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 ...

Staphylococcus aureus proteins Sbi and Efb recruit human plasmin to degrade complement C3 and C3b. [PDF]
Upon host infection, the human pathogenic microbe Staphylococcus aureus (S. aureus) immediately faces innate immune reactions such as the activated complement system. Here, a novel innate immune evasion strategy of S. aureus is described.

KAT7‐acetylated and cytoplasm‐translocated G‐protein GαS enhances IL‐6 effect and drives HCC progenitor cell progression. Abstract Background and Aims Hepatocarcinogenesis goes through HCC progenitor cells (HcPCs) to fully established HCC, and the mechanisms driving the development of HcPCs are still largely unknown.

Urokinase‐Type Plasminogen Activator, an Endogenous Antibiotic [PDF]
Urokinase-type plasminogen activator (uPA) is a serine protease that not only displays fibrinolytic function but also modulates innate and adaptive immune responses. In the present study, we assessed whether uPA acts as an endogenous antibiotic. It has been demonstrated that uPA inhibits growth of Staphylococcus aureus both in vivo and in vitro ...

Role of multidomain structure of urokinase in regulation of growth and remodeling of vessels [PDF]
Urokinase type plasminogen activator, or urokinase (uPA), is a multifunctional protein which plays special regulatory role in the vascular wall and can actuate the proteolytic and signal cascades.

Characterization of the murine plasminogen/urokinase‐type plasminogen‐activator system [PDF]
The murine plasminogen/urokinase‐type plasminogen‐activator (u‐PA) system was studied using purified proteins, plasma and endothelioma cells. Recombinant murine u‐PA was obtained as a single‐chain molecule of 45 kDa which was converted to two‐chain u‐PA with plasmin by cleavage of the Lys159‐Ile1 60 peptide bond.

Leukocyte- and endothelial-derived microparticles: a circulating source for fibrinolysis
Background We recently assigned a new fibrinolytic function to cell-derived microparticles in vitro. In this study we explored the relevance of this novel property of microparticles to the in vivo situation.Design and Methods Circulating microparticles ...

Gelsolin induces colorectal tumor cell invasion via modulation of the urokinase-type plasminogen activator cascade [PDF]
Gelsolin is a cytoskeletal protein which participates in actin filament dynamics and promotes cell motility and plasticity. Although initially regarded as a tumor suppressor, gelsolin expression in certain tumors correlates with poor prognosis and ...

The role of the host—Neutrophil biology
Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...
