We investigated the effect of plasmin on the release of glycosaminoglycans (GAG) from bovine aortic endothelial cells in culture. Plasmin significantly increased the release of [35S]sulphate-labelled GAG (35S-GAG) from the cell layer, although plasminogen did not show such a stimulatory effect. The percentage of heparan sulphate in the released 35S-GAG (about 80%) was not changed by plasmin. Plasmin enhanced the detachment of endothelial cells from the monolayer only slightly. From these results, it was suggested that the local anticoagulant activity on endothelium mediated by the anticoagulant heparan sulphate will be increased by plasmin; the conversion of plasminogen to plasmin may be mediated by plasminogen activators released from thrombin-stimulated endothelial cells.

UI	MeSH Term	Description	Entries
D007700	Kinetics	The rate dynamics in chemical or physical systems.
D010958	Plasminogen	Precursor of plasmin (FIBRINOLYSIN). It is a single-chain beta-globulin of molecular weight 80-90,000 found mostly in association with fibrinogen in plasma; plasminogen activators change it to fibrinolysin. It is used in wound debriding and has been investigated as a thrombolytic agent.

D005341	Fibrinolysin	A product of the lysis of plasminogen (profibrinolysin) by PLASMINOGEN activators. It is composed of two polypeptide chains, light (B) and heavy (A), with a molecular weight of 75,000. It is the major proteolytic enzyme involved in blood clot retraction or the lysis of fibrin and quickly inactivated by antiplasmins.

D006025	Glycosaminoglycans	Heteropolysaccharides which contain an N-acetylated hexosamine in a characteristic repeating disaccharide unit. The repeating structure of each disaccharide involves alternate 1,4- and 1,3-linkages consisting of either N-acetylglucosamine (see ACETYLGLUCOSAMINE) or N-acetylgalactosamine (see ACETYLGALACTOSAMINE).
