Catalase is an antioxidant enzyme the activity of which is crucial for the protection against damage caused by reactive oxygen species. The -262C>T polymorphism in the promoter region of catalase gene was found to be associated with altered catalase levels. In this study, peripheral blood mononuclear cells catalase activity was measured after H(2)O(2)-induced oxidative stress. C/T and T/T genotypes were associated with the decrease of catalase levels in contrast to C/C donors who had elevated catalase activity in the presence of 0.4 and 0.7 mM H(2)O(2). Genotype-dependent response of catalase activity to oxidative stress might be related to the predisposition of catalase mutant allele carriers to disorders mediated by oxidative stress.
