There were significant differences between the groups in terms of thymidine kinase levels, with highest levels in the EGb761 and FK506 groups, followed by the EGb761 + FK506 group (p<0.05) (Table 3).
Studies about thymidine phosphorylase and thymidylate synthase concluded that the expression of these markers could be associated with response to just chemotherapy in rectal cancers, with no considerations about survival differences.

Thus, depending on the structure and concentration, the cited 1,4-DHP derivatives variously affected thymidine incorporation, cell proliferation, and growth, connected with OS and other metabolic influences.
Thymidine kinase-1 (TK1) is internationally recognized as a marker of abnormal cell proliferation, which enables the dynamic monitoring of the proliferation of cancer cells and can indicate tumor recurrence and metastasis.[sup][16] TK1 is usually detected using a chemiluminescence dot blot assay.[sup][16]

It is activated by thymidine phosphrylase enzyme into fluorodeoxyuridylate (5-fluoro-2'deoxyuridine-5'monophosphate, or 5-FdUMP) which inhibits thymidylate synthase, thus preventing deoxyribonucleic acid (DNA) synthesis.2 The concentration of thymidine phosphorylase is 3-10 folds higher in tumour cells compared to its concentration in the healthy tissues, and this can enable selective drug activation of 5-FU at the tumour site with limitation of systemic toxicity.3
