Importance of long non-coding RNAs in the pathogenesis, diagnosis, and treatment of myocardial infarction

Abstract

Myocardial infarction (MI), a major global cause of mortality and morbidity, continues to pose a significant burden on public health. Despite advances in understanding its pathogenesis, there remains a need to elucidate the intricate molecular mechanisms underlying MI progression. Long non-coding RNAs (lncRNAs) have emerged as key regulators in diverse biological processes, yet their specific roles in MI pathophysiology remain elusive. Conducting a thorough review of literature using PubMed and Google Scholar databases, we investigated the involvement of lncRNAs in MI, focusing on their regulatory functions and downstream signaling pathways. Our analysis revealed extensive dysregulation of lncRNAs in MI, impacting various biological processes through diverse mechanisms. Notably, lncRNAs act as crucial modulators of gene expression and signaling cascades, functioning as decoys, regulators, and scaffolds. Furthermore, studies identified the multifaceted roles of lncRNAs in modulating inflammation, apoptosis, autophagy, necrosis, fibrosis, remodeling, and ischemia–reperfusion injury during MI progression. Recent research highlights the pivotal contribution of lncRNAs to MI pathogenesis, offering novel insights into potential therapeutic interventions. Moreover, the identification of circulating lncRNA signatures holds promise for the development of non-invasive diagnostic biomarkers. In summary, findings underscore the significance of lncRNAs in MI pathophysiology, emphasizing their potential as therapeutic targets and diagnostic tools for improved patient management and outcomes.
