To further investigate the possible mechanism of MTDH regulating EMT, given that m6A RNA methylation is crucial for promoting EMT in cancer (Chen et al., 2020; Jin et al., 2020; Lin et al., 2019; Ma et al., 2021; Xu et al., 2021), the correlation between m6A RNA methylation and MTDH was performed. The gene discussed is MTDH; the disease is cancer.
