The Nijmegen Hemostasis Assay: Simultaneous Fluorogenic Measurement of Thrombin and Plasmin Generation in a Single Well
Published on: February 27, 2026
Summary
Acute promyelocytic leukemia (APL) involves coagulopathy. Supplementing with L-methionine, an amino acid aiding homocysteine metabolism, prevents fibrinolytic abnormalities in an APL mouse model.
Area of Science:
- Hematology
- Biochemistry
- Oncology
Background:
- Acute promyelocytic leukemia (APL) is characterized by a distinct coagulopathy.
- Fibrinolytic abnormalities contribute to the hemostatic challenges in APL.
Purpose of the Study:
- To investigate the potential of L-methionine supplementation in mitigating coagulopathy associated with APL.
- To explore the role of homocysteine metabolism in APL-related fibrinolysis.
Main Methods:
- Experiments were conducted using a validated mouse model of acute promyelocytic leukemia.
- The study assessed the effects of L-methionine supplementation on fibrinolytic parameters.
Main Results:
- L-methionine supplementation effectively prevented the development of fibrinolytic abnormalities in the APL mouse model.
- This suggests a link between homocysteine metabolism and fibrinolysis in APL pathogenesis.
Conclusions:
- L-methionine represents a potential therapeutic strategy for managing coagulopathy in acute promyelocytic leukemia.
- Targeting homocysteine metabolism may offer a novel approach to address fibrinolytic dysfunction in APL.

Anticoagulant Drugs: Low-Molecular-Weight Heparins
Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...
Coagulation
The coagulation phase is a critical part of the body's process to prevent blood loss following injury to blood vessels. It involves chemical reactions that form a clot to seal the injured area. The clotting process begins shortly after injury, within 15-20 seconds for severe damage and 1-2 minutes for minor injuries.
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...

Coagulation
Colloidal solids are solid particles suspended in solution. They are usually negatively charged, attracting a compact primary layer of positively charged ions, which attract more counterions to form an electrical double layer. Electrostatic repulsion between the charged double layers prevents the particles from colliding, stabilizing the colloids. These solids are often undesirable because they can contain toxins that are difficult to remove. Coagulation is a technique that helps aggregate and...
Venous Thrombosis III: Interprofessional Care
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
Clot Retraction and Fibrinolysis
After a fibrin clot is formed, the next step is clot retraction, a vital process facilitated by platelet contractile proteins, such as actin and myosin. These proteins pull the fibrin strands closer together and condense the clot. This action reduces the size of the clot, creating a smaller, denser structure that effectively seals off the damaged vessel. Clot retraction consolidates the clot and helps with wound healing by bringing the edges of the damaged blood vessel closer together.
Disorders of Hemostasis
Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.
