OBJECTIVE Published studies on the prevalence of celiac disease in type 1 diabetes mellitus from the Arab World are scant. We aim to report the prevalence of celiac disease in Omani children with type 1 diabetes mellitus. METHODS Children with type 1 diabetes mellitus were prospectively screened for celiac disease, at Sultan Qaboos University Hospital, Muscat, Oman over a period of one year (...

Coeliac disease is a gluten-sensitive enteropathy that develops in genetically susceptible individuals. The disease exhibits many features of an autoimmune disorder. These include the production of highly specific anti-endomysial autoantibodies directed against the enzyme tissue transglutaminase. It is well accepted that wheat-, barley- and rye-based foods should be excluded in the gluten-free ...

Celiac disease is a chronic illness of the small bowel caused by gliadin intolerance in genetically predisposed subjects. The aim of this study was to investigate serum levels of IgA and IgG antigliadin antibodies, IgA antiendomysial antibodies, and IgA anti-tissue transglutaminase antibodies in 169 patients with autoimmune thyroid diseases, i.e. chronic thyroiditis and Graves' disease. Antiend...

Background: Celiac disease (CD) is a common disease caused by autoimmunity to the gluten protein. Although some studies have shown an association between infertility and abortion with CD, there are many risk factors that may influence this relationship that should be addressed in the researches. Therefore, we designed this study to evaluate this association with respect to these confounding fac...

BACKGROUND Serologic methods have been used widely to test for celiac disease and have gained importance in diagnostic definition and in new epidemiologic findings. However, there is no standardization, and there are no reference protocols and materials. METHODS The European working group on Serological Screening for Celiac Disease has defined robust noncommercial test protocols for immunoglo...

Two human erythroleukemia cell lines, HEL and K562, express transglutaminase activity. The enzyme was identified as a tissue transglutaminase following chromatographic purification. All-trans-retinoic acid (10 microM) stimulated differentiation in HEL cells as judged by a 4-fold increase in hemoglobin content and a reduction in cell proliferation. The transglutaminase activity increased 9-fold....

Transglutaminase-2 (TG2) is the most highly and ubiquitously expressed member of transglutaminase enzyme family primarily involved in protein cross-linking. TG2 has been implicated development progression numerous cancers, with a direct role multiple cellular processes pathways linked to apoptosis, chemoresistance, epithelial-mesenchymal transition, stem cell phenotype. The tumour microenvironm...

Transglutaminases are a family of eight currently known calcium-dependent enzymes that catalyze the cross-linking or deamidation of proteins. They are involved in important biological processes such as wound healing, tissue repair, fibrogenesis, apoptosis, inflammation and cell-cycle control. Therefore, they play important roles in the pathomechanisms of autoimmune, inflammatory and degenerativ...
