['Angiogenin undergoes nuclear translocation and stimulates ribosomal RNA transcription in both endothelial and cancer cells. Consequently, angiogenin has a dual effect on cancer progression by inducing both angiogenesis and cancer cell proliferation. The aim of this study was to assess whether neamine, a blocker of nuclear translocation of angiogenin, possesses antitumor activity toward oral cancer.', 'The antitumor effect of neamine on oral cancer cells was examined both in vitro and in vivo.', 'Neamine inhibited the proliferation of HSC-2, but not that of SAS oral cancer cells in vitro. Treatment with neamine effectively inhibited growth of HSC-2 and SAS cell xenografts in athymic mice. Neamine treatment resulted in a significant decrease in tumor angiogenesis, accompanied by a decrease in angiogenin- and proliferating cell nuclear antigen-positive cancer cells, especially of HSC-2 tumors.'] Does neamine inhibit oral cancer progression by suppressing angiogenin-mediated angiogenesis and cancer cell proliferation?
