Commun. 471, 454-458 (2016) COMMENT Extraction of total RNA from the brain tissues and the subsequent isolation of a small RNA fraction of 18-50 nucleotides were carried out by using an RNAiso (TAKARA BIO) and a Small RNA Gel Extraction Kit (TAKARA BIO), respectively. Small RNA libraries were constructed from the small RNA fraction using a Small RNA Cloning Kit (TAKARA BIO), and then subjected to high-throughput pyrosequencing on a Genome Sequencer FLX System (Roche). After removing sequence artifacts generated in the library construction step, all the significant reads were mapped to the mm9 assembly of the mouse genome and to sequences with known function. The genome assembly and some functional annotation are available from the genome browser at the UCSC (http://genome.ucsc.edu). To identify small RNAs corresponding to microRNA (miRNA), Piwi-interacting RNA (piRNA), rRNA, tRNA, small nuclear RNA (snRNA), small nucleolar RNA (snoRNA), small cytoplasmic RNA (scRNA), miscellaneous RNA (miscRNA) and mRNA based on sequence similarity, we downloaded the sequences of these known RNAs from the following databases: miRNA, miR Base (ftp:// ftp.ac.uk/mirbase/sequences/13.0/mature.fa.gz, ftp://ftp.ac.uk/mirbase/sequences/13.0/hairpin.fa.gz); piRNA, NCBI Entrez Nucleotide Database (http://www.ncbi.nlm.nih.gov/entrez/ query.fcgi?db=Nucleotide); mRNA, NCBI Reference Sequences (ftp://ftp.ncbi.nih.gov); other RNAs, Ensembl Genome Browser (ftp://ftp.ensembl.org/pub/release55). Then, BLASTN search was performed using our RNA sequences as queries and the downloaded sequences as a database. Since the sequences in the databases could not cover all of our RNA species, we aligned the query sequences with the database sequences using a 90% match criterion including gaps. If a small RNA had more than one annotation, we used the following order of priority: miRNA, piRNA, rRNA, tRNA, snRNA, snoRNA, scRNA, miscRNA and mRNA. Any un-annotated reads were classified as "match genome" or "no-match genome" when they were mapped to the mouse genome with a perfect or imperfect match, respectively.
