Outline of Final Research Achievements |
Thymidine phosphorylase (TP) is an angiogenic growth factor; it catalyzes the reversible phosphorylation of thymidine to thymine. TP is overexpressed in highly malignant cancers. To identify the cancer malignancy or predict therapeutic effects of anticancer drugs based on the thymidine analog in relation to TP expression levels in tumors, we developed a radio-iodinated uracil derivative with TP inhibitory potency. Here, we elucidated its uptake mechanism into tumor cells and normal tissues based on the organic cation transporter. Our results could help advance reliability and applicability in cancer theranostics.
