MNX1-AS1 regulates the expression of RAB1A in bladder tumor cells by competitively binding with miR-218-5p, thereby promoting the proliferation, migration, invasion, and epithelial-mesenchymal transition of bladder tumor cells, which contributes to the growth and metastasis of bladder cancer cells (Wang et al., 2020). The gene discussed is RAB1A; the disease is urinary bladder cancer.
