microRNAs in Cerebrovascular Disease

Area of Science:

• Neuroscience
• Genetics
• Cardiovascular Medicine

Background:

• Cardiovascular diseases, particularly cerebrovascular diseases like stroke, are leading causes of disability and mortality.
• Effective primary and secondary prevention and treatment strategies are urgently needed.
• MicroRNAs (miRNAs), crucial post-transcriptional gene regulators, are implicated in the pathophysiology of cerebrovascular diseases.

Purpose of the Study:

• To summarize current knowledge on the epidemiology, etiology, and clinical manifestations of key cerebrovascular diseases.
• To review the involvement of specific miRNAs in the pathophysiology of these conditions.
• To explore the potential of miRNAs as diagnostic and therapeutic tools in clinical practice.

Main Methods:

• Review of existing literature on cerebrovascular diseases and miRNA involvement.
• Analysis of miRNA profiling and expression dynamics in animal and human studies.
• Focus on specific miRNAs implicated in carotid atherosclerosis, acute stroke, arteriovenous malformations, and intracranial aneurysms.

Main Results:

• Specific miRNAs (e.g., miR-126, miR-155, miR-145, miR-21, miR-29, miR-124) are involved in carotid atherosclerosis progression and stability.
• miRNA profiling reveals dynamic expression patterns in acute stroke across brain tissue and extracellular fluids.
• Certain miRNAs (e.g., miR-21, miR-26, miR-29, miR-143/145) show relevance in arteriovenous malformations and intracranial aneurysms.

Conclusions:

• MicroRNAs play significant roles in the pathophysiology of various cerebrovascular diseases.
• Understanding these miRNA roles is essential for developing novel diagnostic markers and therapeutic interventions.
• miRNAs hold promise as valuable tools for managing cerebrovascular disease burden.
