MicroRNA-Expression Profiling in Myopia: A Meta-Analysis and Systematic Review

Area of Science:

• Ophthalmology
• Genetics
• Molecular Biology

Background:

• Myopia (nearsightedness) is a prevalent global eye disorder.
• Emerging research highlights the involvement of microRNAs (miRNAs) in myopia development.

Approach:

• A meta-analysis synthesized data from seven independent miRNA-expression profiling studies on myopia.
• A vote-counting method identified consistently dysregulated miRNAs.
• Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology (GO) analyses explored affected pathways.

Key Points:

• Eighteen miRNAs showed consistent dysregulation across studies, with 13 upregulated and 5 downregulated in myopic tissues.
• Subgroup analyses examined differences between human and animal models, and various ocular tissues.
• KEGG analysis implicated extracellular matrix-receptor interaction pathway, while GO analysis highlighted cellular protein modification processes.

Conclusions:

• Several dysregulated miRNAs show potential as biomarkers for myopia.
• Further research is necessary to understand the precise biological roles of these miRNAs in myopia pathogenesis.
