MT1M is also highly involved in cancer, for example, in esophageal squamous cell carcinoma (ESCC) the MT1M expression levels were found to be downregulated, and after its upregulation was induced, MT1M was found to inhibit esophageal cancer cell carcinogenesis through inhibition of epithelial-mesenchymal transition and SOD1/PI3K axis [30]. Here, MT1M is linked to esophageal squamous cell carcinoma.
