OBJECTIVE
The aim of the present study was to investigate regulatory mechanisms of angiogenesis in the decidua using immortalized human decidual fibroblasts.
METHODS
A sample of decidual fibroblasts was taken from a woman in early pregnancy. A cell line, DE-1, was established by infecting the

The angiogenic factor thymidine phosphorylase (TP) is highly expressed in human monocytes and macrophages, and its expression has been linked to the pathology and progression of solid tumors, rheumatoid arthritis, and gastric ulcers. In this study, TP mRNA and enzyme activity were found to be
Modulation of uridine phosphorylase gene expression by tumor necrosis factor-alpha enhances the antiproliferative activity of the capecitabine intermediate 5'-deoxy-5-fluorouridine in breast cancer cells.

Uridine phosphorylase (UPase) has been shown to play an important role in the antineoplastic activity of 5-fluorouracil (5-FU) and in the anabolism of its oral prodrug, capecitabine, through the conversion of 5'-deoxy-5-fluorouridine (5'-DFUR) into 5-FU. In this study, we investigated the effect of

Angiogenesis is an essential requirement for tumour growth and metastasis and is regulated by a complex network of factors produced by both stromal cells and neoplastic cells within solid tumours. The cytokine tumour necrosis factor alpha (TNF-alpha) and the enzyme thymidine phosphorylase (TP) are

Thymidine phosphorylase (TP; also known as platelet-derived endothelial cell growth factor, PD-ECGF) is an angiogenic factor that is chemotactic for endothelial cells and has been found to induce neovascularization in vivo. TP is frequently overexpressed in human solid tumors, where its expression

Gliostatin/thymidine phosphorylase (GLS/TP) is known to have angiogenic and arthritogenic activities. The purpose of this study was to determine the inhibitory effects of FK506 (tacrolimus) on GLS production in rheumatoid arthritis (RA). We investigated the modulation of serum GLS by FK506 therapy
Activation of Stat1, IRF-1, and NF-kappaB is required for the induction of uridine phosphorylase by tumor necrosis factor-alpha and interferon-gamma.

Thymidine phosphorylase (dThdPase) is an essential enzyme for the activation of the cytostatics capecitabine (N4-pentyloxycarbonyl-5'-deoxy-5-fluorocytidine) and its intermediate metabolite 5'-deoxy-5-fluorouridine (5'-dFUrd) to 5-fluorouracil (5-FUra) in tumors. We observed previously that several

Using a mouse cDNA probe we have identified a human uridine phosphorylase cDNA clone from the cDNA library of a human colorectal tumor cell line, HCT116. The recombinant human uridine phosphorylase expressed in COS-7 cells demonstrated specific enzyme activity with uridine as the substrate; this
Cytokines induce uridine phosphorylase in mouse colon 26 carcinoma cells and make the cells more susceptible to 5'-deoxy-5-fluorouridine.

Thymidine phosphorylase (dThdPase) is an angiogenic enzyme and seems to be related to an angiogenesis in human colorectal carcinoma. The incidence of dThdPase-positive cells was significantly correlated with microvessel count in 21 human colorectal carcinomas. Interleukin 1 alpha (IL-1 alpha), tumor
