Abstract:
:The effects of DL-alpha-difluoromethylornithine (DFMO), a specific irreversible inhibitor of ornithine decarboxylase, on the growth of experimental mouse B16-F10 melanoma cells were investigated. DFMO (3%) in drinking water was administered to B16-F10 melanoma-bearing mice. At 24 days, B16-F10 melanomas in DFMO-fed mice weighed 75% less than those in control mice (p less than 0.001). DFMO reduced putrescine and spermidine levels in B16-F10 melanoma by 98% and 84%, respectively, and prolonged the mean survival time from 25.9 +/- 1.2 to 35.7 +/- 2.2 days (p less than 0.001). The effects of DFMO on experimental metastasis were also investigated. DFMO treatment resulted in a significant decrease in pulmonary metastasis induced by i.v. injection of B16-F10 melanoma cells.
