The mRNA levels of lncRNA, including KCNQ1OT1 and ATP1B3-AS1, were downregulated in the high-risk group, whereas protective m6A-related lncRNAs, including PTOV1-AS2, AC116914.2, EHMT2-AS1, AL136295.2, AC104564.3, and AC073534.2, were expressed at low levels in the high-risk group in both the bladder cancer training and test cohorts (Figures 7(e) and 7(f)). Here, PTOV1 is linked to urinary bladder carcinoma.
