Figure 1: Genes encoding proteasome catalytic subunits are overexpressed in several cancer types.

Boxplots of log10 [1000 × RPKM + 1] values for genes encoding proteasome catalytic subunits were drawn for the indicated cancer types. CP genes (on the left) are PSMB5, PSMB6 and PSMB7, whereas IP genes (on the right) are PSMB8, PSMB9 and PSMB10. Red boxplots represent cancer samples and blue boxplots represent normal samples (when data are available). Differences in mean values between groups were determined by two-tailed unpaired Student’s t-tests. *Indicates p < 0.05. R.C: Renal Cell; R.P: Renal Papillary; AML: Acute Myeloid Leukemia; A.D: Adenocarcinoma; S.C: Squamous Cell.
