Last Database Update
MTB 1.7.0
Welcome to the Mouse Tumor Biology (MTB) Database

The Mouse Tumor Biology (MTB) Database supports the use of the mouse as a model system of hereditary cancer by providing electronic access to:

  • Information on endogenous spontaneous and induced tumors in mice, including tumor frequency & latency data,
  • Information on genetically defined mice (inbred, hybrid, mutant, and genetically engineered strains of mice) in which tumors arise,
  • Information on genetic factors associated with tumor susceptibility in mice and somatic genetic-mutations observed in the tumors,
  • Tumor pathology reports and images,
  • References, supporting MTB data
  • Links to other online resources for cancer

What's new in MTB?


  • September
    • MTB now holds over 70,000 tumor frequency records.
  • August
    • 50 Lymphoma and Leukemia Histology and Immunohistochemistry Whole Slide Scans with Detailed Pathology Annotations are now available on the Lymphoma Pathology Page.
  • July
    • The JAX Patient Derived Xenograft (PDX) Resource has information on over 440 PDX models.


  • November
    • MTB is presenting a poster at Beyond the Genome: Cancer Genomics, October 8-10, 2014, Boston, MA.
  • October
    • MTB is highlighted in a publication in Experimental Dermatology:
      Begley DA, Krupke DM, Neuhauser SB, Richardson JE, Schofield PN, Bult CJ, Eppig JT, Sundberg JP. 2014. Identifying mouse models for skin cancer using the Mouse Tumor Biology Database. Exp Dermatol. 2014 Oct; 23(10):761-3. PMID:25040013
  • April
    • MTB now holds over 60,000 tumor frequency records.


  • October
    • Researchers can now search MTB for xenograft models and associated data (histology and genomics) contained in the JAX Patient Derived Xenograft (PDX) Resource.


  • December
    • In 2012 MTB presented at the following:
       11th Annual Workshop on the Pathology of Mouse Models for Human Disease,
       Biocuration 2012,
       Mechanisms & Models of Cancer,
       Model Organisms to Human Biology - Cancer Genetics,
       Second Annual Mutant Mouse Necropsy Workshop.
  • September
    • MTB now holds over 50,000 tumor frequency records.
  • July
    • MTB was highlighted in Chapter 3.1 of 'The Laboratory Mouse, 2nd Edition'.
  • June
    • The cancer QTL viewer has been updated. A number of new features have been added including querying and importing features from MGI, importing and exporting features via GFF formatted files.


  • October
    • MTB now holds over 5,000 images, including histopathology, SKY CGH and FISH images.
  • February
    • The cancer QTL viewer has been updated. The improved user interface is the first step in providing more features and enhancements to the viewer.
    • The immunohistochemistry links have been updated and expanded.


  • November
    • Now you can search for cancer-related mouse gene expression data sets that are in NCBI's Gene Expression Omnibus (GEO) archives with the new Gene Expression Data Set Search Form. Users can search by organ, tumor classification, mouse strain or expression assay platform to find relevant gene expression data sets. Search results provide links to external gene expression data as well as MTB tumor frequency records and strain details.
  • October
    • MTB now holds over 40,000 tumor frequency records
  • April
    • You can now search MTB using Human Gene Symbols. Entering all or part of one or more human gene symbols or Entrez Gene Ids into the new Human Gene Search Form returns orthologous mouse symbols and any genetic data attached to these symbols. These data include alleles and transgenes in mouse strains and tumor specific mutations associated with these symbols. Links allow users to view detailed tumor frequency, strain and pathology data. The search page also includes collections of cancer specific human genes reported by various sources which can be used for orthology searches.
  • January
    • The Tumor Frequency Grid, MTB's interactive graphic display of tumor frequencies, displays as a matrix the strain in which tumors were assessed and the organ systems in which tumors were observed. Our newest enhancements to the Grid allow the user to customize the Grid contents on both axes. Thus, the user can select specific strains or strain families and specific organs or organ systems to obtain a Grid showing any desired combination of strains/families and organs/systems. Try these new enhancements here:


  • September
    • MTB was well represented at the 8th Annual Workshop on the Pathology of Mouse Models for Human Disease, September 11-17, 2009 in Bar Harbor, ME. Participation included a platform presentation by Dr. J.P. Sundberg, entitled "Strain specific diseases in mice: Utilizing online resources" and a tutorial / workshop on using MTB and a poster presentation by Dr. D.A. Begley.
  • March
    • MTB announces the addition of a cancer Quantitative Trait Loci (QTL) Viewer. The Viewer allows users to see an overview of all cancer QTLs identified in the mouse or to display QTLs associated with cancer of particular organs. The user can "drill down" to see details of a particular chromosome or QTL, obtain lists of candidate genes in regions of interest, and link out to related data at MGI or the UCSC Genome Browser.


  • December
    • MTB has begun adding cytogenetic assay image data to the image archives. This includes images from spectral karyotyping (SKY), comparative genome hybridization (CGH) and fluorescence in-situ hybridization (FISH) assays of mouse tumors. Users may now refine their genetics searches to only those cytogenetic data associated with an image. Links to cytogenetics image data are also provided in the Genetics section of the Tumor Frequency Details pages (where applicable) (For an example see:
  • October
    • The Genetics Search Form has been updated and streamlined. Users can search for germline genetic, tumor somatic genetic and, now, cytogenetic data.
  • January
    • MTB now holds over 30,000 tumor frequency records!


  • October
    • MTB announces the incorporation of tumor pathology data and images from the Shock/Ellison Aging Study conducted at the Jackson Aging Center. These images are from young, middle-aged and old mice (male and female) from each of 32 strains. Additional data from this on-going study will be added as it is produced.
  • August
    • MTB is presenting a poster at the Mechanisms & Models of Cancer Meeting, Aug 8 - 12, 2007 at the Salk Institute, La Jolla, California. Stop by and see us!
