Alpha1-antitrypsin (AAT) deficiency is characterized by the accumulation of the misfolded mutant, Z form of alpha1-antitrypsin (PiZ) inside the lumen of the hepatic endoplasmic reticulum (ER). Both human patients and PiZ transgenic mice have similar symptoms of hepatic failure culminating in cirrhosis and hepatocellular carcinoma. The involvement of(More)
Myocardial infarction (MI) causes an extensive loss of heart muscle cells and leads to congestive heart disease (CAD), the leading cause of mortality and morbidity worldwide. Mesenchymal stromal cell- (MSC-) based cell therapy is a promising option to replace invasive interventions. However the optimal cell type providing significant cardiac regeneration(More)
Cellular adhesion to the underlying substratum is regulated through numerous signaling pathways. It has been suggested that insulin receptor substrate 1 (IRS-1) is involved in some of these pathways, via association with and activation of transmembrane integrins. Calreticulin, as an important endoplasmic reticulum-resident, calcium-binding protein with a(More)
