TTN and neoplasm: The results showed that TTN-AS1 was upregulated in OSCC tissues by 3-fold compared with adjacent normal tissues (Figure 1a), and TTN-AS1 expression was associated with tumor differentiation (P = 0.0010), T-stage (P = 0.0369), and lymph node metastasis (P = 0.0027) (Supplementary Table 1).
