Coagulation factor V and thrombophilia: background and mechanisms

Area of Science:

• Biochemistry
• Hematology
• Molecular Biology

Background:

• Human coagulation factor V (FV) is a key protein in hemostasis, regulating both pro-coagulant and anti-coagulant pathways.
• Dysregulation of FV function can result in severe bleeding disorders or life-threatening thromboembolic conditions.
• The discovery of activated protein C (APC) resistance, particularly the factor V Leiden mutation, has intensified research into FV's role in thrombosis.

Purpose of the Study:

• To review the expression and regulation of human coagulation factor V functions.
• To provide a comprehensive overview of FV's role in the development of thromboembolic disease.

Main Methods:

• Literature review of scientific publications on coagulation factor V.
• Analysis of genetic mutations affecting FV function, such as the factor V Leiden mutation.
• Examination of the interplay between FV, APC resistance, and thrombotic events.

Main Results:

• FV plays a dual role in hemostasis, essential for normal blood clotting.
• Mutations in FV, like factor V Leiden, disrupt regulatory pathways, increasing thrombosis risk.
• Understanding FV regulation is critical for managing bleeding and clotting disorders.

Conclusions:

• Factor V is central to hemostasis and its dysregulation has significant clinical implications.
• The factor V Leiden mutation is a prominent example of how genetic alterations in FV contribute to thrombophilia.
• Further research into FV function and regulation is vital for advancing the treatment of coagulation disorders.
