Figure 1From: Paraoxonase 1 polymorphism Q192R affects the pro-inflammatory cytokine TNF-alpha in healthy malesEffect of the PON1 Q192R polymorphism on serum PON1 enzyme activity. PON1 activity was determined in the sera of Q/Q (n = 25) and Q/R+R/R (n = 24) male individuals under standard assay conditions using paraoxon as substrate. Data represent means ± SEM (*** p ≤ 0.001).Back to article page
