Figure 1. DLG1-AS1 expression is upregulated in PTC tissues and cell lines. (A) Quantitative real-time reverse transcription-polymerase chain reaction (qRT-PCR) assays showing upregulated expression of DLG1-AS1 in PTC tissues as compared with that in adjacent normal tissues. (B) The qRT-PCR assays reveal upregulated expression of DLG1-AS1 in four PTC cell lines as compared with that in a normal thyroid epithelial cell line (Nthy-ori 3-1). All experiments were performed in triplicate, and data are expressed as mean ± standard deviation (SD) (*P < 0.05, **P < 0.01).
