Recently, potential roles of miR-143 in ceRNA regulation were also noticed, and several other lncRNA–mRNA pairs have been reported in bladder cancer, including the PCAT6–miR-143-3p–PDIA6 axis [41], LINC00511–miR-143-3p–PCMT1 axis [42], SNHG1–miR-143-3p–EZH2 axis [43], MAFG–AS1–miR-143-3p–COX-2 axis [44], circ_0006332–miR-143–MYBL2 axis [45], FOXD2–AS1–miR-143–ABCC3 axis [46], and UCA1–miR-143–HMGB1 axis [47]. The gene discussed is PTGDR; the disease is urinary bladder cancer.
