Expression profile of long noncoding RNAs in post-stroke aphasia

Area of Science:

• Neuroscience
• Molecular Biology
• Genetics

Background:

• Post-stroke aphasia (PSA) significantly impacts stroke survivors' quality of life.
• The role of long noncoding RNAs (lncRNAs) in PSA pathogenesis is not well understood.
• Identifying biomarkers for PSA is crucial for diagnosis and treatment.

Purpose of the Study:

• To explore lncRNA expression profiles in post-stroke aphasia.
• To identify potential lncRNA biomarkers associated with PSA.
• To investigate the correlation between lncRNA expression and language deficits.

Main Methods:

• High-throughput RNA sequencing (RNA-seq) was used to analyze lncRNA expression profiles.
• Quantitative polymerase chain reaction (qPCR) validated key lncRNA findings.
• Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed.

Main Results:

• 797 differentially expressed lncRNAs were identified between PSA and stroke patients.
• LncRNA RP11-227G15.3 was found to be upregulated in PSA patients.
• A preliminary negative correlation between RP11-227G15.3 and oral spelling scores was observed.

Conclusions:

• LncRNA RP11-227G15.3 is a candidate biomarker for PSA.
• Further validation in larger cohorts is necessary to confirm its clinical utility.
• The preliminary association with oral spelling requires further investigation.
