General description
Plasminogen activator inhibitor 1 (PAI-1) or serine protease inhibitor E1 (SERPINE1) gene is mapped to human chromosome 7q22.1. PAI-1 is produced in hepatocytes, endothelial cells, smooth muscle cells, megakaryocytes, and adipocytes.
Application
Plasminogen activator inhibitor 1 (PAI-1) human has been used:
- as an inhibitor of pro-brain-derived neurotrophic factor (proBDNF) in radioimmunoprecipitation assay (RIPA) in peripheral blood and lymphocytes
- to block plasmin activation in mice infected with C. albicans hyphae
- to test its effect on neurite growth in neurons
Biochem/physiol Actions
Plasminogen Activator Inhibitor 1 (PAI-1) protein belongs to the Serpin superfamily of serine protease inhibitors. It is the principal inhibitor of tissue plasminogen activator (tPA) and urokinase (uPA), the activators of plasminogen and therefore inhibits the fibrinolysis process. PAI is involved in extracellular matrix remodeling and has been implicated in processes like angiogenesis, chemotaxis, ovulation, and embryogenesis. PAI-1 is present in increased levels in various disease states such as a number of cancer forms, obesity and the metabolic syndrome.
Plasminogen activator inhibitor–1 (PAI -1) participates in mediating cellular senescence. It is upregulated during injury along with other tissue repair transcriptomes. Elevated levels of PAI-1 is regarded as one of the risks associated with myocardial infarction (MI).
Unit Definition
