– SIRT6 is involved in maintaining genomic stability through its roles in DNA repair and chromatin remodeling.
– By promoting efficient DNA repair, SIRT6 may help prevent the accumulation of genetic mutations that drive tumorigenesis.
– In several studies, lower SIRT6 expression has been associated with more aggressive tumor behavior and poorer overall survival, supporting its role as a tumor suppressor in those contexts.
– Conversely, in some cancers, higher SIRT6 expression has been linked to enhanced survival signaling or metabolic reprogramming that might support tumor growth, suggesting a possible oncogenic role.
