USP13 and posterior cortical atrophy: Subsequently, the correlations between the expression of candidate LncRNAs and USP13 were evaluated, and LncRNAs that positively or negatively correlated to USP13 are documented in Fig. 10F and G. All LncRNAs were subjected to three categories: LncRNAs which positively correlated to USP13 and negatively correlated to miRNAs, LncRNAs which had predictive potentials for OS of PCa patients, and LncRNAs which were highly expressed in PCa tumors (Table 4).
