Mounting evidence has demonstrated that epigenetic regulation of lncRNAs plays important roles in human cancer progression, and may hold the key to developing novel molecular target for cancer treatment.10, 11, 12 In the present study, we presented new data, showing lncRNA NORAD is upregulated in human EOC and inhibiting NORAD could yield tumor‐suppressing functions in EOC cells through endogenously competition against hsa‐miR‐155‐5p. The gene discussed is NORAD; the disease is cancer.
