Targeting histone/protein deacetylase (HDAC)-6, -9, or Sirtuin-1 (Sirt1) augments the suppressive functions of Foxp3+ T regulatory (Treg) cells, but it is unclear if this involves different mechanisms, such that combined inhibition would be beneficial. We compared the suppressive functions of Tregs ...

Early diabetic kidney disease (DKD) is marked by dramatic metabolic reprogramming due to nutrient excess, mitochondrial dysfunction, and increased renal energy requirements from hyperfiltration. We hypothesized that changes in metabolism in DKD may be regulated by Sirtuin 5 (SIRT5), a deacylase that...

Germinal center (GC) B cells depend on sustained epigenetic modulation to maintain transcriptional identity and support affinity maturation; however, whether mitochondrial metabolism directly enhances this chromatin state remains unclear. Here, we show that enhanced SIRT3 activity promotes glutam...

Nigral dopaminergic sirtuin 3 inhibits aging-related locomotor decline
Sirtuins (SIRTs) form a critical family of nicotinamide adenine dinucleotide (NAD)-dependent enzymes that govern genome regulation, metabolism, and aging. Despite conserved deacetylase domains, SIRTs4-7 have little to no deacetylase activity, and a robust catalytic activity for mitochondrial SIRT4 h...

We applied SD-SILAC to determine absolute acetylation stoichiometry in exponentially-growing and stationary-phase wild type and sirtuin deacetylase CobB-deficient E. coli. We further assayed stoichiometry in phophotransacetylase (pta) and acetate kinase (ackA) mutant strains in the presence and abse...

Sirtuin 1 (SIRT1) is involved in both aging and circadian-clock regulation, yet the link between the two processes in relation to SIRT1 function is not clear. Using Sirt1-deficient mice, we found that Sirt1 and Period 2 (Per2) constitute a reciprocal negative regulation loop that plays important rol...

Lithocholic acid (LCA), accumulated in mammals during calorie restriction (CR), can activate AMP-activated protein kinase (AMPK) and slow down ageing1. However, how LCA is signalled to activate AMPK and elicit the biological effects is unclear. Here, we show that LCA can enhance the activity of sirt...
