GENECHASER

With more than 200,000 microarray studies in public repositories, such as the NCBI Gene Expression Omnibus, we now have information on the expression levels of essentially all genes in the genome, across many tested biological conditions, such as diseases, drug responses, individuals, and more.

GENECHASER is a gene-specific search tool across all of these experimental conditions. Give us a gene symbol, or Entrez Gene ID, and we will find all experimental conditions where that gene is significantly changed in expression level. You can see these results in a special graphical view.

You can search for a gene in a single species, or across all available species. You can also search for conditions associated with significant simultaneous changes in multiple genes.
