PIK3CB and posterior cortical atrophy: In our previous studies, we have applied an correlation-based, integrative genomic approach to define a novel panel of reciprocal miRNA-mRNA pairings (miR-34a-5p/HIF1A, miR-34a-5p/PIK3CB, miR-34a-5p/IGFBP2, miR-99b-5p/MTOR, miR-96-5p/MAPKAPK2, miR-133a/MCL1, miR-513c/STAT1, miR-96/FOXO3A, miR-145/ITPR2, and miR-34a/PPP2R2A) as critical regulatory components involved in AA PCa disparities [14,15].
