Recently, increasing evidence suggested that KCNQ1OT1 played an important role in tumorigenesis and metastasis of different cancers.17 Dong et al revealed KCNQ1OT1 promoted NSCLC progression partly via sponging miR‐27b‐3p in order to target 3′‐untranslated region (3′‐UTR) of HSP90AA1 directly.18 The gene discussed is KCNQ1OT1; the disease is cancer.
