Figure 3. Biological functions of SIRT1.

Figure 3

SIRT1 promotes chromatin silencing through chromatin modification, mainly deacetylation, and regulates glucose and lipid metabolism, circadian rhythms, mitochondrial biogenesis, stress responses, apoptosis, inflammation and autophagy by deacetylating non-histone proteins, including transcription factors and transcriptional co-regulatory proteins.
