Table 1. PCAT18-associated expression signature (PES) in prostate cancer samples.

Genes positively associated with PCAT18 (SAM analysis Q<0.5%) were uploaded in the Oncomine databases (thresholds: p<E-4, odds ratio>2). The first column indicates the queried Oncomine concept. The second column (“Studies”) shows the number of independent studies showing up- or down-regulation of PES for a specific concept. Oncomine™ (Compendia Bioscience, Ann Arbor, MI) was used for analysis.

Concept	Studies (Up/Down)	P value	Odds Ratio	Total Samples
PCa vs. Normal	16/0	3.1E-116-1.7E-6	2.4-13.4	928
PCa vs. Other Neoplasms	4/0	3.1E-51-6.9E-7	2.5-6.8	3195
Metastatic vs. Primary PCa	2/0	6.6E-8-2.3 E-5	2.9	27
