In breast tumors, Feng et al. (2018) showed that the expression of KCNQ1OT1 was much higher in cancerous breast tissues (n = 18) than in normal adjacent breast tissues and that the increase in KCNQ10T1 showed an association with the advanced tumor stage (III/IV) [45]. The gene discussed is KCNQ1OT1; the disease is neoplasm.
