Identification of hsa ‐mir‐34a, hsa‐mir‐124, and hsa‐mir‐204 as signatures for cataract

This study aims to explore the key miRNAs underlying the pathogenesis of cataract and find prevention and treatment methods. First, six representative cataract miRNA datasets are selected and the key miRNAs are determined. The target genes of these key miRNAs are predicted using the TargetS can software, and then, the functional enrichment and transcription factor binding analysis of these target genes are completed, respectively. Three signature miRNAs associated with cataract are finally identified. Among them, hsa‐mir‐34a seems to be significantly upregulated, while hsa‐mir‐ 124 and hsa‐mir‐204 are significantly downregulated. The target genes of the signature miRNAs are mainly enriched in hsa04015:Rap1 signaling pathway, hsa04142:lysosome, and hsa04360:axon guidance, indicating that these pathways may be the crucial metabolic pathways. To summarize, three key miRNA s related to cataract pathogenesis are identified, and the corresponding target genes and transcription factors are also analyzed. Moreover, the potential functions of the target genes are revealed. The results of this study may contribute to the targeted therapy of cataract through miRNAs.
