Usage

Uses

Used in Pharmaceutical Industry:
Plasminogen is used as a therapeutic agent for the treatment of various conditions, including blood clots and thrombotic disorders. It is activated by certain activators, such as tissue plasminogen activator (tPA), to its active form, plasmin, which helps in breaking down blood clots and restoring blood flow.
Used in Research and Development:
Plasminogen is used as a subject of study in research and development to understand its conversion into plasmin and its role in the fibrinolytic system. This knowledge aids in the development of new drugs and therapies targeting blood clotting and related disorders.
Used in Diagnostic Applications:
Plasminogen is used as a biomarker in diagnostic tests to assess the risk of blood clot formation and monitor the effectiveness of treatments for thrombotic disorders. Abnormal levels of plasminogen may indicate an increased risk of clot formation or a response to treatment.

Biochem/physiol Actions

Plasminogen is the inactive precursor of the protease plasmin. Plasminogen is activated by the action of either tissue plasminogen activator (tPA), which primarily activates the fibrinolytic (thrombolytic) activity of plasmin, or urokinase plasminogen activator (uPA), which is associated with extracellular matrix remodeling and cell migration. Plasmin cleaves fibrin/fibrinogen and blood coagulation factors V/Va and VIII/VIIIa. It activates matrix metalloproteinases by cleaving the inactive proenzymes. It is also involved in the activation of some growth factors, such as vascular endothelial growth factor (VEGF) and transforming growth factor β (TGF-β).
