Figure 6From: Organic silicon protects human neuroblastoma SH-SY5Y cells against hydrogen peroxide effects Action of Si on caspase-8 activation mediated by H 2 O 2 . (*)/ns = Statistical significances referred to the basal values. ns = no significant, (*) = p < 0.05, (**) = p < 0.01 and (***) = p < 0.001. (●) = Statistical significances between H2O2 in absence and presence of silicon G5. (●●●) = p < 0.001.Back to article page
