Cím:Blood Catalase Activities, Catalase Gene Polymorphisms and Acatalasemia Mutations in Hungarian Patients with Diabetes Mellitus / Góth László, Nagy Teréz, Paragh György, Káplár Miklós

Megjegyzések:AbstractIntroduction: Catalase decomposes hydrogen peroxide into oxygen and water. Its low concentration could be involved in signaling while its high concentration is toxic.Aim: This short review discusses the association of blood catalase and diabetes mellitus in Hungarian diabetic patients.Results: Several cohort studies showed decreased blood catalase activity in type 2 diabetes and in gestational diabetes. Among the catalase gene polymorphisms rs769217 showed a weak association with type 1 diabetes. Regarding rs1001179 polymorphism patients with TT genotype have a risk for lower life expectancy. In acatalasemics the frequency of diabetes mellitus is higher (P?0.001) than in the Hungarian population. 11 of 12 known Hungarian acatalasemia mutations are found in diabetic patients. Acatalasemia may be associated with a higher risk for diabetes mellitus especially for its type 2 form.Acatalasemia mutations could explain the decreased (?50%) blood catalase activities only in 17.4% of the cases. Conclusions: Blood catalase activity is decreased in type 2 and gestional diabetes. Patients with inherited catalase deficiency and known acatalasemia mutation are at higher risk of diabetes mellitus.The lifelong effect of oxidative damage on the oxidant sensitive, insulin producing pancreatic beta-cells could contribute to the manifestation of diabetes mellitus especially to type 2 form.Acatalasemia mutations could explain the reason for the catalase decrease while for the other (82.6 %) cases it remains unsolved.The decreased blood catalase activity in type 2 and gestational diabetes rather due to regulatory mechanisms than to the catalase gene mutations

Cím:Effects of rs769217 and rs1001179 polymorphisms of catalase gene on blood catalase, carbohydrate and lipid biomarkers in diabetes mellitus / Góth László, Nagy Teréz, Kósa Zsuzsanna, Fejes Zsolt, Harjit Pal Bhattoa, Paragh György, Káplár Miklós

Megjegyzések:Oxidative stress and deficiency of the enzyme catalase, which is the primary scavenger of the oxidant H(2)O(2), may contribute to diabetes. The current study examined two polymorphisms in the catalase gene, -262C>nT in the promoter and 111C>T in exon 9, and their effects on blood catalase activity as well as on concentrations of blood glucose, haemoglobin A1c, triglyceride, cholesterol, HDL, LDL, ApoA-I and ApoB. Subjects were type-1 and type-2 diabetics. We evaluated PCR-single strand conformational polymorphism for 111C>T and PCR-restriction fragment length polymorphism for -262C>T. TT genotype frequency of 111C>T polymorphism was increased in type-1 diabetes. Type-2 diabetics with the CC or CT genotypes had decreased catalase and increased glucose, hemoglobinA1c and ApoB. Type-2 diabetics who have TT genotype in -262C>T may have elevated risk for diabetes complications; these patients had the lowest mean catalase and HDL, as well as the highest glucose, haemoglobin A1c, cholesterol and ApoB.
