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.

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 ...

Plasminogen Mediates the Pathological Effects of Urokinase-Type Plasminogen Activator Overexpression [PDF]
Increased expression of urokinase-type plasminogen activator (uPA) and its receptor (uPAR) is associated with different pathological conditions. Both uPAR-mediated signaling and plasmin-catalyzed extracellular proteolysis may contribute to pathogenesis.

Background Corneal ulceration leading to perforation is associated with infectious and non-infectious destructive conditions in the cornea. The fibrinolytic (plasminogen/plasmin) system is considered to contribute to tissue remodeling in the wound ...

Amiloride selectively inhibits the urokinase‐type plasminogen activator
The diuretic drug amiloride, an inhibitor of Na+ uptake, competitively inhibits the catalytic activity of the urokinase‐type plasminogen activator (u‐PA), with a K i of 7 × 10−6 M. Generation of plasmin, cleavage of peptide substrates, and interaction of u‐PA with a specific macromolecular proteinase inhibitor are all prevented in the presence of the ...

Dynamic Assembly of the Urokinase-type Plasminogen Activator Signaling Receptor Complex Determines the Mitogenic Activity of Urokinase-type Plasminogen Activator [PDF]
The urokinase-type plasminogen activator (uPA) receptor (uPAR) functions in concert with co-receptors, including integrins, FPR-like receptor-1/lipoxin A4 receptor, and the epidermal growth factor receptor (EGFR), to initiate cell signaling. uPAR co-receptors may be dynamically organized into a multiprotein signaling receptor complex.

Early increases in plasminogen activator activity following partial hepatectomy in humans [PDF]
Background Increases in urokinase-like plasminogen activator (uPA) activity are reported to be amongst the earliest events occurring in remnant liver following partial hepatectomy in rats, and have been proposed as a key component of the regenerative ...
