Abstract:
MicroRNAs (miRNAs) are an emerging class of highly conserved, non-coding small RNAs that regulate gene expression on the post-transcriptional level by inhibiting the translation of protein from mRNA or by promoting the degradation of mRNA. The involvement of miRNAs in the regulation of lipid metabolism, inflammatory response, cell cycle progression and proliferation, oxidative stress, platelet activation, endothelial function, angiogenesis and plaque formation and rapture indicates important roles in the initiation and progression of atherosclerosis. In the light of this evidence we will review the role of miRNAs in atherosclerosis.
Insights
MicroRNAs (miRNAs) regulate gene expression and are involved in key processes like lipid metabolism and inflammation. This review explores the critical roles of miRNAs in the development and progression of atherosclerosis.
Area of Science:
- Molecular Biology
- Genetics
- Cardiovascular Research
Background:
- MicroRNAs (miRNAs) are small, non-coding RNAs regulating gene expression post-transcriptionally.
- They influence mRNA translation or degradation, impacting cellular functions.
- miRNAs are implicated in various biological processes relevant to atherosclerosis.
Purpose of the Study:
- To review the multifaceted roles of miRNAs in atherosclerosis.
- To highlight miRNA involvement in lipid metabolism, inflammation, and plaque development.
- To consolidate current understanding of miRNA function in cardiovascular disease.
Main Methods:
- Literature review of scientific publications.
- Analysis of studies investigating miRNA involvement in atherosclerosis.
- Synthesis of evidence on miRNA regulatory mechanisms.
Main Results:
- miRNAs significantly regulate lipid metabolism and inflammatory responses.
- They play crucial roles in cell cycle, proliferation, and oxidative stress.
- miRNA involvement is evident in endothelial function, angiogenesis, and plaque rupture.
Conclusions:
- miRNAs are key regulators in the initiation and progression of atherosclerosis.
- Targeting specific miRNAs presents potential therapeutic strategies for atherosclerosis.
- Further research is warranted to fully elucidate miRNA functions in cardiovascular health.
