Overrepresentation of PANTHER protein classes and Gene Ontology annotations among differentially expressed proteins in human prostate tumors.

	Fold Enrichment	Q-value
PANTHER Protein Class
Chaperonin	> 5	2.43E-03
Dehydrogenase	> 5	4.59E-03
Oxidoreductase	> 5	1.24E-02
GO Molecular Function
Oxidoreductase activity	> 5	1.25E-02

Overrepresentation was determined by calculating the probability that the number of differentially expressed proteins belonging to a particular category is larger or smaller than what would be expected based on a reference human genome of 20,814 genes. Q-values have been adjusted using a Bonferroni correction.
