NDRG1 and posterior cortical atrophy: Androgens regulated the expression of different ER stress associated genes in PCa, including N-myc downstream-regulated gene 1 protein (NDRG1), protein disulfide isomerase-related protein (PDIR/PDIA5), homocysteine-responsive ER resident ubiquitin-like domain member 1 protein (HERPUD), and oxygen-regulated protein 150 (ORP150) [71].
