Considering this study’s focus on the role of peroxisomes in PCa pathogenesis, it is noteworthy that CAT, a key peroxisomal antioxidant enzyme known for efficiently scavenging excess H2O2, consistently showed higher expression levels in malignant prostate cells compared to non-malignant cells (Figure 6A,B). The gene discussed is PRDX5; the disease is posterior cortical atrophy.
