Long non-coding RNAs expression profile and functional analysis of acute ischemic stroke

Area of Science:

• Genomics
• Molecular Biology
• Neuroscience

Background:

• Long non-coding RNAs (lncRNAs) are implicated in various diseases.
• The role of lncRNAs in acute ischemic stroke (AIS) is not well understood.

Purpose of the Study:

• To investigate the differential expression and function of lncRNAs in AIS.
• To identify potential diagnostic and therapeutic biomarkers for AIS.

Main Methods:

• High-throughput sequencing to analyze lncRNA expression profiles in AIS patients.
• Gene Ontology (GO) and pathway analyses to determine gene function.
• lncRNA-mRNA correlation network construction and quantitative RT-PCR (qRT-PCR) validation.

Main Results:

• Identified 44,578 aberrantly expressed lncRNAs in AIS, including 228 upregulated and 16 downregulated.
• Validated the differential expression of six specific lncRNAs (ENSG00000269900, ENSG00000196559, ENSG00000202198, ENSG00000226482, ENSG00000260539, XLOC_013994_2).
• Suggests upregulated lncRNA ENSG00000226482 may activate the adipocytokine signaling pathway, contributing to AIS.

Conclusions:

• lncRNA expression is significantly altered in acute ischemic stroke.
• Identified potential lncRNA biomarkers for AIS diagnosis and therapy.
• Provides novel insights into the molecular mechanisms underlying AIS.
