N-cadherin protein expressions in tumor tissue decreased significantly in the PCa+Docetaxel, PCa+LDH-A inhibitor, and PCa+LDH-A inhibitor + Docetaxel groups compared to the PCa group (p < 0.01, p < 0.05 and p < 0.01 respectively). The gene discussed is LDHA; the disease is posterior cortical atrophy.
