As a result, seven proteins were chosen for further evaluation in the urine of PCa patients and controls: alpha-2-glycoprotein 1, zinc binding (AZGP1), malate dehydrogenase 2 (MDH2), fatty acid binding protein 5, epidermal (FABP5), enolase 1 (ENO1), glutathione S transferase Pi (GSTP1), cytovillin/ezrin (EZR), and glutathione S-transferase Mu 2 (GSTM2). The gene discussed is EZR; the disease is posterior cortical atrophy.
