How do I find references that report expression data for a gene at a specific age?
Overview
You can use the Gene Expression Literature Query Form to search for references on gene expression during development using the genes and ages analyzed (and the assay types used) in the references. Other fields on the form allow you to query for bibliographic information or specific words in the title or abstract.
Accessing the Genes Expression Literature Query Form
On most MGI pages, you can access the Genes Expression Literature Query Form from the Search menu as shown in the image at right.

For this tutorial, open the Gene Expression Literature Query Form in a new window. Scroll down this page for further instructions.

Example 1. Finding literature assaying Fgf8 expression at 10.5 days post-conception
  1. Type fgf8 into the Gene Symbol/Name text box.

  2. Select 10.5 from the Age pick list.

  3. Click Search.

  1. The search results list references that examined Fgf8 expression at embryonic day 10.5 (E10.5) as well as the assay types used in these studies.

  2. The Summary by Age and Assay table at the top of the page groups the references by developmental stage analyzed and assay type used. You can click a numerical link to retrieve a list of these references.

  3. Scroll down the page. The Summary by Gene and Reference table lists references that analyze Fgf8 expression. The numerical links indicate the number of results for each reference. Numerical links that are followed by an asterisk indicate that detailed assay results from that reference have been entered into the database. You can click a numerical link to view a table that summarizes which ages were analyzed and which assay types were used to examine expression of that gene in that reference.
