Identification of corneal neovascularization-related long noncoding RNAs through microarray analysis

Area of Science:

• Ophthalmology
• Molecular Biology
• Genetics

Background:

• Corneal neovascularization (CN) is a significant cause of vision loss.
• The role of long noncoding RNAs (lncRNAs) in CN pathogenesis is not well understood.

Purpose of the Study:

• To investigate the role of lncRNAs in corneal neovascularization (CN).
• To identify potential therapeutic targets for CN.

Main Methods:

• Established a murine CN model.
• Performed lncRNA expression profiling and constructed a lncRNA/mRNA coexpression network.
• Conducted Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses.
• Validated lncRNA expression in clinical samples using real-time PCR.

Main Results:

• Identified 154 differentially expressed lncRNAs in vascularized corneas compared to normal corneas (60 downregulated, 94 upregulated).
• GO analysis revealed associations with extracellular region, DNA binding, and immune response.
• KEGG analysis highlighted "pathways in cancer" as the most enriched pathway.
• Specific lncRNAs (NR_033585 and lincRNA:chr8:129102060-129109035) were differentially expressed in CN.

Conclusions:

• This research offers new insights into the pathogenesis of CN.
• Dysregulated lncRNAs represent potential therapeutic targets for preventing and treating ocular vascular diseases.
