NF-κB upregulated circNOLC1 regulates PCa progression through the miR-647/PAQR4 axis [15], circSMARCA5 facilitates PCa cellular behaviors through the miR-181b-5p/miR-17-3p-TIMP3 axis [16], and circGNG4 promoted PCa progression through modulating the miR-223/EYA3/c-myc pathway [17]. Here, MYC is linked to posterior cortical atrophy.
