Activity of thymidylate synthetase, thymidine kinase and galactokinase in primary and xenografted human colorectal cancers in relation to their chromosomal patterns.
Although the number of patients is relatively small, these results identify p53 status and TS gene expression as associated with response in disseminated colorectal cancer; independent studies are needed to confirm these findings and to provide information leading to a better understanding of the role of 5-FU-based chemotherapy in the treatment of colorectal cancer.
Arsenic trioxide (ATO) has been shown to suppress thymidylate synthase (TYMS) in lung adenocarcinoma and colorectal cancer, and induce apoptosis in acute promyelocytic leukemia.
Associations between polymorphisms in the thymidylate synthase gene, the expression of thymidylate synthase mRNA and the microsatellite instability phenotype of colorectal cancer.
Based on these data, we investigated whether patient's gender and TS polymorphism exert an interactive effect on the clinical evolution of patients with advanced colorectal cancer (CRC) subjected to 5 fluorouracil (5FU)-based adjuvant chemotherapy.
Chronic exposure of colorectal cancer cells in culture to fluoropyrimidine analogs induces thymidylate synthase and suppresses p53. A molecular explanation for the mechanism of 5-FU resistance.
Combination of polymorphisms within 5' and 3' untranslated regions of thymidylate synthase gene modulates survival in 5 fluorouracil-treated colorectal cancer patients.
Comparative analysis of thymidylate synthase, thymidine phosphorylase and dihydropyrimidine dehydrogenase expression in colorectal cancer and surrounding normal tissue.
Correlations to histopathological parameters and clinical follow-up revealed an association of TP, DPD and TS mRNA expression patterns with tumor stage and suggested new prognostic and predictive markers for patients with colorectal cancer.
Danenberg tumor profile method (DTP) was used in order to measure mRNA expression levels of thymidylate synthase (TYMS), dihydropyrimidine dehydrogenase (DPYD), and thymidine phosphorylase (TYMP) from 180 patients with colorectal cancer.
Dihydropyrimidine dehydrogenase and thymidylate synthase polymorphisms and their association with 5-fluorouracil/leucovorin chemotherapy in colorectal cancer.
Expression of thymidylate synthase (TS) and the 5-fluorouracil (5-FU) metabolic enzymes, including dihydropyrimidine dehydrogenase (DPD), orotate phosphoribosyl transferase (OPRT), thymidine phosphorylase (TP), and uridine phosphorylase (UP), has been reported to be associated with the sensitivity to 5-FU-based chemotherapy in colorectal cancer.
Floxuridine (5'-fluorodeoxyuridine, FUdR) acts as an inhibitor of DNA replication by binding to thymidylate synthase and is widely used to treat colorectal cancer.
Furthermore, we wanted to evaluate the interaction between MTHFR and thymidylate synthase (TS) and folylpolyglutamate synthase (FPGS) and to investigate the impact of folate concentration on patients with CRC with different MTHFR genotypes.
