Ichthyosiform dermatosis is a term referred to a group of disorders that have as their basis a disorder of keratinization (1). These conditions which are present at birth result in a generalized dry, scaly skin without any inflammation. There are several types of ichthyosis based on their clinical presentation and mode of inheritance. The most common types are: ichthyosis vulgaris, X-linked recessive ichthyosis, epidermolytic hyperkeratosis (bullous), lamellar ichthyosis and non-bullous ichthyosiform erythroderma...

BACKGROUND & AIMS: Little is known about the prevalence and burden of undiagnosed celiac disease in individuals younger than 50 years old. We determined the prevalence and morbidity of undiagnosed celiac disease in individuals younger than 50 years in a community. METHODS: We tested sera from 31,255 residents of Olmsted County, Minnesota (younger than 50 years old) without a prior diagnosis of celiac disease assay using an assay for immunoglobulin A (IgA) against tissue transglutaminase (tTG); in subjects with positive test results, celiac disease was confirmed using an assay for endomysial IgA...

Astrocytes play numerous complex roles that support and facilitate the function of neurons. Further, when there is an injury to the central nervous system (CNS) they can both facilitate or ameliorate functional recovery depending on the location and severity of the injury. When a CNS injury is relatively severe a glial scar is formed, which is primarily composed of astrocytes. The glial scar can be both beneficial, by limiting inflammation, and detrimental, by preventing neuronal projections, to functional recovery...

Celiac disease is usually diagnosed by demonstrating gluten enteropathy in small bowel biopsy. Celiac specific antibodies are used as an initial screening test. The goal of this study is to test the relationship of the anti-tTG titer and severity of histological changes in Jordanian children with celiac disease. Method. The medical records of 81 children who had elevated anti-tTG titer and had duodenal biopsies available were retrospectively reviewed. Result. Assessing the association of anti-tTG titer with duodenal histopathological changes, 94% of those with high anti-tTG titer (≥180 U/mL) had histological evidence of celiac disease...

Deposition of amyloid-beta (Aβ) peptides has been shown to induce the release of inflammatory factors by activated microglia and brain infiltrating monocytes/macrophages. Interestingly, the enzyme transglutaminase 2 (TG2) has been shown to play a key role in neuroinflammation and regulation of transcription factors involved in immunomodulation. In this study, we aimed to better elucidate the mechanisms underlying TG2 involvement in the pro-inflammatory signaling pathway activated by fibrillar Aβ1-42 in THP-1 monocytes...

BACKGROUND & AIMS: Celiac disease is detected using serology and endoscopy analyses. We used multiple statistical analyses of a geographically isolated population in the United States to determine whether a single serum screening can identify individuals with celiac disease. METHODS: We performed a retrospective study of 3555 pediatric patients (18 years old or younger) in the intermountain West region of the United States from January 1, 2008 through September 30, 2013...

BACKGROUND: Alopecia areata (AA) is a noncicatricial (nonscarring) alopecia. The association between AA and celiac disease (CD) is debatable. Several studies declare the relationship between AA and CD as measurement of celiac autoantibodies (anti-gliadin IgA and anti-gliadin IgG), but a few studies consider anti-tissue transglutaminase IgA. The aim of this study was to evaluate the frequency distribution of celiac autoantibodies (all of them) in patients with AA compared with controls...

Transglutaminase 2 (TG2) is a ubiquitously expressed enzyme that catalyzes crosslinking, polyamination or deamidation of glutamine residues in proteins. It has been reported that TG2 is involved in the pathogenesis of various inflammatory diseases including celiac disease, pulmonary fibrosis, cystic fibrosis, multiple sclerosis and sepsis. Recently, using a mouse model of bleomycin-induced lung fibrosis, we showed that TG2 is required to trigger inflammation via the induction of T helper type 17 (Th17) cell differentiation in response to tissue damage...

BACKGROUND: Immunoglobulin A (IgA) antibodies to tissue transglutaminase (tTG) are the serologic test of choice for diagnosing celiac disease (CD). Our aim was to determine if elevated IgA anti-tTG were associated with increased mortality risk. METHODS: Stored serum samples of National Health and Nutrition Examination Survey (NHANES) III (1988-1992) were available for 6032 individuals aged 50 years old or above, which were screened for IgA anti-tTG, and if positive, for IgA endomysial antibodies...

Utilizing a variety of flow cytometric methods evidence was obtained indicating that a combination of the glucose analog 2-deoxy-D-glucose (2-dG) and the plant alkaloid berberine (BRB) produces synergistic effect in the induction of apoptosis in human lymphoblastoid TK6 cells. The synergistic effect is seen at concentrations of the drugs at which each of them alone shows no cytotoxicity at all. The data suggest that the combination of these drugs, which are known in terms of their overall toxicity, side effects and pharmacokinetics may be considered for further studies as chemopreventive and cancer treatment modalities...

BACKGROUND: Transglutaminases (TGase), which are synthesized as a zymogen (pro-TGase) in Streptomyces sp., are important enzymes in the food industry. Because this pro-peptide is essential for the correct folding of Streptomyces TGase, TGase is usually expressed in an inactive pro-TGase form, which is then converted to active TGase by the addition of activating proteases in vitro. In this study, Streptomyces hygroscopicus TGase was actively produced by Streptomyces lividans through promoter engineering and codon optimization...

Resistance to chemotherapy is a hallmark of pancreatic ductal adenocarcinoma (PDA) and has been partly attributed to the dense desmoplastic stroma, which forms a protective niche for cancer cells. Tissue transglutaminase (TG2), a Ca(2+)-dependent enzyme, is secreted by PDA cells and cross-links proteins in the tumor microenvironment (TME) through acyl-transfer between glutamine and lysine residues, promoting PDA growth. The objective of the current study was to determine whether secreted TG2 by PDA cells alters the response of pancreatic tumors to gemcitabine...

Paroxysmal gluten-sensitive dyskinesia (previously termed canine epileptoid cramping syndrome) is a condition of Border terriers in which the leading manifestation is neurological. The authors describe a case they believe to represent the first report of a Border terrier with a combination of neurological signs, atopy, positive serological results for anti-transglutaminase 2 (TG2 IgA) and anti-gliadin (AGA IgG) antibodies, and signs suggestive of gastrointestinal disease with pathological changes in the gastrointestinal tract-seemingly responsive to a gluten-free diet...

Transglutaminase 2 (TG2) is a Ca(2+)-dependent cross-linking enzyme involved in the pathogenesis of CD. We have previously characterized a panel of anti-TG2 mAbs generated from gut plasma cells of celiac patients and identified four epitopes (epitopes 1-4) located in the N-terminal part of TG2. Binding of the mAbs induced allosteric changes in TG2. Thus, we aimed to determine whether these mAbs could influence enzymatic activity through modulation of TG2 susceptibility to oxidative inactivation and Ca(2+) affinity...

Hepatitis B virus (HBV) infection is a major risk factor which can lead to development of hepatocellular carcinoma (HCC). Tissue transglutaminase-2 (TG2) has been shown to be critical for cancer progression. However, how TG2 promotes the progression of HBV-related HCC remains unknown. In this study, we aimed to explore the expression and function of TG2 on HBV-related HCC progression. The expression levels of TG2 were examined in a series of HBV-related HCC tissues and a panel of HCC cell lines. The effects of TG2 knockdown on the proliferation and migration of HBV-related cells were determined...

Transglutaminase 2 (TG2) expression is required for epidermal squamous cell carcinoma cancer stem cell survival. However, the molecular signaling mechanisms triggered by TG2 that mediate this survival action are not well understood. Here we show that TG2 is constitutively expressed in ECS cells where it interacts with α6/β4 integrin to stimulate FAK and Src signaling, leading to phosphoinositide 3 kinase (PI3K) activation of phosphoinositide dependent kinase 1 (PDK1). PDK1 inhibits Hippo signaling, leading to enhanced nuclear accumulation of YAP1, which interacted with and stabilized ΔNp63α to enhance ECS cell spheroid formation, invasion, and migration...

OBJECTIVES: Curcumin, a naturally occurring compound derived from turmeric (Curcuma longa) has long been suggested to have strong therapeutic or preventive potential against human diseases because of its antioxidative, anticancerous, and anti-inflammatory effects. Curcumin is known to exert anti-inflammatory effects by interrupting NF-κB signaling at multiple levels. Many observations indicate that curcumin shows its valuable potential by inhibiting the activity of I-κB kinase. Transglutaminase 2 (TG2) expression is increased in inflammatory diseases...

Tissue transglutaminase (tTG) belongs to the multigene transglutaminase family of Ca(2+)-dependent protein cross-linking enzymes. There is a strong evidence that tTG is involved in pathology, such as neurodegenerative diseases, cancer, and celiac disease. To study physiopathological implication of tTG, a sandwich immunoassay has been developed with a new monoclonal antibody for the capture and polyclonal antibody both generated in house. Using this ready to use assay, the tTG protein level can be measured in human tissue homogenates and cells extracts easily in about 4 h...
