Figure Lengend Snippet: Combination therapy with EGCG plus FA dampens neuroinflammation and oxidative stress. Data were obtained from APP/PS1 mice that received vehicle ( APP/PS1-V , n = 8), EGCG ( APP/PS1-EGCG , n = 8), FA ( APP/PS1-FA , n = 8), or EGCG plus FA ( APP/PS1-EGCG/FA , n = 8) for 3 months commencing at 12 months of age (mouse age at sacrifice = 15 months). Data for A and B additionally included WT mice treated in parallel with vehicle ( WT-V , n = 8), EGCG ( WT-EGCG , n = 8), FA ( WT-FA , n = 8), or EGCG plus FA ( WT-EGCG/FA , n = 8). Data for A and B as well as D and E are presented as standard deviations of the means. QPCRs are shown for tumor necrosis factor-α ( TNF -α) or interleukin-1β (IL-1 β) proinflammatory cytokines or for key oxidative stress markers superoxide dismutase 1 ( SOD1 ) or GSH peroxidase 1 ( GPx1 ). Data for A and B are expressed as relative fold over WT-V mice. C , Western blots are shown using anti-Cu/Zn SOD polyclonal antibody ( pAb SOD1 ) or by anti-GPx1 polyclonal antibody ( pAb GPx1 ). Western blots included each mouse ( n = 8 per group), and quantitative data were averaged. Ten μg of protein from each sample was equally loaded per lane. Actin is included as a loading control for each appropriate blot, and densitometry data are shown below each lane. Densitometry data are shown for ratios of SOD1 to actin ( D ) or for GPx1 to actin ( E ). Statistical comparisons for A and B are between-groups but within each mRNA species. Statistical comparisons for D and E are within each protein but between-groups. *, p
