with that of thymidylate synthase (TS), as higher TS expression is known...

One major reason for the failure of advanced colorectal cancer (CRC) treatment is the occurrence of chemoresistance to fluoropyrimidine (FU)-based chemotherapy. Long non-coding RNA HOTAIR has been considered as a pro-oncogene in multiple cancers. However, the precise functional mechanism...

New agent development, mechanistic understanding, and combinatorial partnerships with known and novel modalities continue to be important in the study of pancreatic cancer and its improved treatment. In this study, known antimetabolite drugs such as gemcitabine (ribonucleotide reductase inhibitor)...

Alimta (pemetrexed) is a novel multitargeted antifolate that inhibits several enzymes in the de novo pathways of pyrimidine and purine biosynthesis, including thymidylate synthase, dihydrofolate reductase, and glycinamide ribonucleotide formyltransferase. Pemetrexed possesses antitumor activity in several solid tumors, including...

Predictive value of thymidylate synthase for the prognosis and survival of lung adenocarcinoma patients.

Oncol Lett. 2015 Jan;9(1):252-256. doi: 10.3892/ol.2014.2658. Epub 2014 Nov 03.

Chemotherapy represents an important treatment modality for lung adenocarcinoma. Thymidylate synthase (TS) is an essential enzyme in DNA synthesis, and its overexpression has been associated with reduced sensitivity to antifolate agents. The aim of the current study was to...

Trifluorothymidine exhibits potent antitumor activity via the induction of DNA double-strand breaks.

Experimental and therapeutic medicine

Exp Ther Med. 2011 May;2(3):393-397. doi: 10.3892/etm.2011.244. Epub 2011 Mar 21.

TAS-102 is an oral anticancer drug composed of trifluorothymidine (TFT) and TPI (an inhibitor of thymidine phosphorylase that strongly inhibits the biodegradation of TFT). Similar to 5-fluorouracil (5FU) and 5-fluoro-2'-deoxyuridine (FdUrd), TFT also inhibits thymidylate synthase (TS), a rate-limiting...
