Tissue transglutaminase functions as a protein crosslinking enzyme and an integrin-binding adhesion co-receptor for fibronectin on the cell surface. These activities of transglutaminase and the involvement of this protein in cell-matrix adhesion, integrin-mediated signaling, cell migration and matrix organization suggest a precise and efficient control of its cell-surface expression. We report ...

Introduction/Objective Celiac disease (CD) is the result of a polygenic predisposition and gluten-containing diet. The aim this study was to determine prevalence clinical forms CD in siblings children with verified disease. Methods included 83 siblings, aged 1.5-27 (11.77 ? 6.2) years, from 64 CB diagnosed according ESPGHAN criteria (1990/2012). In addition detailed history examination, serum l...

BACKGROUND Celiac disease (CD) is a common genetically transmitted immune mediated disease. METHOD Seventy three type 1 DM patients attending the Diabetes, Metabolic and Endocrinology outpatient clinic were recruited in the study. Thorough history taking and medical examination were done. They were screened for the prevalence of celiac disease by ELISA for coeliac disease antibodies against t...

BACKGROUND/AIMS The objective of this study was to determine the prevalence of Celiac disease in Turkish children with type 1 Diabetes Mellitus and their non-diabetic first-degree relatives. METHODS Forty-eight children with type 1 Diabetes Mellitus (18 males, 30 females; age range: 3.5 to 23 years; mean age: 12.09 +/- 4.78 years), 29 non-diabetic siblings, 40 non-diabetic parents, and 103 he...

BACKGROUND Celiac disease is an immune-mediated inflammation of the small intestine caused by sensitivity to dietary gluten in genetically sensitive individuals. OBJECTIVES In this study, we aimed to evaluate the predictive value of tissue transglutaminase (tTG) antibodies for the diagnosis of celiac disease in a pediatric population in order to determine if duodenal biopsy can be avoided. ...

Phospholipases A2 are enzymes that liberate membrane-bound lipids in a tissue and cell-specific fashion. Group V secretory phospholipase A2 is necessary for the development of M2 macrophages and their effector functions in a mouse model of the T-helper-2 allergic airway inflammation. However, the function of group V phospholipase A2 in human M2 activation and T-helper-2 inflammation is ill-defi...

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 4 (TG4) is a member of the enzyme family that catalyzes the calcium-dependent post-translational modification of proteins via cross-linking, polyamination, or deamidation. TG4 exhibits prostate-specific expression pattern and plays a crucial role in the formation of the copulatory plug in rodents. However, the physiological function(s) of human TG4 remains speculative. Human TG...
