TACSTD2 and posterior cortical atrophy: We also observed that, while TACSTD2 mRNA expression was positively correlated with the overall survival time (Spearman rho = 0.12, p = 0.31) (Figure 3D), GSE1 expression was inversely correlated (Spearman rho = −0.07, p = 0.55) in the pooled PCa data (Figure 3E).
