Thiodigalactoside (TDG) as a non-metabolised drug, is shown to suppress tumor growth by inhibiting cancer enhancing activities of galectin-1, including immune cell dysregulation, angiogenesis and protection against oxidative stress. Using B16F10 melanoma and 4T1 orthotopic breast cancer models, intratumoral injection of TDG significantly raised the levels of infiltrating CD8(+) lymphocytes and reduced CD31(+) endothelial cell content, reducing tumor growth. TDG treatment of tumors in Balb/c nude mice reduced angiogenesis and slowed tumor growth by a third less than in immunocompetent mice. Knocking down galectin-1 expression (G1KD) significantly impeded tumor growth and the sensitivity of the G1KD tumors to TDG was severely reduced. Endothelial cells were protected by galectin-1 from oxidative stress-induced apoptosis, but TDG inhibited this antioxidant protective effect of galectin-1 and reduced tube forming activity.
