Zhu et al. identified hsa-miR-125b (namely hsa-miR-125b-5p) as an independent factor indicating castration resistant in PCa (Zhu et al., 2015), and this miRNA could improve the prediction of PCa status on the basis of serum PSA screening (Roberts et al., 2015). The gene discussed is KLK3; the disease is posterior cortical atrophy.
