PSMA in rat dorsal root ganglia shows an enzymatic activity of 9.9 ± 1.7 pmol NAAG/min/mg [20], while in the superior cervical ganglion PSMA activity (26.5 ± 0.2 pmol NAAG/min/mg) [20] is virtually equal to that of LNCaP cells (29.0 ± 2.6 pmol NAAG/min/mg) [22], which are broadly used for PCa xenograft models. This evidence concerns the gene FOLH1 and posterior cortical atrophy.
