METTL3 and neoplasm: Subsequently, the expression of METTL3 and YAP1 in tumor tissues was detected by immunohistochemistry, revealing that the expression level of METTL3 in tumor tissues positively correlated with the expression level of YAP1; the expression level of METTL3 also decreased after the YAP1 signaling pathway was inhibited by peptide 17 (Figure 6(d)).
