1 Interaction of fibrinogen with saphenous vein endothelial cells stimulates tyrosine phosphorylation of cortactin. Tyrosine fibrinogen beta chain Homo sapiens
2 We have investigated the effect of fibrinogen on the tyrosine phosphorylation of cortactin, a cytoskeletal protein in human saphenous vein endothelial cells (HSVECs). Tyrosine fibrinogen beta chain Homo sapiens
3 Incubation of HSVECs with fibrinogen (0-4 microM) caused a concentration-dependent increase in the tyrosine phosphorylation of cortactin. Tyrosine fibrinogen beta chain Homo sapiens
4 Fibrinogen (4 microM) and fibrinogen fragment D (4 microM) caused 250% and >450% increase in tyrosine phosphorylation of cortactin respectively, but fibrinogen fragment E (50 kDa form) was ineffective. Tyrosine fibrinogen beta chain Homo sapiens
5 Fibrinogen (4 microM) and fibrinogen fragment D (4 microM) caused 250% and >450% increase in tyrosine phosphorylation of cortactin respectively, but fibrinogen fragment E (50 kDa form) was ineffective. Tyrosine fibrinogen beta chain Homo sapiens
6 At physiological concentrations fibrinogen binds to receptors (probably including ICAM-1) on HSVECs, to increase tyrosine phosphorylation of cortactin. Tyrosine fibrinogen beta chain Homo sapiens
