Activation of Pro-uPA Is Critical for Initial Escape from the Primary Tumor and Hematogenous Dissemination of Human Carcinoma Cells

Neoplasia: An International Journal for Oncology Research, 2011
Urokinase-type plasminogen activator (uPA) and plasmin have long been implicated in cancer progression. However, the precise contributions of the uPA/plasmin system to specific steps involved in cancer cell dissemination have not been fully established ...

Markers of thrombogenesis and fibrinolysis and their relation to inflammation and endothelial activation in patients with idiopathic pulmonary arterial hypertension.

PLoS ONE, 2013
BackgroundChronic anticoagulation is a standard of care in idiopathic pulmonary arterial hypertension (IPAH). However, hemostatic abnormalities in this disease remain poorly understood.

Exercise, cognition and Alzheimer’s disease: More is not necessarily better [PDF]

, 2005
Regional hypoperfusion, associated with a reduction in cerebral metabolism, is a hallmark of Alzheimer’s disease (AD) and contributes to cognitive decline. Cerebral perfusion and hence cognition can be enhanced by exercise.

Potent, Selective, Allosteric Inhibition of Human Plasmin by Sulfated Non-Saccharide Glycosaminoglycan Mimetics.

Journal of Medicinal Chemistry, 2017
Although plasmin inhibitors could be used in multiple disorders, their use has been restricted to preventing blood loss in hemostatic dysregulation because of poor efficacy and adverse effects of current agents.

Expression of the inhibitory Ly49E receptor is not critically involved in the immune response against cutaneous, pulmonary or liver tumours [PDF]

, 2016
Natural killer (NK) lymphocytes are part of the innate immune system and are important in immune protection against tumourigenesis. NK cells display a broad repertoire of activating and inhibitory cell surface receptors that regulate NK cell activity ...

The half-life of the bone-derived hormone osteocalcin is regulated through O-glycosylation in mice, but not in humans

eLife, 2020
Osteocalcin (OCN) is an osteoblast-derived hormone with pleiotropic physiological functions. Like many peptide hormones, OCN is subjected to post-translational modifications (PTMs) which control its activity.

Enhanced thrombin and plasmin generation profiles in alpha-2-antiplasmin–deficient patients: Data from the Rare Bleeding disorders in the Netherlands study

Research and Practice in Thrombosis and Haemostasis
Background: α2-Antiplasmin (A2AP) deficiency is a rare and often unidentified disorder characterized by increased fibrinolysis and subsequent bleeding. Global hemostasis assays may increase insight into the altered coagulation and fibrinolysis in these ...

A novel mechanism controlling the growth of hemostatic thrombi [PDF]

The Ukrainian Biochemical Journal, 2013
Current knowledge of the mechanisms of blood coagulation does not provide an answer to one pivotal question: why is, in contrast to a pathological thrombus, the growth of normal hemostatic clot after blood vessel injury suddenly terminated?
