LncRNAs including FLVCR1‐AS1, HOXD‐AS1, MLK7‐AS1 and HOTAIR have been reported to promote ovarian cancer development through such mechanisms,8, 9, 10, 11 while some other lncRNAs, such as MAGI2‐AS3, showed a cancer‐suppressive role in ovarian cancer development.12 The gene discussed is HOTAIR; the disease is ovarian cancer.
