Role of miR-181 Family Members in Stroke: Insights into Mechanisms and Therapeutic Potential.

Stroke is a major cause of mortality and long-term disability worldwide, making early diagnosis and effective treatment crucial for reducing its impact. In response to the limited efficacy of current treatments, alternative therapeutic strategies, such as novel biomarkers and therapies, are emerging to address this critical unmet medical need. MicroRNAs (miRNAs) are small, non-coding RNAs that regulate gene expression at the post-transcriptional level. Due to their dysregulation, they have been implicated in the onset and progression of various diseases. Recent research highlighted the important role of miR-181 family members in the context of stroke. Polymorphisms such as rs322931 in miR-181b are associated with increased stroke risk. miR-181 family members are aberrantly expressed and related to various aspects of stroke pathology, affecting inflammatory responses or neuronal survival. We provide a comprehensive overview of how alterations in miR-181 expression influence stroke mechanisms and their potential as therapeutic targets. [ABSTRACT FROM AUTHOR]
