Long non‐coding RNAs have recently emerged as an important regulator on transcriptional and post‐transcriptional regulation of several diseases, including cancers.14, 15, 16 LncRNA NNT‐AS1 has been found to participate in the tumorigenesis of hepatocellular carcinoma, cervical cancer and colorectal cancer.17, 18, 19 In the pre‐experiments of our study, we found that the lncRNA NNT‐AS1 expression level was up‐regulated in GC tissue samples and cells. This evidence concerns the gene NNT and cervical carcinoma.
