Abstract

Insights

Elevated matrix metalloproteinase-12 (MMP-12) is linked to increased risk of aortic dissection (AD) and aortic aneurysm (AA). This study used Mendelian randomization to confirm MMP-12 as a potential therapeutic target for these conditions.

Area of Science:

  • Cardiovascular Genetics
  • Proteomics
  • Epidemiology

Background:

  • Elevated matrix metalloproteinase-12 (MMP-12) levels are observed in patients with aortic dissection (AD) and aortic aneurysm (AA).
  • The precise association between MMP-12 and the development of AD and AA requires further investigation.
  • Understanding this relationship is crucial for identifying potential therapeutic targets.

Purpose of the Study:

  • To clarify the role of MMP-12 in the formation of AD and AA.
  • To verify the correlation between MMP-12 and AD/AA development at the genetic level using Mendelian randomization (MR) analysis.

Main Methods:

  • Utilized the Integrative Epidemiology Unit (IEU) OpenGWAS database for MMP-12 genetic data (n=21,758 European residents).
  • Retrieved genetic variation data for AD and AA from the FinnGen database.
  • Employed forward and reverse Mendelian randomization analyses, primarily using the inverse-variance weighting (IVW) method.

Main Results:

  • Forward MR analysis indicated a positive correlation between serum MMP-12 levels and increased risk of AD (OR=1.301, P=0.048) and AA (OR=1.121, P=0.04).
  • Reverse MR studies found no significant genetic relationships between AD/AA and MMP-12 levels.
  • No significant heterogeneity or pleiotropy was detected in the MR analyses.

Conclusions:

  • A significant correlation exists between serum MMP-12 levels and the risk of developing AD and AA.
  • MMP-12 emerges as a potential therapeutic target for managing AD and AA.
  • Genetic evidence supports a causal link between MMP-12 and the pathogenesis of aortic diseases.
