The chicken urokinase-type plasminogen activator gene

Fibrinolysis, 1989
The chicken urokinase-type plasminogen activator (uPA) cDNA and gene have been isolated and the complete nucleotide sequence of each established. cDNA sequence and Northern blot RNA analysis indicate that the chicken uPA mRNA is approximately 2500 nucleotides in size and contains a large 3'-noncoding region (998 nucleotides).

Origin and diversification of the plasminogen activation system among chordates

BMC Evolutionary Biology, 2019
Background The plasminogen (PLG) activation system is composed by a series of serine proteases, inhibitors and several binding proteins, which together control the temporal and spatial generation of the active serine protease plasmin. As this proteolytic

Amiloride selectively inhibits the urokinase‐type plasminogen activator

FEBS Letters, 1987
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 ...

Urokinase-type plasminogen activator in carcinomatous pleural fluid [PDF]

European Respiratory Journal, 1997
Urokinase-type plasminogen activator (u-PA) is known to be secreted by malignant cells during proliferation and migration, and is associated with tumour cell invasion and metastasis. This study was undertaken to evaluate whether u-PA is significantly increased in carcinomatous pleural fluids compared to those due to other aetiologies, and to identify ...

QSAR modelling to predict structural features of certain sulfonamide as Urokinase-type Plasminogen Activator inhibitors

Chemical Physics Impact
The serine hydrolase family includes serine proteases. It is essential for hydrolyzing protein peptide bonds and breaking them. The urokinase-type plasminogen activator (uPA) selectively binds to the uPAR on numerous cell types, including cancer cells ...

Overexpression of the urokinase receptor splice variant uPAR-del4/5 in breast cancer cells affects cell adhesion and invasion in a dose-dependent manner and modulates transcription of tumor-associated genes [PDF]

, 2012
mRNA levels of the urokinase receptor splice variant uPAR-del4/5 are associated with prognosis in breast cancer. Its overexpression in cancer cells affects tumor biologically relevant processes.

Soluble urokinase-type plasminogen activator receptor and urokinase-type plasminogen activator receptor contribute to chemoresistance in leukemia

Oncology Letters, 2017
The soluble urokinase-type plasminogen activator receptor (suPAR) and the urokinase-type plasminogen activator receptor (uPAR) have been proposed as useful biomarkers of tumor progression. Recently, suPAR was associated with chemoresistance in lung cancer. However, its clinical significance in leukemia has not previously been investigated.

Thrombolytic proteins profiling: High‐throughput activity, selectivity, and resistance assays

FEBS Open Bio, EarlyView.
We present optimized biochemical protocols for evaluating thrombolytic proteins, enabling rapid and robust screening of enzymatic activity, inhibition resistance, and fibrin affinity, stimulation, and selectivity. The outcome translates to key clinical indicators such as biological half‐life and bleeding risk. These assays streamline the development of
