Insights
Non-coding RNAs (ncRNAs) are crucial in regulating inflammation during acute myocardial infarction (AMI) and ischemia-reperfusion (I/R) injury. Targeting ncRNAs offers promising therapeutic strategies for advancing AMI and I/R treatment.
Area of Science:
- Cardiovascular Biology
- Molecular Medicine
- RNA Biology
Background:
- Acute myocardial infarction (AMI) and ischemia-reperfusion (I/R) injury are significant causes of morbidity and mortality.
- Inflammation is a central pathological mechanism in AMI and I/R injury.
- Non-coding RNAs (ncRNAs) are increasingly recognized for their roles in regulating inflammatory processes.
Purpose of the Study:
- To highlight the critical roles of miRNAs and competitive endogenous RNAs (ceRNAs) in myocardial infarction (MI) and I/R injury progression.
- To explore the therapeutic potential of targeting ncRNAs in MI and I/R injury.
- To provide an overview of current and emerging therapeutic strategies for ncRNA-based interventions.
Main Methods:
- Literature review focusing on the role of ncRNAs in myocardial inflammation.
- Analysis of miRNA and ceRNA involvement in the pathogenesis of MI and I/R injury.
- Examination of therapeutic approaches targeting ncRNAs, including pharmacological, herbal, and stem cell-based methods.
Main Results:
- Abnormal ncRNA expression exacerbates inflammatory responses in MI and I/R injury.
- miRNAs and ceRNAs are key regulators in the progression of MI and I/R.
- Various therapeutic strategies targeting ncRNAs show potential for alleviating inflammation and treating MI/R.
Conclusions:
- ncRNAs, particularly miRNAs and ceRNAs, are pivotal in the inflammatory cascade of MI and I/R injury.
- Targeting ncRNAs presents a promising avenue for novel therapeutic interventions in cardiovascular diseases.
- Further research into ncRNA-based therapies could significantly advance the treatment of acute myocardial infarction and ischemia-reperfusion injury.
Background:
Acute myocardial infarction (AMI) is a major contributor to both morbidity and mortality, resulting from the abrupt blockage of a coronary artery. Myocardial reperfusion refers to the re-establishment of coronary bloodflow following a period of coronary occlusion, which may provoke an intensified and rapid injury to the myocardium, known as ischaemia-reperfusion (I/R) injury. Inflammation is a key feature of myocardial infarction (MI) and I/R injury, playing a central role among the pathological mechanisms involved in AMI and MI/R injury. Non-coding RNAs (ncRNAs), such as microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), constitute a significant portion of the transcribed genome, with their essential roles and potential in regulating and resolving inflammation now well established. Abnormal ncRNA expression has been linked to worsening inflammatory processes and plays a role in the pathogenesis of MI and MI/R injury.
Aim Of Review And Conclusions:
This study emphasises the essential roles of miRNAs and competitive endogenous RNAs (ceRNAs) in the progression of MI and MI/R. In addition, our final section provides an in-depth analysis of the therapeutic targeting of ncRNAs through various methods, including pharmacological interventions, herbal medicine, and exosome-derived stem cell applications aimed at alleviating inflammation and possibly advancing MI treatment.
