    • 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:

    • To improve the quality and utility of pathology images available, the Mouse Tumor Database (MTB) announces the incorporation of Zoomify technology ( into the web display of pathology images. Zoomify enables the representation of fast and interactive high-quality images on the web using HTML, JPEGs, and Flash. All of these programs are freely available. With Zoomify, users can change the perspective and magnification of an image dynamically. Users whose systems do not support Flash technology will still see pathology images in a static view. An example of a Zoomified image can be viewed at , Image ID: 1393.
  • August
    • The Tumor Frequency Grid has been enhanced and expanded. The strain family and organ entries have been made expandable to show frequency results for sub-strains of a strain family and sub-structures of an organ. Each results cell now has a rollover pop-up window that shows strain of origin, organ of origin, highest reported frequency and number of tumor frequency records. The grid is also now generated dynamically directly from the information in the database rather than being periodically updated.
  • July
    • The Mouse Tumor Biology Database (MTB) announces the release of the Advanced Search Form. This form enables researchers to perform complex queries combining search parameters from multiple basic search forms.
  • June

      The Pathology Submission Form allows researchers to:

      * Create Mouse Records including strain and genetics information.
      * Generate Tumor Diagnosis's specific for a Mouse Record.
      * Include detailed Pathology and Treatment descriptions in each Diagnosis.
      * Attach Images to a Diagnosis to complement the Pathology descriptions.
      * Have editorial access to any of their Data submitted to MTB.


  • May
    • Version 1.0 of the new Mouse Tumor Biology database is now publicly available. With this release MTB has been ported to Sybase as the database platform. This major infrastructure change provides a scalable foundation for future growth of the database and will enable us to develop new dynamic web-based user interfaces and provide programmatic accessible web services.

      Also with version 1.0, MTB's query interfaces and the results pages have been completely redesigned to match the look and feel of the other databases available through the Mouse Genome Informatics (MGI) web site. Look for additional features and new tools to continue to be released in the coming months...

      Currently MTB holds >16,000 tumor instances in >3,500 genetically defined mouse strains and >1,300 pathology images.
