Plasminogen activator inhibitor-I and tumour growth, invasion, and metastasis.
In recent decades, evidence has been accumulating showing the important role of urokinase-type plasminogen activator (uPA) in growth, invasion, and metastasis of malignant tumours. The evidence comes from results with animal tumour models and from the observation that a high level of uPA in human tumours is associated with a poor patient prognosis. It therefore initially came as a surprise that...
متن کاملOptimizing refolding condition for recombinant tissue plasminogen activator
Low molecular size additives such as L-arginine and the redox compounds have been used both in the culturemedium and in vitro refolding to increase recombinant proteins production. Additives increase proteinrefolding and yield of active proteins by suppressing aggregate formation or enhancing refolding process.In this work, a comparative study was performed on refolding of rec...
متن کاملPlasminogen activator/plasminogen activator inhibitors in ovarian physiology.
The target extracellular matrix (ECM) degradation generated by plasminogen activator (PA) and regulated by plasminogen activator inhibitor (PAI) is an event that affects a wide variety of physiological and pathological processes in the ovary. Studies carried out over the past 25 years in a number of laboratories have elucidated some of the biochemical events related to the function and regulati...
متن کاملExtravascular fibrin, plasminogen activator, plasminogen activator inhibitors, and airway hyperresponsiveness.
Mechanisms underlying airway hyperresponsiveness are not yet fully elucidated. One of the manifestations of airway inflammation is leakage of diverse plasma proteins into the airway lumen. They include fibrinogen and thrombin. Thrombin cleaves fibrinogen to form fibrin, a major component of thrombi. Fibrin inactivates surfactant. Surfactant on the airway surface maintains airway patency by lowe...
متن کاملPlasminogen Activator in Rabbits
Tissue type plasminogen activator (t-PA) is an effective thrombolytic agent in experimental animals. The duration of the thrombolytic effect of infused t-PA is unknown. We compared the duration of the thrombolytic effect of t-PA with streptokinase by measuring the lysis of 125l-fibrinlabeled thrombi in rabbit jugular veins at different times after a bolus injection of the fibrinolytic agents. T...
