- R Pearson correlation coefficients for co-expression of gene pairs PSMD14/RAN and PSMD14/XPO1 in 13 tumour types (CA) and in their respective normal tissue counterparts (N). Higher values in the comparison are in darker blue and lower values in lighter blue. Differences of R values ≥ 0.5 between CA and N are highlighted in yellow and differences of R values ≥ 0.3 are highlighted in orange
