| Outline of Final Research Achievements |
In this study, to identify circulating exosomal miRNA biomarkers for predicting carcass traits and meat quality characteristics of Japanese Black cattle by bioinformatics analysis, we first compared exosomal miRNA expression profiles of serum between low and high merit steers in main carcass traits. We then inferred the involvement of the lower- or higher-expressed exosomal miRNAs in metabolic pathways by computational searches of existing public databases (miRDB, and PANTHER). As a result, our study suggests the possibility of at least eight identified exosomal miRNAs as biomarker candidates for predicting carcass traits and meat quality characteristics during fattening of Japanese Black cattle.
