RMRP and urinary bladder cancer: Like lncRNA-RMRP, which promotes bladder cancer proliferation, migration, and invasion through miR-206(Cao et al. 2019), Peng et al. found that lncRNA PSMA3-AS1 promotes colorectal cancer cell migration and invasion by regulating miR-4429(Peng et al. 2020), and Luo et al. found that lncRNA DANCR promotes pancreatic cancer proliferation and metastasis by regulating miRNA-33b (Luo et al. 2020).
