  • Specimen & Data Collection

    Tohoku Medical Megabank Project collects biological specimens such as blood and urine, from a hundered and fifty thousand healthy Japanese participants with informed consent in Miyagi and Iwate prefectures. We also collect data from physiological examinations, physical measurements, medical and lifestyle information from the questionnaires, and MRI data of a part of the participants who offered their information at our sub-branches which are located in several community areas. The information is stored in the data storage system, and at the same time, the biological specimens are preserved in appropriate temperatures and in suitable conditions. The results of analysis of the biological specimens combined with the data and information above are combined to build an integrated database. We publicized a part of the data online. Scientists are able to use the data from the website. Biobank Office is certified by Alcumus ISOQAR to ISO 9001:2008 and Integrated Database Room, Sample & Information Room, and Biobank Office to ISO 27001:2013.

    *Customized LIMS (Laboratory Information Management System) based on LabVantage (LABVANTAGE Solutions) is used for specimen handling and inventory management. Specimens are aliquoted into storage tubes with 2D barcode. Freedom EVO robotic dispensers (TECAN) are used to aliquot specimens other than blood cell automatically.

    Integrative Japanese Genome Variation Database
    The data from its whole genome sequencing for 2,049 people, namely, data on single nucleotide polymorphism (SNP) frequencies. Our platform offers capabilities to perform SNP searches from the reference SNP ID number and Gene Symbol and to identify location information on the international human genome reference sequence.

    Japanese Reference Genome(JRG)
    ToMMo has constructed the Japanese reference genome v1 (JRGv1) with a long-read-type next generation sequencer, PacBio RSII (Pacific Biosciences), and the data is now available online.
    We repeatedly sequenced Japanese genomic DNA to obtain sequence information of 300-billion bases (as much as 100 times repeated sequencing of a genome). Then, we have applied a method of information science called de novo assembly, assembling the sequences from scratch with high accuracy. And finally we succeeded construction include 903 new insertion sequences (approximately a million bases in total) to the international human reference genome sequence GRCh38, and release of the present Japanese Reference Genome.
    Some sequences determined by long-read-type sequencer were not easily fit to the specific sites on GRCh38. We have collected such those sequences and released as decoyJRGv1. Now those were also be opened on the net.

    Japanese Multi Omics Reference Panel (jMorp)
    A database of metabolome and proteome data in plasma in ToMMo, is available online. Metabolome data were measured by proton NMR and LC-MS, and proteome data were obtained by nanoLC-MS. Metabolome data obtained from more than 1,000 adult people, and proteome data obtained from more than 500 adult people. We measured several thousand metabolites including the uncharacterized ones, and several hundred proteins until now. The data will be released after carefully checking each metabolite and protein in order. We also released correlation among metabolites and observed peptides of 256 abundant proteins.
