Plasmin (Plm), a trypsin-like serine protease, is responsible for fibrinolysis pathway and pathologic events, such as angiogenesis, tumor invasion, metastasis, alters the expression of cytokines. A growing body data indicates that Plm inhibitor potential candidate an anti-inflammatory anti-cancer agent. class active site-directed plasmin inhibitors containing tranexamic acid residue has been de...
Melasma adalah kondisi hipermelanosit didapat berupa makula tidak merata yang umumnya simetris. Kondisi ini biasanya terlokalisasi dan bersifat kronik-residif. Di antara banyak faktor kausatif berperan pada patogenesis melasma, salah satu dianggap penting paparan sinar UV kulit. Pengobatan melasma penuh tantangan karena sering rekuren. Asam traneksamat plasmin inhibitor melalui sistem plasmin-a...
background: plasminogen is one of the compounds derived from human plasma. activation of plasminogen produces plasmin. plasmin is able to lyse fibrinogen, fibrin, and some other human plasma proteins. the aim of the present work was to study the separation of human plasminogen by affinity chromatography using gel lysine sepharose. materials and methods: normal human plasma was used as the start...
Background: Plasminogen has a central role in fibrinolyrtic system can activate through various activators (PAs) to its active form plasmin and perfoem its vital function that is fibrin clot lysis. Furthermore the fibrinolyrtic system plays a major role in angiogenesis. The fibrinolyrtic system activation control cell migration and invasion. In addition to this, plasmin regulates tumor growth. ...
alpha2-Plasmin inhibitor and alpha2-macroglobulin were allowed to compete for the protease plasmin. The binding of the enzyme to these inhibitors was assessed by two different but comparable methods. The interactions were completed in 10 s of incubation, and transfer of plasmin from one inhibitor to the other did not occur. Almost as much plasmin was bound to alpha2-plasmin inhibitor in mixture...
Binding of plasmin(ogen) to rat C6 glioma cells is saturable and kringle-domain dependent. This interaction was studied as a model of plasmin(ogen) receptor interactions in nucleated mammalian cells. Apparent 125I-plasmin dissociation from C6 cell binding sites was slow; however, the dissociation rate was increased when the solution contained diisopropyl phosphoryl-plasmin (0.3 microM), fibrino...
These studies demonstrate relatively rapid association of plasmin with thrombospondin and the effects of this interaction on plasmin activity towards D-Val-L-Leu-L-Lys p-nitroanilide hydrochloride (S-2251) and the proteinase inhibitors alpha 2-antiplasmin (alpha 2AP) and alpha 2-macroglobulin (alpha 2M). Binding of plasmin to thrombospondin reached an apparent reversible equilibrium within 3 mi...
We have previously reported that the serine protease plasmin generated during contact activation of human plasma triggers biosynthesis of leukotrienes (LTs) in human peripheral monocytes (PMs), but not in polymorphonuclear neutrophils (PMNs). We now show that purified plasmin acts as a potent chemoattractant on human monocytes, but not on PMNs. Human plasmin or plasminogen activated with urokin...
An enzyme-linked differential antibody immunosorbent assay has been developed for the quantification of alpha2-plasmin inhibitor-plasmin and alpha2-macroglobulin-plasmin complexes. In this method the inhibitor-plasmin complex is bound to a surface by an inhibitor-specific antibody, and the plasmin bound to the inhibitor is quantified by a second antibody, rabbit antiplasminogen F(ab')2, labeled...
A high-affinity surface receptor for human plasmin has been reported on certain group A streptococci. To map the region of the plasmin molecule that binds to the bacterial receptor, isolated domains of plasmin were tested for their ability to inhibit the binding of intact radiolabeled plasmin to receptor-positive bacteria. Complete inhibition of binding of labeled plasmin to bacteria by isolate...
