As demonstrated in Fig. 1A, the results of 192 pathological sections confirmed the cytoplasmic localization of SLC4A4 and indicated that the expression of SLC4A4 in PCa tissues was distinctly higher than that in normal prostate tissues (P < 0.001; Table 1), which can be used for follow-up statistical analysis of clinicopathological data. Here, SLC4A4 is linked to posterior cortical atrophy.
