Mevalonic acid exerts procoagulant effect by potentiating factor Xa

Area of Science:

• Biochemistry
• Hematology
• Metabolic pathways

Background:

• Thrombosis pathogenesis involves lipid metabolism and inflammation.
• The mevalonate pathway's role in coagulation is poorly understood.

Purpose of the Study:

• To investigate the regulatory effects of mevalonic acid (MVA) on the coagulation system.
• To elucidate the direct impact of MVA on hemostasis and thrombosis.

Main Methods:

• Recalcification assays and enzymatic kinetic analysis to determine MVA's effect on coagulation.
• In vivo studies using mouse models for bleeding and thrombosis.
• Identification of coagulation targets through natural substrate hydrolysis assays.

Main Results:

• MVA significantly accelerates plasma coagulation by potentiating Factor Xa (FXa) procoagulant activity.
• MVA shortened activated partial thromboplastin time and prothrombin time, reducing bleeding time.
• MVA administration potentiated thrombus formation in ferric chloride-induced thrombosis, deep vein thrombosis, and cerebral infarction models.

Conclusions:

• Mevalonic acid directly regulates FXa procoagulant activity, linking lipid metabolism to coagulation.
• Findings suggest crosstalk between lipid metabolism and inflammatory signaling in coagulation.
• The mevalonate pathway represents a potential therapeutic target for thrombotic complications in metabolic disorders.
