Group B Streptococcus hijacks the host plasminogen system to promote brain endothelial cell invasion. [PDF]

PLoS ONE, 2013
Group B Streptococcus (GBS) is the leading cause of meningitis in neonates. We have previously shown that plasminogen, once recruited to the GBS cell surface and converted into plasmin by host-derived activators, leads to an enhancement of bacterial ...

Decoding the role of angiopoietin-like protein 4/8 complex–mediated plasmin generation in the regulation of LPL activity

Journal of Lipid Research, 2023
After feeding, adipose tissue lipoprotein lipase (LPL) activity should be maximized, therefore the potent LPL-inhibitory activity of angiopoietin-like protein 4 (ANGPTL4) must be blocked by ANGPTL8 through formation of ANGPTL4/8 complexes.

Chemical Synthesis and Functional Screening of an 800 000‐Member Library Using a Peptide‐Pairing Strategy

Angewandte Chemie, EarlyView.
Chemical peptide synthesis allows the generation of structurally highly diverse compounds suited for ligand development, but current methods in parallel peptide synthesis limit the achievable library size to a few thousand. A strategy is presented based on combinatorial pairing of short peptides via disulfide linkage that enables the generation and ...

Endoproteolysis of cellular prion protein by plasmin hinders propagation of prions

Frontiers in Molecular Neuroscience, 2022
Many questions surround the underlying mechanism for the differential metabolic processing observed for the prion protein (PrP) in healthy and prion-infected mammals.

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.

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.

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?

Effect of dsRNA on Mesangial Cell Synthesis of Plasminogen Activator Inhibitor Type 1 and Tissue Plasminogen Activator [PDF]

, 2009
Background/Aims: Viral infections are a major problem worldwide and many of them are complicated by virally induced glomerulonephritides. Progression of kidney disease to renal failure is mainly attributed to the development of renal fibrosis ...
