MALAT1 and posterior cortical atrophy: In our study, real-time PCR was employed at first to validate as PCa biomarkers 5 long RNAs (MALAT1, PCA3, PCAT18, KLK3, and TP53COR1) and 8 miRNAs (miR-27b-3p, miR-30a-3p, miR-30a-5p, miR-30b-5p, miR-30c-5p, miR-107, miR-125b-5p, and miR-574-3p) that were reported to be differentially expressed in different biofluids and EVs from PCa patients.
