LncRNA TNRC6C‐AS1 has been reported to play a tumorigenic role in the tumour occurrence and invasive ability of papillary thyroid carcinoma (PTC).8 A new study has found that lncRNA TNRC6C‐AS1 affects the development of TC by regulating UNC5B expression as a competitive endogenous RNA of microRNA‐129‐5p (miR‐129‐5p).9 The complementary pairing sites in the promoter regions of lncRNA TNRC6C‐AS1 and serine/threonine‐protein kinase 4 (STK4) genes were analysed by bioinformatics. The gene discussed is TNRC6C; the disease is neoplasm.
