Insights
MicroRNAs (miRNAs) play a crucial role in cardiovascular disease (CVD) by influencing atherosclerosis. Modulating these small RNAs offers a promising therapeutic strategy for treating conditions like ischemic heart disease.
Area of Science:
- Biochemistry
- Molecular Biology
- Cardiology
Background:
- Cardiovascular disease (CVD) is a leading cause of mortality, with atherosclerosis being its primary driver.
- MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression post-transcriptionally.
- Dysregulation of miRNAs is implicated in all stages of atherosclerotic plaque development and destabilization.
Purpose of the Study:
- To review current miRNA therapeutic techniques for cardiovascular disease.
- To evaluate the advantages, risks, and challenges associated with miRNA modulation therapies.
- To highlight the potential of miRNA modulators in treating ischemic heart disease.
Main Methods:
- Review of existing literature on miRNA dysregulation in atherosclerosis.
- Summary of various miRNA therapeutic strategies including antimiRs, mimics, sponges, masking, and erasers.
- Analysis of the therapeutic potential and limitations of each technique.
Main Results:
- miRNA dysregulation is a key factor in the pathogenesis of atherosclerosis.
- Several miRNA modulation techniques exist, each with unique benefits and drawbacks.
- Targeting specific miRNAs can potentially reverse or halt atherosclerotic processes.
Conclusions:
- miRNA modulation represents a novel therapeutic avenue for cardiovascular diseases.
- Understanding the risks and challenges is crucial for the clinical translation of miRNA therapies.
- Further research into miRNA-based treatments could revolutionize the management of ischemic heart disease.
Abstract:
Cardiovascular disease (CVD) is the most important cause of death and illness in the western world. Atherosclerosis constitutes the single most important contributor to CVD. miRNAs are small ribonucleic acids (RNAs) that negatively regulate gene expression on the post-transcriptional level by inhibiting mRNA translation or promoting mRNA degradation. Several studies demonstrated that miRNAs dysregulation have a key role in the disease process and, focusing on atherosclerotic disease, in every step of plaque formation and destabilization. These data suggest a possible therapeutic application of miRNA modulation, in particular dysregulated miRNAs can be modulated in disease process antagonizing miRNAs up-regulated and increasing miRNAs down-regulated. In this review we summarize the miRNA therapeutic techniques (antimiR, mimics, sponges, masking, and erasers) underlining their therapeutic advantages and evaluating their risks and challenges. In particular, the use of miRNA modulators as a therapeutic approach opens a novel and fascinating area of intervention in the therapy of ischemic heart disease.

Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and narrowing...
