Numerous studies have provided information indicating the involvement of oxidative stress in the pathophysiology of depressive disorder (DD). The antioxidative system protects against the effects caused by reactive oxygen species (ROS). Catalase (CAT) is one of antioxidative enzymes observed to change their levels in the course of depression. The enzyme decomposes hydrogen peroxide (H(2)O(2)), ...

cataract is multi-factorial eye disease identified by the disturbance of the transparent ocular lens. there is significant evidence suggesting oxidative damage as a major cause of initiation and progression of numerous diseases including cataracts. nad(p)h:quinone oxidoreductase 1 (nqo1; omim: 125860) and catalase (cat, omim: 115500) are antioxidant enzymes that prevent cells from oxidative str...

Background & Objective Catalase (CAT) is an important endogenous antioxidant enzyme that detoxifies H2O2 into water and oxygen, consequently limiting the deleterious effects of reactive oxygen species. It has suggested that CAT-21A/T (rs7943316) OMIM: 115500 gene promoter polymorphism is predominantly associated with different human disorders such as hypertension, cancers, diabetes, nephropathy...

Accumulation of hydrogen peroxide (H(2)O(2)) and low catalase (CAT) activity have been demonstrated in the epidermis of vitiligo patients. We investigated a possible association between the CAT exon 9 (Asp-389) gene and vitiligo susceptibility in the Turkish population. Thirty-four patients with vitiligo and 49 gender, age and ethnic matched controls were enrolled in the study. Genotyping...

This study investigated the influence of gene-gene and gene-environment interactions on the risk of developing asbestosis. The study comprised 262 cases with asbestosis and 265 controls with no asbestos-related disease previously studied for MnSOD, ECSOD, CAT, GSTT1, GSTM1, GSTP1, and iNOS polymorphisms. Data on cumulative asbestos and smoking were available for all subjects. To assess gene-gen...

Catalase (CAT) is a well-studied enzyme that plays an important role in protecting cells against the toxic effects of hydrogen peroxide. In human, it has been implicated in different physiological and pathological conditions. This review summarizes the information available on the function and role of CAT polymorphisms in pathogenesis of various pathophysiological states as well as on the regul...

Shortly after adopting a 6-week-old cat, a veterinarian was bitten on the left index finger. Within 3 weeks, he developed headache, fever, and left axillary lymphadenopathy. Initial blood cultures from the cat and veterinarian were sterile. Repeat cultures from the cat grew Bartonella-like organisms with lophotrichous flagella. Sera from the veterinarian were not reactive against Bartonella hen...

Introduction: Cataract is main cause of reversible blindness and visual impairment. Risk factors include anti-hyperlipidemic drugs such as statin. However, the mechanism statins a risk factor for cataracts not clear. The antioxidant effect statin reported in some studies while other showed negative results. This study was conducted to understand association cataract users with gene abnormalitie...
