Cytoprotective Mechanisms Mediated by Polyphenols from Chilean Native Berries against Free Radical-Induced Damage on AGS Cells

Figure 5

Effect of the PEE from F. chiloensis on oxidative stress markers. (a) and (b) Western blots showing the levels of carboxymethyl lysine (CML) in proteins from AGS cells co- and preincubated and challenged with peroxyl radicals (AAPH, 168 mM), respectively. (c) Densitometric analysis of CML levels obtained from the Western blots. (d) and (e) Thiobarbituric acid reactive substances expressed as malondialdeyde concentration (nmol/mg protein) in AGS cells co- and preincubated with the PEE from F. chiloensis and challenged with peroxyl radicals (AAPH, 168 mM).
