Analysis of the Relationship between Antioxidant Enzyme Gene Polymorphisms and Their Activity in Post-Traumatic Gonarthrosis

Аннотация

Analysis of polymorphisms of genes encoding antioxidant enzymes SOD1 (G7958A), SOD2 (T58C), CAT (C-262T), and GSTP1 (Ile105Val) in 93 patients with post-traumatic gonarthrosis showed that GSTP1 Ile105Val polymorphism is often associated with heterozygous mutation in catalase gene CAT C-262T. In gonarthrosis, catalase activity in peripheral blood mononuclear cells in patients with CT genotype of the C-262T locus of CAT gene more than 2-fold surpassed that in CC genotype and more than 50% surpassed the normal. Changes in the balance of activity of antioxidant enzymes can affect viability of mononuclear cells.
