| Gene Target | Biological Function | Application as a Biomarker |
|---|---|---|
| coagulation factor II, thrombin (F2) | Coagulation factor II, also known as thrombin, is a serine protease that plays a central role in the coagulation cascade. It is synthesized in the liver as an inactive precursor, prothrombin, which is converted to active thrombin by the prothrombinase complex during the coagulation process. Thrombin's primary function is to convert soluble fibrinogen into insoluble fibrin, leading to clot formation. Additionally, thrombin activates other coagulation factors (V, VIII, XI, XIII), stimulates platelet aggregation, and modulates various cellular responses through protease-activated receptors. Its activity is tightly regulated to maintain hemostasis and prevent pathological thrombosis. | Measurement of prothrombin (F2) levels, activity, or its activation products is used in clinical settings to assess coagulation status. Prothrombin time (PT) is a widely used laboratory test that evaluates the extrinsic pathway of coagulation and is influenced by prothrombin concentration and function. Altered levels or activity of F2 can indicate coagulation disorders, such as deficiencies leading to bleeding diatheses or increased thrombin generation associated with thrombotic risk. F2 gene mutations, such as the G20210A variant, are associated with increased risk of venous thromboembolism and are used in genetic risk assessment. |
| coagulation factor IX (F9) | Coagulation factor IX (F9) is a vitamin K-dependent serine protease that plays a critical role in the blood coagulation cascade. It is synthesized in the liver as an inactive zymogen and, upon activation by factor XIa or the factor VIIa-tissue factor complex, becomes active factor IXa. Activated factor IXa, in conjunction with its cofactor factor VIIIa, calcium ions, and phospholipids, forms the intrinsic tenase complex, which catalyzes the conversion of factor X to its active form, factor Xa. This activation is a key step in the propagation phase of coagulation, ultimately leading to the generation of thrombin and the formation of a stable blood clot. Mutations or deficiencies in the F9 gene result in hemophilia B, a hereditary bleeding disorder. | Measurement of coagulation factor IX levels and activity is utilized in the diagnosis and classification of hemophilia B, as well as in the monitoring of replacement therapy in affected individuals. Factor IX assays are also employed to assess liver synthetic function, screen for vitamin K deficiency, and evaluate potential causes of abnormal bleeding or thrombosis. In addition, F9 genetic analysis is used to confirm hemophilia B and for carrier detection in at-risk individuals. |
| coagulation factor VII (F7) | Coagulation factor VII (F7) is a vitamin K-dependent serine protease that plays a critical role in the initiation of the extrinsic pathway of blood coagulation. Upon vascular injury, F7 circulates in the plasma as an inactive zymogen and becomes activated (factor VIIa) after limited proteolysis. Activated F7 binds to tissue factor (TF) exposed at the site of injury, forming the TF-FVIIa complex. This complex then activates factor IX and factor X, leading to the generation of thrombin and the formation of a fibrin clot. Regulation of F7 activity is essential for maintaining hemostasis and preventing excessive bleeding or thrombosis. | Measurement of F7 levels or activity in plasma is utilized in the assessment of coagulation status. F7 is used in the diagnosis and monitoring of congenital factor VII deficiency, a rare bleeding disorder characterized by reduced F7 activity. Additionally, F7 activity assays are part of the evaluation of unexplained bleeding or prolonged prothrombin time (PT). Elevated F7 levels have been studied in relation to thrombotic risk and cardiovascular disease, and F7 activity may be assessed in the context of liver function, as the liver synthesizes this protein. |
| coagulation factor VIII (F8) | Coagulation factor VIII (F8) is a glycoprotein that plays a critical role in the blood coagulation cascade. It acts as a cofactor for factor IXa, which, in the presence of calcium ions and phospholipids, converts factor X to the activated form Xa. This step is essential for the generation of thrombin and the formation of a stable fibrin clot. F8 circulates in plasma in an inactive form bound to von Willebrand factor, which protects it from degradation. Upon vascular injury, F8 is activated by thrombin, dissociates from von Willebrand factor, and participates in the propagation of the coagulation cascade. Deficiency or dysfunction of F8 results in hemophilia A, a hereditary bleeding disorder. | Measurement of coagulation factor VIII activity or antigen levels is used in the clinical assessment of bleeding disorders, particularly for the diagnosis and classification of hemophilia A. F8 levels are also evaluated in the context of acquired bleeding disorders and can be assessed to monitor replacement therapy in patients with hemophilia A. Additionally, elevated F8 levels have been associated with an increased risk of thrombotic events, such as venous thromboembolism, and may be considered in the evaluation of patients with unexplained thrombosis. |
| coagulation factor X (F10) | Coagulation factor X (F10) is a vitamin K-dependent serine protease that plays a central role in the blood coagulation cascade. Upon activation to factor Xa, F10 converts prothrombin (factor II) to thrombin in the presence of factor Va, calcium ions, and phospholipids. Thrombin then converts fibrinogen to fibrin, leading to clot formation. F10 is synthesized in the liver and circulates in plasma as an inactive zymogen. Its activation represents a critical step in both the intrinsic and extrinsic coagulation pathways, serving as the point of convergence for these pathways. | Measurement of F10 activity or antigen levels in plasma is used in the evaluation of coagulation disorders. Reduced F10 activity can indicate inherited or acquired factor X deficiency, which is associated with bleeding tendencies. F10 levels can also be affected in liver disease, vitamin K deficiency, or during anticoagulant therapy (e.g., with vitamin K antagonists or direct oral factor Xa inhibitors). Monitoring F10 activity may aid in diagnosing bleeding disorders, assessing liver function, and evaluating the pharmacodynamic effects of anticoagulant medications. |
| interleukin 1 beta (IL1B) | Interleukin 1 beta (IL1B) is a pro-inflammatory cytokine produced primarily by activated macrophages, as well as other cell types such as monocytes, dendritic cells, and epithelial cells. It is synthesized as an inactive precursor (pro-IL1B) and is cleaved by caspase-1 in the inflammasome complex to generate the active form. IL1B plays a central role in mediating the inflammatory response by promoting the expression of adhesion molecules on endothelial cells, inducing the production of other cytokines and chemokines, and stimulating the activation and recruitment of immune cells. It also contributes to fever induction, the acute phase response, and the regulation of cell proliferation, differentiation, and apoptosis. | IL1B has been used as a biomarker of inflammation in various clinical and research settings. Elevated levels of IL1B in blood, tissue, or other biological fluids have been associated with a range of inflammatory and autoimmune conditions, including rheumatoid arthritis, sepsis, inflammatory bowel disease, and certain infectious diseases. Measurement of IL1B can assist in assessing the extent of inflammatory activity, monitoring disease progression, and evaluating responses to anti-inflammatory therapies. |
| plasminogen (PLG) | Plasminogen (PLG) is a glycoprotein produced primarily by the liver and released into the bloodstream as an inactive zymogen. It is the precursor of plasmin, a serine protease that plays a central role in fibrinolysis, the process responsible for the breakdown of fibrin clots. Upon activation by tissue-type or urokinase-type plasminogen activators (tPA or uPA), plasminogen is converted to plasmin, which degrades fibrin into soluble degradation products. In addition to its role in clot dissolution, plasminogen/plasmin participates in tissue remodeling, wound healing, cell migration, and modulation of inflammatory responses. | Plasminogen levels and activity are measured in clinical settings to assess disorders of fibrinolysis. Deficiency or dysfunction of plasminogen is associated with rare conditions such as congenital plasminogen deficiency (hypoplasminogenemia), which can result in abnormal fibrin accumulation and related lesions. Altered plasminogen or plasmin activity has also been studied in the context of thrombotic or bleeding disorders, liver disease, and certain inflammatory conditions. Measurement of plasminogen can aid in the evaluation of the fibrinolytic system and in distinguishing between different causes of coagulopathy. |
| tissue factor pathway inhibitor (TFPI) | Tissue factor pathway inhibitor (TFPI) is a key endogenous regulator of the extrinsic coagulation pathway. It is a Kunitz-type serine protease inhibitor that primarily inhibits the tissue factor (TF)-factor VIIa complex and factor Xa. TFPI is synthesized mainly by endothelial cells and circulates in plasma, where it controls thrombin generation by restricting the initiation of blood coagulation. By binding to factor Xa, TFPI forms a complex that subsequently inhibits the TF-factor VIIa complex, thereby providing negative feedback regulation of coagulation and maintaining hemostatic balance. | TFPI levels in plasma have been studied as a biomarker in various clinical contexts, particularly in disorders related to coagulation and thrombosis. Altered TFPI concentrations have been observed in conditions such as venous thromboembolism, sepsis, disseminated intravascular coagulation, and certain cardiovascular diseases. Measurement of TFPI can provide information about the status of coagulation regulation and endothelial function, and has been investigated in relation to risk assessment, disease progression, and response to anticoagulant therapies. |
| von Willebrand factor (VWF) | Von Willebrand factor (VWF) is a large multimeric glycoprotein primarily synthesized by endothelial cells and megakaryocytes. VWF plays a critical role in hemostasis by mediating the adhesion of platelets to sites of vascular injury. It serves as a bridge between subendothelial collagen and platelet surface receptors, facilitating platelet plug formation. Additionally, VWF binds and stabilizes coagulation factor VIII in circulation, protecting it from proteolytic degradation and thereby supporting the intrinsic coagulation pathway. | VWF is commonly measured in plasma to assess endothelial cell activation or injury, as well as to evaluate disorders of hemostasis. Elevated levels of VWF have been associated with endothelial dysfunction and are observed in various conditions such as thrombotic microangiopathies, cardiovascular disease, and inflammatory states. Conversely, reduced levels or functional defects in VWF are characteristic of von Willebrand disease, a bleeding disorder. Quantification of VWF antigen and activity is utilized in the diagnostic workup of bleeding or thrombotic disorders. |
