In addition, we revealed that a combination of four PCa biomarkers, UDP-N-acetyl-α-D-galactosamine transferase (GalNAc-T3), PSMA, Hepsin and DD3/PCA3 represented a powerful new approach for detecting all PCa cells by molecular profiling (Landers et al, 2005). The gene discussed is PCA3; the disease is posterior cortical atrophy.
