Antiproliferative effect of neomycin in glioma cells

The angiogenic growth factor (AGF) family of signaling molecules has been implicated in normal development and in physiological process as well as in human malignancy. Since blockage of nuclear translocation of AGF in endothelial cells with neomycin resulted in inhibition of the growth factor capacity to induce angiogenesis, we treated glioma cells with neomycin and assessed its effects on cell proliferation. Administration of 10 mM neomycin during two days resulted in a 56% inhibition of glioma cells proliferation. This result may provide the basis for the development of a novel adjuvant therapeutic strategy for gliomas.
