BACKGROUND: 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.
MATERIALS AND METHODS: The antitumor effect of neamine on oral cancer cells was examined both in vitro and in vivo.
RESULTS: 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.
CONCLUSION: Neamine effectively inhibits oral cancer progression through inhibition of tumor angiogenesis. Neamine also directly inhibits proliferation of certain types of oral cancer cells. Therefore, neamine has potential as a lead compound for oral cancer therapy.
