Polaprezinc protects human colon cells from oxidative injury induced by hydrogen peroxide: Relevant to cytoprotective heat shock proteins

Figure 1 Effect of polaprezinc on up-regulation of heat shock protein HSP27 and HSP70 in CaCo2 cells. The expression of HSP27 and HSP72 was markedly up-regulated in the CaCo2 cells treated with polaprezinc. Representative results of three complete experiments are shown.

Figure 2 Effect of quercetin on induction of HSP27 and HSP72 in CaCo-2 cells treated with polaprezinc. Quercetin did not up-regulate the expression of HSP27 and HSP72 in the cells. Representative results of three complete experiments are shown.
