Interestingly, significant differences in gene expression between NPT and PCa were confirmed for CD44, KRT14 and WNT5A, but not for CAMK2N1 and TGFβ3. The results observed for CAMK2N1 might be explained by the low expression demonstrated by pT2a+b tumors, which is very similar to NPT, negatively impacting in the comparison PCa vs. NPT. Here, CAMK2N1 is linked to posterior cortical atrophy.
