Expression of NT proteins is apparently redundant in most cell types, and the elucidation of their particular physiological roles still remains elusive. Moreover, transporter-mediated uptake of nucleoside-derived anticancer drugs is crucial for the pharmacogenomic response triggered by these molecules in tumor cells. This review focuses on recent data demonstrating that nucleoside transporters, particularly CNTs, can play physiological roles other than salvage, whereas particular NT isoforms can significantly contribute to the transcriptomic response triggered by nucleoside analogs in cancer cells. | | Language | ENG | | Pub Type(s) | JOURNAL ARTICLE
