Xu Z etal. (2019) determined that lncRNA HCG18/miR-34c-5p/NOTCH1network can regulate the proliferation and migration of bladder cancer cells. Ofnote, Wang Y et al. (2019)discovered that miR-34c-5p, FAM83A, FLJ26245 and KCNQ1OT1 are closely correlatedwith the survival rates of LADC patients. The gene discussed is KCNQ1OT1; the disease is urinary bladder cancer.
