In this high-throughput sequencing era, a tremendous amount of RNA-seq data is accumulating, and full utilization of publicly available miRNA data is an important challenge. Since its launch in 2014, piRBase has integrated 264 data sets from 21 organisms, and the number of collected piRNAs has reached 173 million. Background: MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression at the post-transcriptional level in eukaryotes. hsa-mir-132 is associated with one or more human diseases in the Human microRNA Disease Database. The remaining assays are in silico-validated using a comprehensive design algorithm with stringent assay performance criteria that ensures high-quality, species-specific, LNA. Background In plants, microRNAs (miRNAs) are pivotal regulators of plant development and stress responses. miRDB is an online database for miRNA target prediction and functional annotations. Information on the version number of miRBase is also available in the History of the downloaded sequence list, and when using this for annotation, the annotated samples will also include this information in their History (). To date, over 2000 human miRNAs have been reported in miRBase []. By miRNA identifier or keyword Enter a miRNA accession, name or keyword: Search.
