A study investigating the function of lncRNA KCNQ1OT1 in bladder cancer found that KCNQ1OT1 was significantly overexpressed in bladder cancer tissues and cell lines and that knockdown of KCNQ1OT1 resulted in repressed proliferation, migration, invasion, and enhanced apoptosis of bladder cancer cells. The gene discussed is KCNQ1OT1; the disease is urinary bladder carcinoma.
