OBJECTIVES α-1-Antitrypsin (A1AT) deficiency is a common genetic disease with an unpredictable and highly variable course. The Childhood Liver Disease Research and Education Network is a National Institutes of Health, multicenter, longitudinal consortium studying pediatric liver diseases, with the objective of prospectively defining natural history and identifying disease modifiers. METHODS L...
Mineral dust exposure can result in emphysema and chronic airflow obstruction. We postulated that dust-induced emphysema has a pathogenesis similar to that in cigarette smoke-induced emphysema, namely, excess release of proteolytic enzymes from dust-evoked inflammatory cells, and inactivation of alpha-1-antitrypsin (A1AT) by dust-catalyzed formation of oxidants. To test this theory we examined ...
Alpha-1 antitrypsin (A1AT or AAT) is a serine protease inhibitor (PI) which, when present at low levels, can cause chronic obstructive pulmonary disease (COPD) and liver disease in both children and adults. Several mutations within the SERPINA1 gene have been found to cause this deficiency. The most common variants are PI*Z and PI*S, each caused by a single nucleotide polymorphism (SNP). We des...
A1AT deficiency has a complex pathophysiology, is highly variable in clinical course, and is under diagnosed. The association with chronic lung disease was first described by Eriksson and Laurell in 1963, and later, Sharp and colleagues recognized A1AT deficiency as a cause of liver disease. In 2013 an international meeting was held to review the intervening 50 years of basic and clinical scien...
Protein misfolding is implicated in many diseases, including the serpinopathies. For the canonical inhibitory serpin α1-antitrypsin (A1AT), mutations can result in protein deficiencies leading to lung disease and polymerization prone mutants can accumulate in hepatocytes leading to liver disease. Using all-atom simulations based on the recently developed Bias Functional algorithm we elucidate h...
To assess the effects of constitutive hepatitis C virus (HCV) gene expression on liver, transgenic mice carrying the entire HCV open reading frame inserted in the alpha1 antitrypsin (A1AT) gene were generated. Expression of A1AT/HCV mRNA was found to be mainly limited to perivascular areas of the liver as indicated by in situ hybridization analysis. HCV core protein was detected in Western blot...
background alpha-1 antitrypsin deficiency is a genetic disease which affects both lung and liver. this disease is a recognized factor for chronic obstructive pulmonary disease (copd). however its importance as the cause of copd in a country such as iran is unclear. objectives this study was conducted to find out the role of α-1 antitrypsin deficiency as a cause of copd in iranian patients. mate...
BACKGROUND In this study, we further investigated the association of two biomarkers, CCL18 and A1AT, with bladder cancer (BCa) and evaluated the influence of potentially confounding factors in an experimental model. METHODS In a cohort of 308 subjects (102 with BCa), urinary concentrations of CCL18 and A1AT were assessed by enzyme-linked immunosorbent assay (ELISA). In an experimental model, ...
We sought to identify serological markers capable of diagnosing preeclampsia (PE). We performed serum peptide analysis (liquid chromatography mass spectrometry) of 62 unique samples from 31 PE patients and 31 healthy pregnant controls, with two-thirds used as a training set and the other third as a testing set. Differential serum peptide profiling identified 52 significant serum peptides, and a...
