Searching by biological condition
You can also search Expression Atlas by using the Biological condition search box on the homepage. This type of search helps you find genes that are expressed in a particular condition, e.g. lung carcinoma (Figure 14A). You can limit the results to a particular species by selecting a species from the drop-down menu (Figure 14B). Your search is expanded using the Experimental Factor Ontology (EFO), so that it will also return synonyms and child terms of lung carcinoma (Figure 14).

When searching by biological condition, you will see both baseline expression (Figure 15) and differential expression results (Figure 15). Just click on the title of any experiment in the:
- Baseline expression results (Figure 15) to see the corresponding baseline experiment page
- Differential expression results (Figure 15) to see the corresponding differential experiment page
