ProteomicsCELA1 and AAT deficient murine model proteome
Chymotrypsin-like elastase 1 (CELA1) is a serine protease that is neutralized by alpha-1 antitrypsin (AAT) and prevents emphysema in a murine antisense oligonucleotide model of AAT-deficient emphysema. We tested the role of CELA1 in emphysema development in this genetic model of AAT-deficiency follo...

ProteomicsCharacterization of a new variant of SERPINA1 Gene Causing Alpha-1 Antitrypsin Deficiency
Alpha 1-Antitrypsin Deficiency (AATD) is a rare genetic disorder caused by mutations in the SERPINA1 gene, which encodes the Alpha 1-Antitrypsin (AAT) protein. Individuals carrying pathogenic SERPINA1 variants are predisposed to lung and liver damage. The most common AATD-associated SERPINA1 alleles...

TranscriptomicsRNA-seq of hepatocytes obtained through step-wise differentiation of hIPSCs from a patient with A1AT deficiency and its point mutation-corrected isogenic hIPSC line. Comparison to primary hepatocytes from a healthy donor and an A1AT-deficient patient.
A1AT deficiency is an autosomal not recessive disorder caused by mutations in the SERPINA1 gene. Individuals with the Z variant retain polymerised protein in the endoplasmic reticulum of hepatocytes, predisposing them to liver disease. This study primarily aimed to uncover the molecular mechanisms t...

TranscriptomicsTranscription profiling of mouse transgenics (3 mo) inducibly expresssing human alpha1-antitrypsin in the liver
In the classical form of α1antitrypsin deficiency a mutant protein accumulates in a polymerized form in the ER of liver cells causing liver damage and carcinogenesis by a gain-of-toxic function mechanism. Recent studies have indicated that the accumulation of mutant α1antitrypsin Z in the ER spec...

ProteomicsIn alpha-1 antitrypsin deficiency, loss of the mechanistic target of rapamycin complex 1 (mTORC1) causes a lethal hepatic zonation defect
Alpha1-antitrypsin (AAT) mutations lead to the retention of the otherwise secreted protein thereby giving rise to AAT deficiency (AATD). AATD-related liver disease (AATD-LD) arises due to the proteotoxic stress and is the second leading cause of mortality in AATD with no approved pharmacologic treat...
