While microRNAs (miR) and other types of non-coding RNAs, such as metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), imprinted maternally expressed transcript (H19), and long intergenic noncoding RNA Up-regulated in bladder cancer 1 (linc-UBC1), greatly contribute to the biological function of bladder cancer (BlCa) and are being increasingly explored to improve the clinical care of patients, the biological importance of these UCRs in the pathogenesis of BlCa has not yet been investigated, and their function is currently unknown. The gene discussed is MALAT1; the disease is urinary bladder carcinoma.
