Long non‐coding RNA (lncRNA) dysfunction is related to a wide range of diseases, such as cancer, neurodegeneration, cardiovascular disease and neurasthenia.6 For example, overexpressed lncRNA NR_036575.1 would lead to the proliferation and migration of papillary TC.7 In order to discover the genes that might be correlated with TC, the Gene Expression Omnibus (GEO) database was employed to retrieve the lncRNA trinucleotide repeat containing 6C (TNRC6C)‐AS1 was overexpressed in TC cells. The gene discussed is TNRC6C; the disease is cancer.
