BACKGROUND α-1-Antitrypsin (A1AT) deficiency results from a genetic disorder at 2 common loci. Diagnosis requires quantification of A1AT and subsequent identification of the specific variant. The current algorithm of laboratory testing for the diagnosis of A1AT deficiency uses a combination of quantification (nephelometry), genotyping, and/or phenotyping. We developed a multiple reaction monito...
The latent variable "δ" (for "dementia") uniquely explains dementia severity. Depressive symptoms are independent predictors of δ. We explored 115 serum proteins as potential causal mediators of the effect of depressive symptoms on δ in a large, ethnically diverse, longitudinal cohort. All models were adjusted for age, apolipoprotein E, education, ethnicity, gender, hemoglobin A1c, and homocyst...
in this study, in order to facilitate and accelerate the production of eukaryotic protein alpha 1-antitrypsin (aat) with correct post-translational modifications, a protein production system based on the transduction of cho and cos-7 cells using lentiviral vectors was developed. human aat cdna was cloned into a replication-defective lentiviral vector. the transgene aat-jred chimer was transferr...
inducing a proteolytic burden in the lung microenvironment. Under normal circumstances, A1AT and other antiproteases neutralize this threat posed by neutrophils. However, in A1AT deficiency, defenses are perturbed, leading to elastic degradation on lung tissue resulting in emphysema. While most COPD patients do not have A1AT, this genetic syndrome serves as a useful human model of how disturban...
The angiopoietin-like protein 4 (angptl4, also known as peroxisome proliferator-activated receptor [PPAR]γ-induced angiopoietin-related protein) is a multifunctional protein associated with acute-phase response. The mechanisms accounting for the increase in angptl4 expression are largely unknown. This study shows that human α1-antitrypsin (A1AT) upregulates expression and release of angplt4 in ...
human alpha 1-antitrypsin (aat) cdna was obtained from hepg2 cell lines. after pcr and construction of expression vector ppiczα-aat, human aat was expressed in the yeast pichia pastoris (p.pastoris) in a secretary manner and under the control of inducible alcohol oxidase 1 (aox1) promoter. the amount of aat protein in medium was measured as 60 mg/l 72 hr after induction with methanol. results i...
objective(s):psoriasis is an autoimmune disease that appears on the skin. although psoriasis is clinically and histologically well characterized, its pathogenesis is unknown in detail. the aims of this study were to evaluate the proteome of psoriatic patients' sera and to compare them with those of normal healthy human to find valuable biomarkers. materials and methods: in a case-control s...
CONTEXT Under normal physiological conditions, leptin regulates body weight by creating a balance between food intake and energy expenditure. However, in obesity, serum leptin levels increase and become defective to retain energy balance. EVIDENCE ACQUISITION Elevated serum leptin levels are regarded as an established marker of obesity. It is also reported that obese asthmatic patients have m...
