MetabolomicsSIRT3-dependent glutaminolysis enhances germinal center epigenetic programming through α-ketoglutarate

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...

MetabolomicsSIRT5 alleviate cardiomyocyte senescence in radiation-induced heart disease via desuccinylation of HADHB

SIRT5 deficiency caused widespread protein hypersuccinylation in cardiac tissue. Succinylation proteomic analysis revealed HADHB as the key SIRT5 target, with lysine 292 (K292) being the dominant succinylation site. Functional studies demonstrated that K292 succinylation impairs HADHB-mediated fa...

MetabolomicsDendrobium officinale Polysaccharide Ameliorates High-Fat Diet-Induced Hepatic Lipid Metabolic Disorder via the SIRT6/PGC-1α Signaling Axis
Aims: This study aims to explore the potential therapeutic effect of Dendrobium officinale polysaccharide (DOP) on non-alcoholic fatty liver disease (NAFLD) induced by high-fat diet (HFD), and to elucidate the underlying mechanism involving the SIRT6/PGC-1α signaling axis and the regulation of the g...

ProteomicsSCFCyclin F targets the metabolic protein Sirtuin 5 for ubiquitination
Cell cycle transitions are regulated by a number of coordinating signaling events. The ubiquitin-proteasome system is an important part of this cell cycle signaling. Cyclin F, a substrate adapter for the SCF (SKP1/CUL1/F-box) E3 ubiquitin ligase, is an important regulator of cell cycle progression. ...
