Identification and Characterization of MicroRNAs Expressed in the Mouse Eye

Abstract
Purpose. MicroRNAs (miRNAs) are a class of small, endogenous RNAs that negatively regulate gene expression post-transcriptionally by binding to target sites in the 3′ untranslated region (UTR) of messenger RNAs. Although they have been found to regulate developmental and physiological processes in several organs and tissues, their role in the eye transcriptome is completely unknown. This study was conducted to gain understanding of their eye-related function in mammals, by looking for miRNAs significantly expressed in the mouse eye by means of high-resolution expression analysis.
