Abstract:
Peripheral arterial disease (PAD) involves a general vascular problem of diffuse atherosclerosis. The key pathological process is characterized by the aberrant proliferation of vascular smooth muscle cells and the formation of neointimal lesions. The molecular mechanisms involved in the regulation of the occurrence and development of PAD remain unclear. microRNAs (miRNAs) are highly conserved 20-25 nt-long non-coding RNAs that negatively regulate gene expression. Recent evidence has demonstrated that specific miRNAs are involved in the pathological processes of PAD, and these miRNAs are found to be critical modulators of vascular cell functions, including cell differentiation, contraction, migration, proliferation and apoptosis. This review summarizes findings of studies regarding the roles of specific miRNAs in PAD.
Insights
Peripheral arterial disease (PAD) is linked to atherosclerosis and neointimal lesions. This review explores how microRNAs (miRNAs) regulate vascular cell functions and their role in PAD development.
Area of Science:
- Vascular Biology
- Molecular Medicine
- Genetics
Background:
- Peripheral arterial disease (PAD) is a manifestation of systemic atherosclerosis, characterized by neointimal lesion formation due to aberrant vascular smooth muscle cell proliferation.
- The precise molecular mechanisms governing PAD pathogenesis are not fully elucidated.
- MicroRNAs (miRNAs), small non-coding RNAs, are emerging as key regulators of gene expression.
Purpose of the Study:
- To review and summarize the current understanding of specific microRNAs (miRNAs) involved in the pathological processes of peripheral arterial disease (PAD).
- To highlight the critical roles of miRNAs in modulating vascular cell functions relevant to PAD.
Main Methods:
- Literature review of studies investigating the role of miRNAs in peripheral arterial disease (PAD).
- Analysis of findings on miRNA regulation of vascular smooth muscle cell proliferation, migration, differentiation, apoptosis, and contraction.
Main Results:
- Specific miRNAs have been identified as critical modulators in the development of PAD.
- These miRNAs influence key vascular cell functions, including proliferation and apoptosis, contributing to neointimal lesion formation.
- miRNAs represent a significant regulatory layer in the molecular pathology of PAD.
Conclusions:
- MicroRNAs play a crucial role in the molecular mechanisms underlying peripheral arterial disease (PAD).
- Understanding miRNA involvement offers potential therapeutic targets for PAD treatment.
- Further research into miRNA-mediated pathways is essential for advancing PAD management.
