Differential Expressions of microRNAs and Transfer RNA-derived Small RNAs: Potential Targets of Choroidal Neovascularization.
Purpose: Choroidal neovascularization (CNV) is one of the major clinical characteristics of neovascular age-related macular degeneration (AMD). Small non-coding RNAs, such as microRNAs (miRNAs) and transfer RNA-derived small RNAs (tsRNAs) play key roles in diverse biological functions. The purpose of the study was to investigate the roles and possible functions of the miRNAs and tsRNAs in CNV. ⋯ GO analysis revealed that the altered target genes of the selected miRNAs most enriched in immune response, integral component of membrane and peptide binding, while the altered target genes of tsRNAs most enriched in regulation of immune system process, extracellular region, and core promoter binding. Moreover, KEGG pathway analysis demonstrated that altered target genes of miRNAs and tsRNAs most enriched in hematopoietic cell lineage and nucleotide-binding oligomerization domain (NOD)-like receptor signaling pathway, respectively. Conclusions: Our study identified differential expressions of miRNAs and tsRNAs in CNV model, and these altered miRNAs and tsRNAs might be novel potential targets in treating CNVs in patients with neovascular AMD.
