To evaluate the associations of miR-193a-5p-TP73 and miR-188-5p-UBE2I expression with various clinicopathological features of PCa patients, the optimal cutoff points of miR-193a-5p, TP73, miR-188-5p and UBE2I expression were screened. The gene discussed is UBE2I; the disease is posterior cortical atrophy.
