No significant differences in housekeeper expression (ALAS1, B2M, GAPDH, HPRT, RPLP2, TBP) were found between non-cancer (NC) and prostate cancer (PCa) samples in either fraction (False Discovery Rate (FDR) p < 0.05; edgeR; Figure 1B,D; Table S2). This evidence concerns the gene RPLP2 and posterior cortical atrophy.
