MicroRNA-322-5p protects against myocardial infarction through targeting BTG2
Background
Numerous studies have explored the therapeutic potential of microRNA (miR) in myocardial infarction (MI) treatment. This study focuses on the role of miR-322-5p in MI, particularly in its regulatory interaction with B-cell translocation gene 2 (BTG2).
Materials and methods
Expression levels of miR-322-5p and BTG2 were assessed in a rat MI model. Adenovirus altering miR-322-5p or BTG2 expression were administered to MI rats. Evaluation included cardiac function, inflammation, myocardial injury, pathological changes, apoptosis, and NF-κB pathway-related genes in MI rats post-targeted treatment. The miR-322-5p and BTG2 targeting relationship was investigated.
Results
MI rats exhibited low miR-322-5p and high BTG2 expression in the myocardial tissues. Restoration of miR-322-5p enhanced cardiac function, alleviated inflammation and myocardial injury, mitigated pathological changes and apoptosis, and deactivated the NF-κB pathway in MI rats. BTG2 expression was negatively-regulated by miR-322-5p. Overexpressed BTG2 counteracted miR-322-5p-induced cardioprotection on MI rats.
Conclusion
This study provides evidence that miR-322-5p protects against MI by suppressing BTG2 expression.
