Subsequent qRT-PCR experiments on PBMC samples provided further evidence of the potential of PRC1 and UBA52 as biomarkers for the metastatic stage of PCa, RCC1 as a biomarker for both BR and metastatic stages, and indicated the prognostic value of elevated miR-124-3p and downregulated miR-133a-3p in the BR stage. Here, PRC1 is linked to posterior cortical atrophy.
