To critically examine the role of protein lactylation (Kla) in myocardial ischemia-reperfusion injury (MIRI) and discuss potential therapeutic strategies targeting this mechanism.
Approach:
Literature Review: The review synthesizes current findings on Kla's involvement in MIRI, analyzing mechanisms and evaluating translational potential.
Key Findings:
MIRI is a significant complication in cardiovascular therapy, often exacerbated by reperfusion.
Kla is a post-translational modification linked to lactate metabolism that affects cardiomyocyte survival.
Kla regulates key pathways related to cell death, inflammation, and cardiac remodeling.
Lactate accumulation during ischemia serves as a substrate for protein lactylation, linking metabolism to gene regulation.
Interpretation:
Kla represents an active adaptive mechanism in cardiomyocytes responding to ischemic stress, influencing various biological processes.
Limitations:
Current understanding of Kla's role in MIRI is limited and lacks comprehensive synthesis.
There is a translational gap between preclinical findings and clinical cardioprotection.
Conclusion:
The review highlights the need for further research on Kla to inform the development of novel therapeutic strategies for MIRI.
For many people, cardiovascular disease develops silently. It can remain undetected for years, overshadowed by an active lifestyle and an apparent lack of symptoms.
