Working example on how to query using the query page with screenshots. Please note that the "Official symbol" field no longer exists.

E.g. 1. Show all the genes, which are specific to tissue ?hematopoietic stem cell? in Organism "Homo sapiens". This example demonstrates a search of the Human TissueDistributionDB for genes having hematopoietic stem cell in the All Tissue field. The results can be viewed using the TissueSimple view.

  1. Query Form : In the AllTissues field text box( Fig. 1) enter the search term "hematopoietic stem cell" (SRS queries are case insensitive so it does not matter whether you use upper case, lower case or a mixture of the two).

  1. Results: The output which we can infer from the above basic example is
    1. In organism "Human", the number of genes which are specific to tissue "hematopoietic stem cell" are 8503* ( the number may vary with every new release).
    2. Using the BarchartView, the graphical representation of the percentage of expression of the given gene in the particular tissue is well visualized.
    3. TheTissueSimple View, we get a better view in a tabular form the gene symbols, description of the genes,along with the tissues in which they are expressed.
    4. Each entry gives a detailed description of the tissue distribution which can also be viewed using the Complete Entry SRS Predefined View.
    5. All the Levels of the tissues can also be visualized with Tissue Level2, Tissue Level3, Tissue Level4 and Tissue Level5 views.
    6. The Tissue summary View enables the user to see the summary of all the tissues in the given gene.
    7. Finally the querying can be extended to make more complex queries like for instance, check for a particular gene "KIST" whether it is present in Mouse ,Rat and Human. So we can select the 3 organisms, and submit, in the query page we can give "KIST" in GeneSymbol field and check the results. We see that the gene is absent in Mouse and Human, however in Rat it is expressed in 8 tissues and their percentage of expression using the different views.Several other forms of queries can also be performed.

      * the number of entries in the screen shots are mere representation for demonstration purpose, the actual number differs with each new database generation.

      **Note: the views at different levels 2,4,5 are similar to level 3 view
