  • High confidence miRNA set available for miRBase 21 July 3, 2014
    As mentioned previously, we briefly held off from releasing the set of “high confidence” miRNAs for miRBase 21, because of a last-gasp bug. Those data are now available, tagged with the label “high confidence” on the entry pages, and for download on the FTP site. The total number of miRNAs labelled “high confidence” has increased […]
  • miRBase 21 finally arrives June 26, 2014
    Apologies for the longer-than-usual wait. miRBase 21 is now available on the website, and all data available for download on the FTP site. As usual, the release notes describe the major changes. Of particular note this time, the Genome Reference Consortium have released a new human genome assembly, GRCh38. We have therefore remapped the human […]
  • miRBase 21 is coming …. June 16, 2014
    The release of miRBase 21 has taken much longer than we would have liked, but it’s nearly there now. We anticipate making the data available within the next week. Because of the time since the last release, it’s another hefty update, with over 4000 new hairpin sequences, and over 5000 new mature sequences. The new […]
  • High confidence microRNAs March 4, 2014
    I promised a while ago to provide more information about the miRBase website features associated with the new “high confidence” microRNA set, as described in our 2014 NAR paper. First, some background. Here is a figure showing the growth of the number of sequences deposited in miRBase, and the number of papers in Pubmed that […]
