Alginates are polysaccharides isolated from brown algae with gel-forming properties composed of 1,4-linked beta-D-mannuronic acid (M), alpha-L-guluronic acid (G), and alternating (MG) blocks. In this study, we have examined the toxic effects of high M-alginate to activate HepG2 human liver cells. Alginate enhanced the NO production and iNOS protein expression in HepG2 cells. In addition, alginates stimulated the HepG2 to induce IL-1 release and expression of TGF-beta1, which could influence the liver inflammation and chirrhosis. These findings suggest that high M-alginate form brown algae may have toxic effects on liver cells.
