Purpose The main aim of this study was investigate the association between the genetic polymorphism of antioxidant enzyme genes: SOD1, CAT and GSHPX1 and the risk of inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis in the Polish population. Methods A total of 445 subjects including 200 patients with IBD and 245 controls were allowed in this study. We determin...

Oxidative stress is known to be one of the major factors involved in the development and progression of cancer. Oxidative stress can occur due to an imbalance between concentrations of reactive oxygen species and antioxidant capacities. Catalase (CAT; OMIM 115500) and superoxide dismutase 1 (SOD1; OMIM 147450) play important roles in the primary defense against oxidative stress. In the present ...

Catalase (CAT), one antioxidant enzyme, may provide resistance against many diseases. Many previous studies reported predictive and prognostic values of CAT C262T polymorphism in cancers, with divergent results. This study aimed to summarize the overall relationships between CAT C262T polymorphism and cancer risk or survival. A total of 27 eligible publications were included in susceptibility a...

INTRODUCTION Bronchial asthma is a complex disease in which genetic factors, environmental factors and oxidative damage are responsible for the initiation and modulation of disease progression. If antioxidant mechanisms fail, reactive oxygen species damage the biomolecules followed by progression of the disease. Catalase is one of the most important endogenous enzymatic antioxidants. In the pre...

The present study evaluated the relationship of genetic variants in both promoter (-262 C/T) and in exonic (389 C/T) regions of the catalase (CAT) gene to CAT activity and risk of systemic lupus erythematosus (SLE) in Suez Canal-area patients. CAT gene polymorphisms were assessed by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). CAT activity was measured by...

Catalase, an endogenous antioxidant enzyme, is responsible for regulating reactive species levels. Several epidemiologic studies have suggested that single nucleotide polymorphism in catalase gene may be associated with many diseases. The genotype of CAT (-21 A/T) point mutation in promoter region of catalase gene was determined by polymerase chain based restriction fragment length polymorphism...

essential hypertension (eh) accounts for 90-95% of hypertension cases. eh, as a progressive cardiovascular syndrome arising from complex and interrelated etiologies, results from combined and interactive effects of genetic and environmental factors. the objective was to investigate the ace i/d and gnb3 c825t polymorphisms and both genotypes combined with seeking gene-gene interactions to furthe...
