Fucoidan is a sulfated polysaccharide that is purified from brown algae, such as Fucus vesiculosus. This compound has multiple biological activities including immune-stimulating, and anti-viral activities. We recently demonstrated that the cytotoxicity of fucoidan can be dependent on the batch of its production and its molecular weight. In a previous study, fucoidan B exerted cytotoxicity toward mouse spleen cells. To confirm the biological activity of Fucoidan B, we cultured HL-60 cells, a human leukemia cell line, and treated then with fucoidan. The metabolic activity of the HL-60 cells decreased in response to treatment by fucoidan. Moreover, the morphology of HL-60 treated by fucoidan changed. To investigate the fucoidan’s effects, we analyzed the size and level of Annexin V/propidium iodide staining of HL-60 cells using a flow cytometer. Fucoidan consistently induced cell death, including apoptosis of HL-60 cells. As potential mechanisms, fucoidan destabilized the mitochondrial membrane potential and altered the production of reactive oxygen species in HL-60 cells. Taken together, these results suggest that fucoidan has anti-tumor activity on HL-60 cells via destabilization of mitochondrial membrane potential. The present study demonstrates that fucoidan can be used as an anti-cancer agent for leukemia.
