Descripción general
Thymidine phosphorylase inhibits vascular smooth muscle cell proliferation.
Aplicación
Thymidine phosphorylase has been used in a study to evaluate biomarkers for advanced breast cancer patients treated with capecitabine-based first-line chemotherapy. Thymidine phosphorylase has also been used in a study to investigate implications for the clinical efficacy of nucleoside analogues.
Acciones bioquímicas o fisiológicas
An enzyme that catalyzes the reversible conversion of thymidine to thymine. Thymidine phosphorylase is part of the pyrimidine nucleoside salvage pathway. This pathway allows pyrimidine bases to be recycled for nucleotide biosynthesis, while the pentose 1-phosphates are converted to intermediates of the pentose phosphate shunt and glycolysis. The E. coli thymidine phosphorylase shares 40% sequence homology with the human sequence, which has been found to be identical to the angiogenic agent platelet-derived endothelial growth factor. The purified E. coli enzyme has been shown to stimulate blood vessel growth in chick chorioallantoic membrane assays.
Definición de unidad
One unit will convert 1.0 μmole each of thymidine and phosphate to thymine and 2-deoxyribose 1-phosphate per min at pH 7.4 at 25°C.

Several anti-angiogenic agents have been developed and some of them have been clinically applied in the tumor therapy. Anti-angiogenic therapy faces some hurdles: inherent or acquired resistance, increased invasiveness, and lack of biomarkers. Characterization of tumor endothelial markers may help

Human thymidine phosphorylase (HTP), also known as platelet-derived endothelial cell growth factor (PD-ECGF), is overexpressed in certain solid tumors where it is linked to poor prognosis. HTP expression is utilized for certain chemotherapeutic strategies and is also thought to play

The aim of the present study was to investigate the gene expression of biomarkers associated with the sensitivity to fluoropyrimidine and taxanes in recurrent/advanced breast cancer patients treated with first-line capecitabine chemotherapy. We evaluated the clinicopathological/prognostic significance of thymidylate synthase

Erythrocyte-encapsulated thymidine phosphorylase (EE-TP) is currently under development as an enzyme replacement therapy for mitochondrial neurogastrointestinal encephalomyopathy (MNGIE), an autosomal recessive disorder caused by a deficiency of thymidine phosphorylase. The rationale for the development of EE-TP is based on the
