We then analyzed the mRNA level of the 9 m6A-related prognostic lncRNAs in bladder cancer, which indicated the mRNA level of 8 m6A-related prognostic lncRNAs (PTOV1-AS2, AC116914.2, EHMT2-AS1, AC004148.1, AL136295.2, KCNQ1OT1, AC104564.3, and AC073534.2) was upregulated and the expression of 1 m6A-related prognostic lncRNA (ATP1B3-AS1) was decreased in BC tissues compared with their expression levels in bladder tissues (Figure 2(c)). Here, ATP1B3 is linked to urinary bladder carcinoma.
