RP11-89 together with 15 miRNAs and 62 target mRNAs associated with ferroptosis including ACSL4, PROM2, SLC7A11, TNFAIP3, GNAQ, SEMA6D, SEMA6A, ZEB1, and EIF4EBP1, were used to construct the lncRNA-miRNA-mRNA regulatory network, which suggested strong links between RP11-89 and ferroptosis in BLCA (Fig. 5B). This evidence concerns the gene PROM2 and bladder transitional cell carcinoma.
