Therefore, deregulated miRNAs play important roles in the pathogenesis of diseases. Numerous studies are aimed at discovering biomarkers of diseases or determining miRNA functions by monitoring circulating miRNAs in various biological sources such as plasma and urine. However, the analysis of miRNA in such fluids presents problems related to accuracy and reproducibility because of their low levels in biological fluids. Therefore, better extraction kits and more sensitive detection systems have been developed for improved and reproducible analysis of circulating miRNAs. However, new extraction methods are also needed to improve the yield of miRNAs for their reliable analysis from biological fluids. The combination of yeast transfer RNA (tRNA) and glycogen as carrier molecules and incubation durations were optimized to maximize extraction efficiency. The extraction recovery using a combination of yeast tRNA and glycogen was approximately threefold more than that by using glycogen or yeast tRNA alone. In addition, reproducible and accurate analysis of miRNAs can be carried out after extraction using a combination of yeast tRNA and glycogen without an impact on plasma components.
