MetabolomicsL-serine enables reducing the virulence of Acinetobacter baumannii and modulating the SIRT1 pathway to eliminate the pathogen

The emergence of high-virulent Acinetobacter baumannii strains increases the mortality of patients and seriously affects their prognosis, which motivates us to explore novel ways to control such infections. In this study, gas chromatography-mass spectrometry was adopted to explore the me...

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...

ProteomicsConvergence of SIRT1 and ATR signaling to modulate replication origin dormancy
SIRT1 chromatin interactome analysis was performed to identify SIRT1 molecular targets involved in replication initiation from cells containing either WT or H363Y SIRT1. Co-IP-MS of pT530 SIRT1 from chromatin extracts was performed. Files are: 1422 WT SIRT1 untreated U2OS; 1423 WT SIRT1 H2O2 treated...

TranscriptomicsRole of SIRT1 in diet-induced metabolic diseases
The purpose of this study is to investigate the role of SIRT1 in high-fat diet-induced liver steatosis and insulin resistance. SIRT1 is a nuclear enzyme that could remove an acetyl-group from target proteins by using NAD as co-substrate. Homologs of this protein in yeast and the roundworm C. elegans...

TranscriptomicsSIRT1 and H1AcK26 promoter-association in mouse ES cells changes upon oxidative stress
Association of the (histone) deacetylase SIRT1 with promoters was assessed to determine putative SIRT1-regulated genes. Based on the observation that the SIRT1 yeast ortholog Sir2 redistributes across the yeast genome in repsonse to genotoxic stress and double strand breaks (DSBs), we investigated t...

TranscriptomicsNegative reciprocal regulation between Sirt1 and Per2 modulates the circadian clock and aging (microarray expression)
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...

ProteomicsPhosphorylation level of SIRT1 in proliferating and senescent IMR90 cells
Mammalian SIRT1 is a central regulator of metabolism and aging. This project is to analyze global phosphorylation levels of mammalian SIRT1 in proliferating and senescence states using human lung fibroblast IMR90, in order to explore the post-translational regulation of SIRT1 protein upon cellular s...

TranscriptomicsSIRT1 but not its increased expression is essential for lifespan extension in caloric restricted mice.
The SIRT1 deacetylase is one of the best-studied potential mediators of some of the anti-aging effects of calorie restriction (CR); but its role in CR-dependent lifespan extension has not been demonstrated. We previously found that mice lacking both copies of SIRT1 displayed a shorter median lifespa...

TranscriptomicsTranscription profiling of mouse transgenics with cardiac specific overexpression of Sirt1 (Tg-Sirt1) and non-transgenic (NTg) control littermate at 3 months of age
We harvested the heart from transgenic mice with cardiac specific overexpression of Sirt1 (Tg-Sirt1) and non-transgenic (NTg) control littermate at 3 months of age and then microarray analyses were conducted. Experiment Overall Design: Two transgenic mice and two wild type mice were used.
