The use of the well-known powerful antioxidant ascorbate has recently become more widespread in human medicine. Intravenous administration of high-dose ascorbate has been demonstrated to exert anticancer effects. It has resulted in effective cell death in vitro and inhibition of tumour growth in vivo. The aim of the current study was to evaluate the effects of high-dose ascorbate on canine melanoma in vitro. Four canine melanoma cell lines, UCDK9M1, UCDK9M3, UCDK9M4 and UCDK9M5 were treated with ascorbate for 2 hours at a range of millimolar concentrations (0-20 mM) to investigate the resulting effects on cell viability. All four canine melanoma cell lines exhibited reduced viability in a dose-dependent manner. Further investigation demonstrated that high-dose ascorbate induced apoptosis via the activation of Bax. These findings suggest that high-dose ascorbate has an anticancer effect on canine melanoma cell lines in vitro. With regard to clinical application, further in vivo investigation should be conducted.
