There was no significant difference in CAT activity at the polyphenol doses between MetS and healthy animals (3.62 ± 0.94 kU/mg and 3.90 ± 0.29 kU/mg for MetS+100 vs. HC+100, p = 0.609 and 3.31 ± 0.86 kU/mg and 3.51 ± 0.85 kU/mg for MetS+200 vs. HC+200, p = 0.547). The gene discussed is CAT; the disease is metabolic syndrome.
