TUG1 and neoplasm: For instance, lncRNA TUG1 contributes to the progression of PTC by regulating miR‐145.33 Another lncRNA called ABHD11‐AS1 was dramatically upregulated in PTC cells and promoted tumorigenesis via modulating BHD11‐AS1/miR‐199a‐5p/SLC1A5 axis.33 In addition, lncRNA myocardial infarction‐associated transcript (MIAT) was also highly expressed in PTC cells and enhanced tumor progression.34, 35 From our perspective, most of the reported lncRNAs were abnormally upregulated in PTC samples and cells and have negative impact on outcome of PTC patients.
