hsa04610	complement and_coagulation_cascades	Complement and coagulation cascades	Blood coagulation is a series of coordinated and calcium-dep...... Blood coagulation is a series of coordinated and calcium-dependent proenzyme-to-serine protease conversions likely to be localized on the surfaces of activated cells in vivo. It culminates in the formation of thrombin, the enzyme responsible for the conversion of soluble fibrinogen to the insoluble fibrin clot. The kallikrein-kinin system is an endogenous metabolic cascade, triggering of which results in the release of vasoactive kinins (bradykinin-related peptides). Kinin peptides are implicated in many physiological and pathological processes including the regulation of blood pressure and sodium homeostasis, inflammatory processes, and the cardioprotective effects of preconditioning. Complement is a system of plasma proteins that is activated by the presence of pathogens. There are three pathways of complement activation: the classical pathway, the lectin pathway, and the alternative pathway. All of these pathways generate a crucial enzymatic activity that, intern, generates the effector molecules of complement. The three main consequences of complement activation are the opsonization of pathogens, the recruitment of inflammatory and immunocompetent cells, and the direct killing of pathogens. More...

The p53 protein is employed as a transcriptional activator of p53-regulated genes. This results in three major outputs; cell cycle arrest, cellular senescence or apoptosis. Other p53-regulated gene functions communicate with adjacent cells, repair the damaged DNA or set up positive and negative feedback loops that enhance or attenuate the functions of the p53 protein and integrate these stress responses with other signal transduction pathways.

PLATELETAPP_PATHWAY	plateletapp pathway	Platelet Amyloid Precursor Protein Pathway	The amyloid -beta peptide (Ab), a proteolytic fragment of am...... The amyloid -beta peptide (Ab), a proteolytic fragment of amyloid precursor protein (APP), is the major componenet of senile plaques, the hallmark of alzhemiers disease. Platelets contain both APP and Ab and probably contribute greater than 90% of circulating APP. The soluble APP is the major inhibitor of coagulation factors IXa and XIa, and platelet aggregation. Agonists such as ADP, thrombin, epinephrine and collagen activate the release of APP and plasminogen activator inhibitor I (an important regulator of coagulation) from platelet storage granules. These important molecules released from platelets are key regulators of hemostasis, the physiologic arrest of hemorrhage at site of vascular leakage. More...
FIBRINOLYSIS_PATHWAY	fibrinolysis pathway	Fibrinolysis Pathway	Clot formation and fibrinolysis is a balance of plasmin acti...... Clot formation and fibrinolysis is a balance of plasmin activation/inhibition and thrombin-thrombomodulin activity that regulates fibrin polymer formation and degradation. Active thrombin is produced by the cleavage of prothrombin in the intrinsic thrombin activation pathway or the extrinsic thrombin activation pathway. Cleavage of fibrinogen by thrombin releases the fibrin monomers that auto-polymerize within seconds into fibrin threads or fibers. The coagulation cascade has many feedback loops. One example is the binding of thrombin to the fibrin polymers resulting in a reduction in soluble thrombin. The fibers form a more stable clot as a result of the covalent bonds formed by activated factor XIII enzyme (also known as Fibrin stabilizing factor). These fibers form a mesh the traps platelets, blood cells and plasma to form a clot. The removal of the clot is caused by plasmin cleavage of the fibrin monomers into soluble fibrin degradation products. Plasmin is formed by the cleavage of plasminogen between Arg561 and Val562. Plasmin is a two-chain trypsin-like serine protease. Plasminogen activator inhibitor 1 (PAI1) and plasminogen activator inhibitor 2 (PAI2) inhibit cleavage of plasminogen by tissue-type plasminogen activator (tPA) or urokinase plasminogen activator (uPA). The presence of fibrin fibers and fibrin degradation products exert a two-fold stimulation of tPA and uPA. Plasmin activity is also inhibited by alpha2-antiplasmin. Thrombin activatable fibrinolysis inhibitor (TAFI) is a carboxy-peptidase B-like proenzyme activated by the thrombin-thrombomodulin dimer. TAFI cleaves (DD)E2 to separate DD and E fragments which do not enhance the activation of tPA or uPA and results in a reduced feedback signal. Disease Significance: Overabundance or increased activity of the plamsminogen activator inhibitors or reduced presence or function of tPA or uPA can result in atherosclerotic disease and venous thrombosis due to an increase in fibrin deposition or formation of a thrombus. Thrombosis can also result from plasminogen deficiency caused by a lack of protein or lack of functional protein. Reduced or depleted levels of alpha2-antiplamin can result in severe bleeding disorders. More...

Gene mapped Reactome pathways
REACT_604	hemostasis	Two principal mechanisms limit blood loss after vascular inj...... Two principal mechanisms limit blood loss after vascular injury. Initially, platelets are activated, adhere to the site of the injury, and aggregate into a plug that limits blood loss. Proteins and small molecules released from activated platelets stimulate the plug formation process, and fibrinogen from the plasma forms bridges between activated platelets. These events allow the initiation of the clotting cascade, the second mechanism to limit blood loss. Negatively charged phospholipids exposed on cell surfaces at the site of injury and on activated platelets interact with tissue factor, setting off a cascade of reactions leading to generation of fibrin and the formation of an insoluble fibrin clot that strengthens the platelet plug. More...
REACT_318	platelet degranulation	Platelets function as exocytotic cells, secreting a plethora...... Platelets function as exocytotic cells, secreting a plethora of effector molecules at sites of vascular injury. Platelets contain a number of distinguishable storage granules including alpha granules, dense granules and lysosomes. On activation platelets release a variety of proteins, largely from storage granules but also as the result of apparent cell lysis. These act in an autocrine or paracrine fashion to modulate cell signaling. Alpha granules contain mainly polypeptides such as fibrinogen, von Willebrand factor, growth factors and protease inhibitors that that supplement thrombin generation at the site of injury. Dense granules contain small molecules, particularly adenosine diphosphate (ADP), adenosine triphosphate (ATP), serotonin and calcium, all recruit platelets to the site of injury. More...
REACT_20	formation of_platelet_plug	Hemostasis is a physiological response that culminates in th...... Hemostasis is a physiological response that culminates in the arrest of bleeding from an injured vessel. Acute vessel injury results in its constriction to reduce the loss of blood. Under normal conditions vascular endothelium supports vasodilation, inhibits platelet adhesion and activation, suppresses coagulation, enhances fibrin cleavage and is anti-inflammatory in character. Under acute vascular trauma vasoconstrictor mechanisms predominate and the endothelium becomes prothrombotic, procoagulatory and proinflammatory in nature. This is achieved by a reduction of endothelial dilating agents: adenosine, NO and prostacyclin; and the direct action of ADP, serotonin and thromboxane on vascular smooth muscle cells to elicit their contraction. The chief trigger for the change in endothelial function that leads to the formation of haemostatic thrombus is the loss of the endothelial cell barrier between blood and ECM components. Circulating platelets identify and discriminate areas of endothelial lesions; here, they adhere to the exposed sub endothelium. Their interaction with the various thrombogenic substrates and locally generated or released agonists results in platelet activation. This process is described as possessing two stages, firstly, adhesion - the initial tethering to a surface, and secondly aggregation - the platelet-platelet cohesion. More...
REACT_798	platelet activation	Platelet activation begins with the initial binding of adhes...... Platelet activation begins with the initial binding of adhesive ligands and of the excitatory platelet agonists. Intracellular signaling reactions will then enhance the adhesive and procoagulant properties of tethered platelets or of platelets circulating in the proximity. From the subendothelial adhesive substrates, collagen and possibly vWF are the main inducers of platelet activation. GP VI is the most potent collagen receptor initiating signal generation, an ability derived from its interaction with the FcRI gamma chain. This results in the phosphorylation of the gamma-chain by the non-receptor tyrosine kinases of the Src family. The phosphotyrosine motif is recognized by the SH2 domains of Syk, a tyrosine kinase. This association activates the Syk enzyme, leading to activation. Four PARs are identified, of which PARs 1 ,3 and 4 are substrates for thrombin. PAR 1 is the predominant thrombin receptor, PAR 3 is minimally expressed and PAR 4 is less responsive to thrombin. Platelets do not store PAR1, due to limited protein synthesis, they are capable of responding to thrombin only once. Platelet activation further results in the scramblase-mediated transport of negatively-charged phospholipids to the platelet surface. These phospholipids provide a catalytic surface (with the charge provided by phosphatidylserine and phosphatidylethanolamine) for the tenase complex (formed by the activated forms of the blood coagulation factors factor VIII and factor I).
