In current study, we have investigated the anti-oral cancer effects of developed functional beverage, which integrates fucoidan complex (FC) with natural/organic ingredients including vegetable juice (V), mulberry (M) and wheatgrass (W), designated as VMW-FC cocktail. FC has been recognized as functional food with nutraceutical characteristics, other cocktail components are known to individually contain luxuriant bioactive factors including sulfated polysaccharides and polyphenols etc., exerting various curative impacts. Our results demonstrated that VMW-FC significantly inhibited oral cancer proliferation in a dose- and time-dependent manner. It also retarded cell cycle regulators (CDKs and cyclins) and upregulated cyclin-dependent kinase inhibitor p21. Additionally, VMW-FC suppressed cell migration along with inhibited EMT markers. Further, VMW-FC significantly attenuated xenograft tumor growth in NOD-SCID mice without further adverse effects. Conclusively, VMW-FC strongly inhibits oral cancer through inducing apoptosis, G2/M cell cycle arrest and reducing migration-related EMT markers, which may be primarily attributed to sulfated polysaccharides in beverage cocktail.
