Plasminogen activator inhibitor-1 (PAI-1) is the primary inhibitor of tissue-type plasminogen activator (tPA) and urokinase-type plasminogen activator (uPA), and functionally serves to suppress tissue and plasma fibrinolysis.

PAI-1 is a member of the serpin family of proteins and exists in multiple conformations of which a minor component, the “active” form, exhibits inhibitory effects against tPA and uPA.

PAI-1 is an endogenous inhibitor of urokinase-type plasminogen activator (uPA), and its expression is regulated by a number of intrinsic factors (e.g., cytokines and growth factors) and extrinsic factors (e.g., cellular stress).

PAI-1 seems to play a pivotal role in tumor growth and may represent a potential therapeutic target for bladder cancer.
