Fig. 6.

The effect of 50 nM and 1 μM of VGVAPG and VVGPGA peptide, respectively, on a GPx, b SOD, and c CAT activity in the SH-SY5Y cell line after 48 h. The experiments were conducted after application of scrambled siRNA, GLB1 siRNA, or LGAL3 siRNA. Protein activity was normalized to the total protein level. Data are expressed as mean ± SD of three independent experiments, each of which consisted of six replicates per treatment group. *p < 0.05; ***p < 0.001 versus the scramble siRNA vehicle control. #p < 0.05; ##p < 0.01; ###p < 0.001 versus the GLB1 siRNA, or LGAL3 siRNA vehicle control
