KCNQ1OT1 and cancer: Further studies aimed at identification of KCNQ1OT1 lncRNA-targeted genes and the factors that maintain and regulate KCNQ1OT1 lncRNA-coated territory will be necessary in order to clarify the significance of the regulation of the extent of KCNQ1OT1 lncRNA-coated territory through an oncogenic signaling pathway such as Wnt/β-catenin in cancer development.
