- R Pearson correlation coefficients for select gene pairs within the set of proteasome genes (PSMA2, PSMB5, PSMD7, PSMD14) and between this subset of proteasome genes and the XPO1 gene in breast, prostate and endometrial cancer relative to normal breast, normal prostate and normal uterus. The higher R correlation factor in the comparison Normal vs Cancer is coloured in darker blue and the lower correlation factor in lighter blue. Differences of R values ≥ 0.50 are highlighted in yellow and differences ≥ 0.3 are highlighted in orange
