The anti-cancer effects of the different plant polysaccharides have sometimes been proposed to be mediated by extracellular galectin activities such as cell adhesion (1, –, 6, 8, 9, 12, –, 14, 17, –, 19, 38) but also by intracellular effects such as the intracellular anti-apoptotic effect of galectin-3 (6, 10). Here, LGALS3 is linked to cancer.
