Sirtuins and Their Relevance to the Kidney [PDF]

open access: yesJournal 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

Inhibition of SIRT7 Overcomes Radioresistance in Pancreatic Neuroendocrine Tumors by Reactivating MEN1 Expression

open access: yesAdvanced Science, EarlyView.
Pancreatic neuroendocrine tumors frequently silence MEN1 through epigenetic mechanisms. Here, SIRT7 recruits DNMT1 to the MEN1 promoter, drives hypermethylation, and enhances DNA repair. Inhibiting SIRT7 restores MEN1, reduces MRN complex abundance, impairs double‐strand break repair, and sensitizes PanNET models to radiation, supporting SIRT7 as a ...

CK2α Deficiency Drives Myocardial Fibrosis via Desmin‐Induced Mitochondrial Dysfunction

open access: yesAdvanced Science, EarlyView.
CK2α preserves mitochondrial homeostasis by phosphorylating Desmin to recruit Cryab, ensuring proper filament assembly. CK2α deficiency disrupts this interaction, causing mitochondrial dysfunction, metabolic shifts, bioenergetic failure, and oxidative stress—ultimately establishing a pro‐fibrotic environment that drives cardiac fibrosis.

Role of sirtuins in obesity and osteoporosis: molecular mechanisms and therapeutic targets

open access: yesCell Communication and Signaling
The prevalence of obesity and osteoporosis (OP) represents a significant public health concern on a global scale. A substantial body of evidence indicates that there is a complex relationship between obesity and OP, with a correlation between the ...

Sirtuin activators as an anti-aging intervention for longevity [PDF]

open access: yesExploration of Drug Science
Sirtuins are a family of NAD+-dependent class III histone deacetylases that regulate histones and other proteins. The mammalian sirtuins comprise seven members that have a role in energy metabolism, DNA repair, inflammation, cell survival, apoptosis ...

SIRT1 and SIRT2 Activity Control in Neurodegenerative Diseases

open access: yesFrontiers in Pharmacology, 2021
Sirtuins are NAD+ dependent histone deacetylases (HDAC) that play a pivotal role in neuroprotection and cellular senescence. SIRT1-7 are different homologs from sirtuins.

SIRTain regulators of premature senescence and accelerated aging. [PDF]

open access: yes, 2015
The sirtuin proteins constitute class III histone deacetylases (HDACs). These evolutionarily conserved NAD(+)-dependent enzymes form an important component in a variety of cellular and biological processes with highly divergent as well as convergent ...

T‐Cell Exhaustion in the Tumor Microenvironment: Subcellular Dysfunction, Pan‐Cancer Characteristics, and Therapeutic Interventions

open access: yesAdvanced Science, EarlyView.
This study elucidates the mechanisms of subcellular multidimensional collapse in exhausted T cells. By specifically targeting the nucleus, mitochondria, and endoplasmic reticulum, strategic interventions can effectively remodel the compromised organelle network. This integrated approach drives comprehensive T cell resuscitation, ultimately establishing
