Among seven identified members (SIRT1-7) of these histone deacetylases, sirtuin 6 (SIRT6) has been shown to be involved in cellular pathways and to play a critical role in regulating ageing and sugar metabolism, both of which are associated with the occurrence and development of tumours and are thus significantly associated with cancer patient prognosis [3, 4]. This evidence concerns the gene SIRT6 and neoplasm.
