RPLP0 and posterior cortical atrophy: Secondly, (Figure 2b), when the presence of PCa was considered (patients with BPH vs. PCa), we again observed that the IRGs previously reported to be more stable (less variable) in the different analyses showed until this point (i.e., LRP10, PGK1, and RPLP0; data showed in Figure 1 and Figure 2a) did not exhibit differences in their expression levels (Figure 2a).
