Separation and characterization of nonphosphorylated and serine-phosphorylated urokinase. Catalytic properties and sensitivity to plasminogen activator inhibitor type 1. [PDF]
Urokinase synthesized by human A431 epidermoid carcinoma cells is phosphorylated on serine (Mastronicola, M. R., Stoppelli, M. P., Migliaccio, A., Auricchio, F., and Blasi, F. (1990) FEBS Lett. 266, 109-114).

Multiparity upregulates placental plasminogen and urokinase‐type plasminogen activator
ProblemMultiparity increased the number of trophoblast cells in decidua of both low and high fetal loss mouse models. However, they differ in fetal survival rate and maternal thymocyte subpopulations, suggesting that trophoblast invasiveness is not equivalent.

The urokinase-type plasminogen activator receptor (uPAR) is a GPI-anchored cell membrane receptor that focuses urokinase (uPA) proteolytic activity on the cell surface.

Retinoic Acid Upregulates the Plasminogen Activator System in Human Epidermal Keratinocytes [PDF]
The activation of the proteolytic plasminogen activator system is important for the re-epithelialization of skin wounds. Keratinocytes synthesize and secrete the urokinase-type plasminogen activator, which binds to its specific receptor on keratinocytes.

Proenzyme to urokinase‐type plasminogen activator in the mouse in vivo [PDF]
We have investigated whether urokinase‐type plasminogen activator (u‐PA) is present in the mouse in vivo as the proenzyme or as the active enzyme. u‐PA in extracts of various murine tissues was of a one‐polypeptide chain form with an electrophoretic mobility indistinguishable from purified proenzyme (pro‐u‐PA), as demonstrated by SDS‐polyacrylamide gel

UVB Increases Urokinase-Type Plasminogen Activator Receptor (uPAR) Expression1 [PDF]
Keratinocytes synthesize and secrete urokinase-type plasminogen activator, which binds to its specific receptor on keratinocytes. When bound to urokinase-type plasminogen activator receptor, urokinase-type plasminogen activator proteolytically converts ...

Axonal injury is a common cause of neurological dysfunction. Unfortunately, in contrast to axons from the peripheral nervous system, the limited capacity of regeneration of central nervous system (CNS) axons is a major obstacle for functional recovery in

Transcriptional regulation of the urokinase receptor (u-PAR) - A central molecule of invasion and metastasis [PDF]
The phenomenon of tumor-associated proteolysis has been acknowledged as a decisive step in the progression of cancer. This short review focuses on the urokinase receptor (u-PAR), a central molecule involved in tumor-associated invasion and metastasis ...

Nuclear translocation of urokinase-type plasminogen activator
AbstractUrokinase-type plasminogen activator (uPA) participates in diverse (patho)physiological processes through intracellular signaling events that affect cell adhesion, migration, and proliferation, although the mechanisms by which these occur are only partially understood. Here we report that upon cell binding and internalization, single-chain uPA (

Background. Urokinase plasminogen activator (uPA) and plasminogen activator inhibitor type-1 (PAI-1) play a key role in tumour invasion and metastasis. High levels of both proteolytic enzymes are associated with poor prognosis in breast cancer patients ...
