However, we observed that relative levels of DPP4 transcripts were lower in PCa patients with a high Gleason score (Figure 1B), advanced cT (Figure 1C), pathological T stages (Figure 1D) and lymph node (Figure 1E, left panel) or distal (Figure 1E, right panel) metastasis. This evidence concerns the gene DPP4 and posterior cortical atrophy.
