Summary: We introduce ProfileChaser, a web server that allows for querying the Gene Expression Omnibus based on genome-wide patterns of differential expression. Using a novel, content-based approach, ProfileChaser retrieves expression profiles that match the differentially regulated transcriptional programs in a user-supplied experiment. This analysis identifies statistical links to similar expression experiments from the vast array of publicly available data on diseases, drugs, phenotypes and other experimental conditions.#R##N##R##N#Availability: http://profilechaser.stanford.edu#R##N##R##N#Contact: ude.drofnats@ettuba#R##N##R##N#Supplementary Information: Supplementary data are available at Bioinformatics online.
