A wide range of promising PCa biomarkers has been reported, including CpG hypermethylation of GSTP1 [7], TMPRSS2:ERG gene fusion [8], AMACR [9], sarcosine [10], and the long noncoding RNA urine biomarker prostate cancer gene 3 (PCA3) [11]. This evidence concerns the gene TMPRSS2 and posterior cortical atrophy.
