RNA interference‐mediated down‐regulation of UCA1 inhibited proliferation, migration and invasion of the bladder cancer cell, suggesting it can be a novel therapeutic target.83 Nevertheless, the clinical use of the therapy targeting these lncRNAs is still in its infancy, there are many obstructions need to be solved before the clinical popularization of the lncRNA‐based treatments. The gene discussed is UCA1; the disease is urinary bladder carcinoma.
