Thymidine Phosphorylase and Dihydropyrimidine Dehydrogenase in Bladder Cancer
Urologia Internationalis, 2002Thymidine phosphorylase (TP) and dihydropyrimidine dehydrogenase (DPD) levels in transitional cell carcinoma of the bladder resected from 38 patients were examined by ELISA. TP levels in high-grade and invasive cancer were significantly higher than those in low-grade and superficial cancer, respectively.

Expression of thymidine phosphorylase and cyclooxygenase-2 in melanoma
Melanoma Research, 2013Several studies have reported an increase in vascular structures in malignant melanoma. Neovascularization can be enhanced by several factors. Among them, thymidine phosphorylase (TP) and cyclooxygenase-2 (COX-2) have been reported to play a role. The expressions of TP and COX-2 were evaluated trough immunohistochemistry in a series of 78 primary ...

Localization of thymidine phosphorylase in breast cancer tissue
Medical Molecular Morphology, 2005Thymidine phosphorylase levels are higher in some human cancer tissues than in adjacent normal tissue. However, the ultrastructural localization of thymidine phosphorylase in cancer tissue has been demonstrated only in advanced gastric and colorectal cancer.

Substrate specificity of Escherichia coli thymidine phosphorylase
Biochemistry (Moscow), 2007Substrate specificity of Escherichia coli thymidine phosphorylase to thymidine derivatives modified at 5' -, 3' -, and 2' ,3' - positions of the sugar moiety was studied. Equilibrium and kinetic constants (K(m), K(I), k(cat)) of the phosphorolysis reaction have been determined for 20 thymidine analogs.

[Thymidine phosphorylase and angiogenesis].
Gan to kagaku ryoho. Cancer & chemotherapy, 2000Thymidine phosphorylase (TP) is identical to platelet-derived endothelial cell growth factor (PD-ECGF). TP has an angiogenic activity and confers resistance to hypoxia-induced apoptosis on cells. TP expression is correlated with microvessel count, invasion and poor prognosis in many solid tumors.

[Expression of thymidine phosphorylase in cancer].
Zhonghua zhong liu za zhi [Chinese journal of oncology], 2005To study the thymidine phosphorylase (TP) expression in different types of cancer and its correlation with tumor microvessel density (MVD).The expression of TP and MVD was detected by immunohistochemistry method. In a series of 251 cancer patients there were 48 patients with gastric cancer, 53 with colorectal cancer, 47 with breast cancer, 56 with ...

Thymidine phosphorylase and breast carcinoma.
Anticancer research, 2002Thymidine phosphorylase (TP), also known as platelet-derived endothelial-cell growth factor (PD-ECGF), is an enzyme that catalyzes the reversible dephosphorylation of thymidine, deoxyguridine and their analogs. TP also has angiogenic properties, although the precise mechanism by which it promotes angiogenesis is not known.
