High calorie diet background alters the expression of sirtuins in the testes of mice under caloric restriction

Translational Medicine of Aging, 2021
Caloric restriction (CR) is considered one of the most efficient interventions that extend lifespan and healthspan by delaying the onset of many age-related diseases in a variety of organisms.

Sirt5 Inhibits BmNPV Replication by Promoting a Relish-Mediated Antiviral Pathway in Bombyx mori

Frontiers in Immunology, 2022
Silent information regulators (Sirtuins) belong to the family of nicotinamide adenine dinucleotide (NAD+)-dependent histone deacetylases (HDACs) that have diverse functions in cells.

Aging Is a Key Driver for Adult Acute Myeloid Leukemia

Aging and Cancer, EarlyView.
Acute myeloid leukemia (AML) is a classical age‐related hematologic malignancy, and a key driver of AML is aging, which profoundly regulates intrinsic factors such as genomic instability, epigenetic reprogramming, and metabolic dysregulation, and alters bone marrow microenvironment.

The Current State of Research on Sirtuin-Mediated Autophagy in Cardiovascular Diseases

Journal of Cardiovascular Development and Disease, 2023
Sirtuins belong to the class III histone deacetylases and possess nicotinamide adenine dinucleotide-dependent deacetylase activity. They are involved in the regulation of multiple signaling pathways implicated in cardiovascular diseases.

Phosphorylation‐Facilitated CKB Lactylation At K11 By GCN5 Enhances Creatine Kinase Activity and Mitigates Neuronal Damage After Cerebral Ischemia‐Reperfusion

Advanced Science, EarlyView.
This study uncovers hierarchical coordination between K11 lactylation and S199 phosphorylation of CKB in cerebral ischemia‐reperfusion injury. Such dual modifications potentiate CKB enzymatic function, remodel energy metabolism, alleviate oxidative stress and neuronal damage, and represent a viable therapeutic target for stroke treatment.

β‐Elemene Rescues Radiation‐Induced Enteritis by Orchestrating a Host‐Microbiome Circuit That Fuels Epigenetic DNA Repair

Advanced Science, EarlyView.
This study elucidates that β‐elemene promotes cellular uptake of L. gasseri‐derived lactate by enhancing the membrane translocation of MCT1 in a CD147‐dependent manner. Intracellular lactate, through the lactylation of RBBP4 at the K26 site, recruits EP300 to the promoter regions of downstream genes (POLD1/POLD3), catalyzing H3K27ac modification.

Neuroprotective potential for mitigating ischemia-reperfusion-induced damage

Neural Regeneration Research
Reperfusion following cerebral ischemia causes both structural and functional damage to brain tissue and could aggravate a patient’s condition; this phenomenon is known as cerebral ischemia-reperfusion injury.

Unveiling Lactylation: A Novel Frontier in Cancer Stemness and Therapy

Advanced Science, EarlyView.
Tumor metabolism and epigenetic regulation are intrinsically linked. This review highlights lactylation as a pivotal bridge connecting these processes, acting as an active epigenetic effector in cancer stemness. We delineate how lactylation orchestrates the cancer stem cell landscape and evaluate its regulatory networks.

Sirtuins and their interactions with transcription factors and poly(ADP-ribose) polymerases

Folia Neuropathologica, 2016
Sirtuins (SIRT1 to -7) are unique histone deacetylases (HDACs) whose activity depends on NAD+, thus making them capable of sensing the cellular metabolic status.

Sirtuins and Their Relevance to the Kidney [PDF]

Journal of the American Society of Nephrology, 2010
Sirtuins (silent information regulator 2 [Sir2] proteins) belong to an ancient family of evolutionary conserved nicotinamide adenine dinucleotide (NAD)(+)-dependent enzymes with deacetylase and/or mono-ADP-ribosyltransferase activity. They regulate DNA repair and recombination, chromosomal stability, and gene transcription, and most importantly mediate
