For that reason, the changes detected in the expression level of one isomer. マイクロRNA (miRNA) は、22塩基ほどの小さな核酸ですが、生命科学において非常に重要な役割を担っています。. MicroRNAs (miRNAs) are post-transcriptional regulators of gene expression in both animals and plants. Importing the miRBase data file;For the miRBase-based alignment search, we included additional SNP information in the miRNA library based on the updated miRNASNP database . miRBase is the primary online repository for all microRNA sequences and annotation. Unfortunately, miRBase annotates only one mature miRNA for a given miRNA locus, and often the most abundant isomiR present in the sample is not necessarily the one annotated in miRBase .
