(Cystadenocarcinoma, Mucinous...) :
EGF and TGF-alpha up-regulated thymidine phosphorylase ( dThdPase ) expression of tumor cells and consequently enhanced the antiproliferative action of 5'-dFUrd, which is converted to 5-fluorouracil by dThdPase

:
Forskolin, 12-O-tetradecanoylphorbol-13-acetate, and epidermal growth factor had no effect on the in vivo phosphorylation of PD-ECGF
