NEAT1 and posterior cortical atrophy: Although NEAT1 level exhibits no obvious difference in BPH and HC tissues (P>0.05, Figure 1A), it is clearly showed that the expression level of NEAT1 is significantly up-regulated in PCa tissues, compared with BPH (P<0.0001) and HC tissues (P<0.0001, with average 6.42-fold increase compared with matched healthy tissues, Figure 1B).
