Metabolic Signatures for Liver Cancer Diagnosis and Mechanistic Insights: A Large‐Scale, Multicenter Study

Advanced Science, EarlyView.
A large‐scale multicenter serum metabolomics study (13 centers, n = 2,149) identified a 9‐metabolite + AFP diagnostic signature for liver cancer (AUC = 0.93). Among the signature, nicotinamide (NAM) was validated as an oncometabolite: NAM enhances NAD+ synthesis, activating SIRT1 to deacetylate and stabilize HIF1α, thereby driving glycolysis, MAPK ...

Heterogeneous Nuclear Ribonucleoprotein F Stimulates Sirtuin-1 Gene Expression and Attenuates Nephropathy Progression in Diabetic Mice

, 2017
We investigated the mechanism of heterogeneous nuclear ribonucleoprotein F (hnRNP F) renoprotective action in a type 2 diabetes (T2D) mouse model (db/db).

H4K12 Lactylation Impairs Dopaminergic Neuron Energy Metabolism via the HIF‐1α/NDUFS1 Pathway in Parkinson's Disease

Advanced Science, EarlyView.
Lactate and H4K12la are elevated in Parkinson's disease. Mechanistically, p300‐mediated H4K12la enrichment at the HIF‐1α promoter upregulates HIF‐1α, which represses Ndufs1, impairing mitochondrial respiration and energy homeostasis in DA neurons.

Sirtuin 1: A Target for Kidney Diseases

Molecular Medicine, 2015
Sirtuin 1 (SIRT1) is an evolutionarily conserved NAD(+)-dependent histone deacetylase that is necessary for caloric restriction-related lifespan extension. SIRT1, as an intracellular energy sensor, detects the concentration of intracellular NAD(+) and uses this information to adapt cellular energy output to cellular energy requirements.

Mitochondrial Quality Control in Degenerative Musculoskeletal Diseases: Signaling Networks and Therapeutic Landscapes

Advanced Science, EarlyView.
Mitochondrial quality control (MQC) collapse redefines osteoarthritis, intervertebral disc degeneration, and osteoporosis as disorders of organelle dysfunction. Damaged mitochondria leak mtDNA and metabolites, driving cGAS‐STING inflammation, epigenetic reprogramming, and metabolic memory.

Dietary Glutamine Supplementation Alleviated Rumen Epithelium Oxidative Damage and Apoptosis Induced by Feed Restriction via Maintaining Mitochondrial Homeostasis in Female Yaks

Animal Research and One Health, EarlyView.
Dietary glutamine (Gln) supplementation increased the ATP levels and promoted cell proliferation in the rumen epithelium of feed‐restricted yaks. Besides, Gln inhibited ROS accumulation and reduced oxidative damage and apoptosis in the rumen epithelium of feed‐restricted yaks.

Sirtuin 2 Contributes to Pancreatic Injury and Inflammation by Modulating Immediate Early Response 3–Mediated Ferroptosis in Acute Pancreatitis

Cellular and Molecular Gastroenterology and Hepatology
Background & Aims: Acute pancreatitis is a potentially life-threatening inflammatory disorder characterized by trypsin overactivation within acinar cells. Although sirtuin 2 is linked to inflammation, its precise role in acute pancreatitis remains poorly

Indole‐3‐Acetic Acid Protects Bovine Hepatocytes Against Palmitic Acid‐Induced Lipid Accumulation and ER Stress Through SIRT3

Animal Research and One Health, EarlyView.
Cows with ketosis during the perinatal period often experience damage to the liver, a core metabolic organ, thereby exacerbating the disease's inherent vicious cycle. This study indicates that serum 3‐IAA concentrations were reduced in ketotic cows and show a significant negative correlation with hepatic TG content.

Activators of Sirtuin-1 and their Involvement in Cardioprotection

Current Medicinal Chemistry, 2018
SIRT1 is a nicotinamide adenosine dinucleotide (NAD+)-dependent deacetylase, which removes acetyl groups from many target proteins, such as histone proteins, transcription factors and cofactors. SIRT1-catalyzed deacetylation of these factors modulates the activity of downstream proteins, thus influencing many biological processes.

MDL‐800‐induced SIRT6 activation decreases age‐associated osteoarthritis in mice

Arthritis &Rheumatology, Accepted Article.
Objective SIRT6 is a nuclear‐localized histone deacetylase that regulates multiple pathways associated with aging. This study aimed to determine whether systemic administration of a small molecule activator of SIRT6, MDL‐800, decreases the severity of age‐associated osteoarthritis (OA) in mice.
