In addition, the Spearman Correlation analysis showed that the expression level of SOX7 protein in PCa tissues was significantly negative correlated with that of SOX9 protein (rs = -0.408, p < 0.001) and positive correlated with that of SOX10 protein (rs = 0.513, p < 0.001), respectively; the expression level of SOX9 protein was also significantly negative correlated with that of SOX10 protein (rs = -0.219, p = 0.008). This evidence concerns the gene SOX7 and posterior cortical atrophy.
