Compared with the sh-NC + oe-NC-treated mice, the tumor growth of the oe-CCAT2 + sh-NC-treated mice was increased, (Figures 7A–C), CCAT2 expression was increased (Figure 7D), miR-200b expression was decreased (Figure 7E), mRNA and protein expression of IGF2BP2 and TK1 were increased (Figures 7F, G), and the m6A modification level of TK1 was also increased (Figure 7H). The gene discussed is TK1; the disease is neoplasm.
