MTDH and cancer: Moreover, the protein-protein interaction network including m6A RNA methylation-associated genes, EMT-associated genes, and the most MTDH-associated differently expressed genes showed a comprehensive connection between MTDH, EMT, and m6A RNA methylation in multiple molecular levels (Figure 7B), which indicated that a molecular pathway from MTDH to m6A RNA methylation and EMT might exist in cancers.
