TNF-alpha induces UPase gene expression and enhances cell sensitivity to 5'-DFUR

Published in Vaccine Weekly, May 24th, 2006

TNF-alpha induces uridine phosphorylase (UPase) gene expression and enhances cell sensitivity to 5'-deoxy-5-fluorouridine (5'-DFUR).

"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'-DFUR into 5-FU. In this study, we investigated the effect of tumor necrosis factor-alpha (TNF-alpha) on UPase gene expression and 5'-DFUR antiproliferative activity and elucidated the involved signal transduction pathway," scientists in the United States reported.

"Our data indicate that TNF-alpha significantly induced UPase mRNA...
