Long Noncoding RNAs in the Pathophysiology of Ischemic Stroke

Area of Science:

• Neuroscience
• Genomics
• Molecular Biology

Background:

• Ischemic stroke causes significant global mortality and disability.
• Noncoding RNAs, particularly long noncoding RNAs (lncRNAs), are increasingly recognized for their cellular functions.
• lncRNAs are implicated in the complex molecular mechanisms underlying stroke pathology.

Purpose of the Study:

• To review the current understanding of lncRNA roles in ischemic stroke.
• To summarize findings on aberrant lncRNA expression in stroke.
• To discuss the clinical relevance of lncRNAs in stroke risk and progression.

Main Methods:

• Literature review of experimental and clinical studies.
• Analysis of high-throughput gene expression data (RNA-seq, microarrays).
• Examination of genetic variations in lncRNA loci.

Main Results:

• Numerous lncRNAs show altered expression in the brain and blood post-stroke.
• lncRNA expression patterns are temporal and cell-type specific.
• Dysregulated lncRNAs influence detrimental and neuroprotective pathways in stroke.

Conclusions:

• lncRNAs are critical players in ischemic stroke pathophysiology.
• Differential lncRNA expression and genetic variations are associated with stroke.
• lncRNAs represent promising biomarkers and therapeutic targets for stroke.
