BACKGROUND Alpha-1 antitrypsin (A1AT) deficiency, caused by the Z allele (p.E342K) and S allele (p.E264V) in the SERPINA1 gene, can induce liver and pulmonary disease. Different mechanisms appear to be responsible for the pathogenesis of these divergent disease expressions. The c.-1973T >C polymorphism located in the SERPINA1 promoter region is found more frequent in A1AT deficiency patients wi...

Western blot of synovial fluid has been widely used for osteoarthritis (OA) research and diagnosis, but there is no ideal loading control for this purpose. Although β-actin is extensively used as loading control in western blot, it is not suitable for synovial fluid because it is not required in synovial fluid as a cytoskeletal protein. A good loading control for synovial fluid in OA studies sh...

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...

Alpha-1antitrypsin (A1AT) deficiency, an inherited disorder, has been shown to be the cause of lung diseases such as emphysema and chronic obstructive pulmonary disease. One of the treatment strategies to provide appropriate and adequate concentrations of A1AT in the lungsis the application of nanoparticles (NPs) in pulmonary drug delivery. In the current study, biocompatible nanohydrogels were...

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...

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...
