Overexpression of PRL-3 in prostate cancer tissue samples compared to normal tissue from the same samples. A total of 156 samples from radical prostatectomies were divided in groups based on Gleason score (GS), N (normal tissue, 40 samples), low risk (GS ≤ 6, 38 samples), medium risk (GS = 7, 42 samples) and high risk (GS ≥ 8, 36 samples). The groups were analyzed with Illumina gene expression microarray. The panels represent four different PRL-3 probes. For all Gleason groups there was a significant difference in gene expression compared with the normal group. Asterisks indicates P ≤ 0.05, Two asterisks indicates P ≤ 0.01 and four asterisks indicates P ≤ 0.0001
