Abstract
Fibroblast growth factors (FGFs) are powerful angiogenic polypeptides that are involved in the autocrine growth stimulation of gliomas. We report here that addition to glioma cell cultures of 1,3,6-naphthalenetrisulfonate (NTS), an inhibitor of the mitogenic activity of FGFs, significantly enhanced apoptosis, as assessed by terminal deoxynucleotidyl transferase (TdT) assay. The pro-apoptotic effect of NTS was time-dependent. These findings suggest that FGF may play a pivotal role in the survival of glioma cells, and support a clinical interest of NTS as a leading compound for the development of new antitumorals.
