The association between cancer and several other mitochondrial-related proteins, such as silent information regulator 3 (SIRT3), mitochondrial tumor suppressor gene 1 (MTUS1), and 8-hydroxyguanine DNA glycosylase (OGG1), has been reported [11,12,13,14,15,16,17,18,19,20,21,22]. Here, SIRT3 is linked to cancer.
