Moreover, ERG protein expression, consistent with its mRNA expression, was also decreased in all PCa lines transfect with miR-NC+siR-E-834 or miR-AO+siR-E-834 respectively, while increasing in both DU145 and LNCaP cells with miR-AO+siR-E-NC (Figure 5). The gene discussed is ERG; the disease is posterior cortical atrophy.
