Matrix Metalloproteinases Family Gene Polymorphisms Are Associated with Thrombosis Risk in Myeloproliferative...

Area of Science:

• Hematology
• Genetics
• Vascular Biology

Background:

• Myeloproliferative neoplasms (MPNs) are blood cancers causing excessive myeloid cell growth and high thrombosis risk.
• Matrix metalloproteinases (MMPs) are enzymes involved in inflammation and vascular processes, potentially influencing thrombosis.

Purpose of the Study:

• To investigate the association between specific MMP gene polymorphisms and thrombotic risk in MPN patients.
• To identify potential genetic markers for predicting vascular complications in MPNs.

Main Methods:

• Genotyping of selected MMP polymorphisms (rs1799750, rs243865, rs3025058, rs3918242, rs17576) using PCR-RFLP.
• Analysis of the association between genotypes and thrombotic events (arterial and venous) in MPN patients.

Main Results:

• The MMP-9 rs3918242 CT genotype showed a significant association with increased arterial thrombosis risk (OR=4.206, p=0.014).
• This genotype was also linked to overall thrombotic events in MPN patients (OR=3.200, p=0.031), suggesting a role in the prothrombotic state.

Conclusions:

• Genetic variations in MMP-9, particularly the rs3918242 polymorphism, may contribute to the prothrombotic phenotype in MPNs.
• MMP-9 rs3918242 could serve as a predictive marker for vascular complications in MPN patients, warranting further investigation in larger cohorts.
