RAC3 and posterior cortical atrophy: In the study, we compared the lncRNA expression profiles between PCa tissues and paracancerous tissues by using the high-throughput gene chip technology, then selected RP13-650J16.1 and TCONS_00023979 as the research objects according to a series of screening conditions (the chip results, adjacent coding genes information analysis) and previous reports of the involvement of receptor-associated coactivator 3 (RAC3) and promyelocytic leukemia (PML) in PCa [17–21].
