What is PAI-1 gene polymorphism?
The PAI-1 4G/5G polymorphism is a DNA sequence variation that plays a key role in regulating PAI-1 gene expression. Studies have shown that the PAI-1 activity of the 4G allele promoter is higher than that of the 5G allele promoter in a cytokine-stimulated state.
What is PAI-1 4G 5G mutation?
The 4G/5G polymorphism is a common polymorphism in the promoter region of the PAI-1 gene. Both the 4G and 5G alleles have a binding site for an activator of transcription. The 5G allele, however, has an additional binding site for a repressor, resulting in lower transcription rates and less PAI-1 activity.
How does PAI-1 affect pregnancy?
During a healthy pregnancy, PAI-1 levels in the plasma gradually elevate during the second trimester of pregnancy and reach a maximum at 32–40 weeks of pregnancy. Within 5–8 weeks after delivery, PAI-1 levels fall again to the levels before the occurrence of pregnancy [2].
Is Pai 1 a blood clotting disorder?
Plasminogen activator inhibitor type 1 (PAI1) deficiency is a rare bleeding disorder that causes excessive or prolonged bleeding due to blood clots being broken down too early. PAI1 is a protein in the body needed for normal blood clotting.
What is the PAI gene?
Expand Section. Complete PAI-1 deficiency is caused by mutations in the SERPINE1 gene. This gene provides instructions for making a protein called plasminogen activator inhibitor 1 (PAI-1). PAI-1 is involved in normal blood clotting (hemostasis ).
What are the heterozygous genotypes?
(HEH-teh-roh-ZY-gus JEE-noh-tipe) The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).
What is homozygous state?
Homozygous describes the genetic condition or the genetic state where an individual has inherited the same DNA sequence for a particular gene from both their biological mother and their biological father. It's often used in the context of disease.
What is Pai 1 5G 5G genotype?
Plasminogen activator inhibitor-1 5G/5G genotype is associated with early spontaneous recanalization of the infarct-related artery in patients presenting with acute ST-elevation myocardial infarction.
What is 4G 4G Pai?
The 4G/4G polymorphism of the plasminogen activator inhibitor-1 (PAI-1) gene as an independent risk factor for placental insufficiency, which triggers fetal hemodynamic centralization. Ceska Gynekol.
What is Hypofibrinolysis?
Hypofibrinolysis causes impaired clot break-down, leading to thrombosis. This can be caused by the production of auto-antibodies against plasminogen activators (such as tPA and uPA), or against fibrinolytic receptor components (such as annexin).
What are PAI-1 levels?
Increased PAI-1 levels may predispose patients to the formation of atherosclerotic plaques prone to rupture with a high lipid-to-vascular smooth muscle cells ratio as a result of decreased cell migration. In humans, there is clinical evidence that increased PAI-1 levels are associated with atherothrombosis.
How do I lower my PAI-1 level?
In vitro studies have shown that statins increase tPA and decrease PAI-1 levels. This effect involves geranylgeranyl transferase inhibition. The mechanism by which statins treatment reduces PAI-1 is different from those that increase t-PA (16).
How do I treat Pai?
Medications/Treatment
PAI-1 deficiency can be safely and efficiently managed with antifibrinolytic therapy. Both epsilon-amino caproic acid (EACA) and tranexamic acid (TA) have been documented to control and prevent bleeding. Antifibrinolytic agents inhibit plasmin generation and are not derived from blood products.
