Genes are shift workers—while some labor, others relax, waiting for their chance to join the action. The Gene Expression Database, hosted by the Jackson Laboratory in Bar Harbor, Maine, holds data on the activity of thousands of mouse genes, using information gleaned from the literature or submitted by researchers. The collection focuses on gene expression during development. You can pick a particular stage—from single-celled egg to postbirth pup—and determine what genes are working in particular structures, such as the heart or brain. Entries summarize the methods and gene activity measurements for each study and provide figures from the original paper.
