The anti-HIV drug elvitegravir inhibited metastasis by directly targeting METTL3 and enhancing stress-inducible phosphoprotein 1 homology and U-box containing protein 1 (STUB1)-mediated proteasomal degradation in esophageal squamous cell carcinoma (ESCC) [107]. This evidence concerns the gene METTL3 and esophageal squamous cell carcinoma.
