The phospholipase A1 activity of lysophospholipase A-I links platelet activation to LPA production during blood coagulation.
Platelet activation initiates an upsurge in polyunsaturated (18:2 and 20:4) lysophosphatidic acid (LPA) production. The biochemical pathway(s) responsible for LPA production during blood clotting are not yet fully understood. Here we describe the purification of a phospholipase A(1) (PLA(1)) from thrombin-activated human platelets using sequential chromatographic steps followed by fluorophospho...
متن کاملPlatelet activation and blood coagulation.
Platelet activation and blood coagulation are complementary, mutually dependent processes in haemostasis and thrombosis. Platelets interact with several coagulation factors, while the coagulation product thrombin is a potent platelet-activating agonist. Activated platelets come in a procoagulant state after a prolonged elevation in cytosolic [Ca2+]i. Such platelets, e.g. when adhering to collag...
متن کاملConstitutive and lysophosphatidic acid (LPA)-induced LPA production: role of phospholipase D and phospholipase A2.
Ascitic fluid and plasma from ovarian cancer patients, but not from patients with nongynecological tumors, contain elevated levels of the bioactive phospholipid lysophosphatidic acid (LPA). We show that ovarian cancer cells constitutively produce increased amounts of LPA as compared with normal ovarian epithelium, the precursor of ovarian epithelial cancer, or breast cancer cells. In addition, ...

متن کاملSystems Biology of Blood Coagulation and Platelet Activation
Blood clotting is a highly conserved physiological response that prevents excessive blood loss following vessel injury. It involves a sequence of plasma reactions leading to the formation of thromin (the coagulation cascade) as well as tightly controlled intracellular reactions mediating platelet activation. These two events are inextricably coupled, with the active platelet surface serving as ...
