KDM4A and posterior cortical atrophy: As can be seen in Table 1 and Supplementary Table 1, KDM4A-AS1 level was only linked with PCa patients’ disease status (HSPC or CRPC, P value = 0.0364), KDM4A-AS1 expression was closely related to DFS time in CRPC patients (P value = 0.0119) and was independent with patients’ age, smoke history, alcohol history, and Gleason score, indicating a specific potential role of KDM4A-AS1 in CRPC.
