Coagulation, also known as clotting, is the process by which blood changes from a liquid to a gel, forming a blood clot. It results in hemostasis, the cessation of blood loss from a damaged vessel, followed by repair. The process of coagulation involves activation, adhesion and aggregation of platelets, as well as deposition and maturation of ...
Acute promyelocytic leukemia is characterized by a chromosomal translocation involving the retinoic acid receptor alpha (RARA) gene on chromosome 17. [3] In 95% of cases of APL, the RARA gene on chromosome 17 is involved in a reciprocal translocation with the promyelocytic leukemia gene (PML) on chromosome 15, a translocation denoted as t(15;17)(q22;q21).

Thrombomodulin (TM), CD141 or BDCA-3 is an integral membrane protein expressed on the surface of endothelial cells and serves as a cofactor for thrombin. It reduces blood coagulation by converting thrombin to an anticoagulant enzyme from a procoagulant enzyme. [5]
Disseminated intravascular coagulation (DIC) is a condition in which blood clots form throughout the body, blocking small blood vessels. [1] Symptoms may include chest pain , shortness of breath , leg pain, problems speaking, or problems moving parts of the body. [ 1 ]
Coagulative necrosis is most commonly caused by conditions that do not involve severe trauma, toxins or an acute or chronic immune response.The lack of oxygen (hypoxia) causes cell death in a localized area which is perfused by blood vessels failing to deliver primarily oxygen, but also other important nutrients.
The last category, alterations in the constitution of blood, [6] has numerous possible risk factors such as hyperviscosity, coagulation factor V Leiden mutation, coagulation factor II G2021A mutation, deficiency of antithrombin III, protein C or S deficiency, nephrotic syndrome, changes after severe trauma or burn, cancer, late pregnancy and ...
Coagulation factor V (Factor V), also less commonly known as proaccelerin or labile factor, is a protein involved in coagulation, encoded, in humans, by F5 gene. [5] In contrast to most other coagulation factors, it is not enzymatically active but functions as a cofactor . [ 5 ]
Cancer procoagulant is a hypothesised protein, most likely a cysteine protease enzyme (EC 3.4.22.26), that occurs only in fetal and malignant cells. Its activity appears to be the activation of factor X, one of the coagulation factors, and would account for the increased incidence of thrombosis in cancer patients.
