A systematic evaluation of SIRT6 as transcriptomic biomarker of aging
SIRT6 is a NAD+-dependent sirtuin that plays central roles in chromatin regulation, DNA repair, telomere maintenance, metabolic homeostasis, and inflammatory control. Although SIRT6 have long been implicated in aging because of its association with several hallmarks of aging, the available evidence remains largely context-dependent and mechanistic, limiting the interpretation of SIRT6 as a robust…
SIRT6 is a protein that regulates various cellular processes, including DNA repair, telomere maintenance, and metabolic homeostasis. It has been linked to aging due to its involvement in several aging-related processes. However, the evidence for SIRT6 as a reliable biomarker of aging has been inconsistent and context-specific. To better understand SIRT6's role in aging, researchers created a database called SIRT6.db, which compiles data from numerous studies on SIRT6 across different species.
By analyzing this database, the study identified both unique and shared patterns in how SIRT6 affects gene expression and cellular function in response to aging. The findings suggest that SIRT6 levels remain relatively constant as organisms age normally. However, SIRT6 expression can become disrupted in specific types of cells and at particular stages in Alzheimer's disease.
This highlights how the potential of SIRT6 as a biomarker for aging can vary depending on the context.
