Molecular, Cellular, and Physiological Characterization of Sirtuin 7 (SIRT7) [PDF]

, 2016
Sirtuin 7 (SIRT7), a histone 3 lysine 18 (H3K18) deacetylase, functions at chromatin to suppress endoplasmic reticulum (ER) stress and mitochondrial protein folding stress (PFS(mt)), and prevent the development of fatty liver disease and hematopoietic stem cell aging.

Phase Separation of NFIB Suppresses SLC3A2‐Mediated Ferroptosis in Castration‐Resistant Prostate Cancer

Advanced Science, Volume 13, Issue 26, 8 May 2026.
Castration‐resistant prostate cancer (CRPC) remains sensitive to ferroptosis, but its intrinsic resistance is poorly understood. Here, we identify NFIB as a master suppressor. SIRT7‐mediated NFIB acetylation drives its liquid–liquid phase separation, which promotes SLC3A2 transcription to inhibit ferroptosis.

Characterization of Sirt2 using conditional RNAi in mice [PDF]

, 2011
Within the past eight years, RNA interference (RNAi) has emerged as a powerful experimental tool for gene function analysis in mice. Reversible control of shRNA mediated RNAi has been achieved by using a tetracycline (tet)-inducible promoter.

SIRT7-dependent deacetylation of CDK9 activates RNA polymerase II transcription [PDF]

Nucleic Acids Research, 2017
Abstract SIRT7 is an NAD+-dependent protein deacetylase that regulates cell growth and proliferation. Previous studies have shown that SIRT7 is required for RNA polymerase I (Pol I) transcription and pre-rRNA processing. Here, we took a proteomic approach to identify novel molecular targets and characterize the role of SIRT7 in non ...

SIRT7 inhibits cerebral ischemic injury by inhibiting microglia M1 polarization via desuccinylation of NAMPT

Brain Research Bulletin
Cerebral ischemic injury continues to be a leading cause of mortality and disability worldwide. Although Sirtuin 7 (SIRT7), a desuccinylase, is known to regulate protein expression, its role in cerebral ischemia remains unclear.

MG53 alleviates hypoxia/reoxygenation-induced cardiomyocyte injury by succinylation and ubiquitination modification

Clinical and Experimental Hypertension, 2023
Background Mitsugumin 53 (MG53) is a membrane repair factor that is associated with acute myocardial infarction. This study aimed to investigate the effects of MG53 on cardiomyocyte injury and the posttranslational modification of MG53.

Atrophic Skeletal Muscle‐Derived Extracellular Vesicles Transfer miR‐125a‐5p to Inhibit Bone Formation in Osteoporosis during Aging

Advanced Science, Volume 13, Issue 25, 4 May 2026.
A muscle‐bone endocrine pathway in aging is revealed in which extracellular vesicles released from atrophic skeletal muscle (Aged‐SKM‐EVs) inhibit bone formation. These EVs deliver miR‐125a‐5p to osteoblasts, thereby suppressing the SIRT7‐Sp7 signaling axis and osteogenic differentiation.

Sirtuin 7 Promotes Mesenchymal to Epithelial Transition by β-Catenin Redistribution and Stabilization

Frontiers in Oncology, 2020
SIRT7 belongs to the family of “NAD+ dependent deacetylases” called Sirtuins. In the present work we report a novel role of SIRT7 in regulating cellular polarity.

Chronic exposure to simulated space conditions predominantly affects cytoskeleton remodeling and oxidative stress response in mouse fetal fibroblasts [PDF]

, 2014
Microgravity and cosmic rays as found in space are difficult to recreate on earth. However, ground-based models exist to simulate space flight experiments.

Sirt3 Genetically Engineered Apoptotic Bodies Alleviate Skeletal Aging by Limiting Aggravated NLRP3 Inflammasome Activation of Senescent Macrophages

Advanced Science, Volume 13, Issue 26, 8 May 2026.
The senescence of macrophages leads to a decrease in the expression of Sirtuin3 (Sirt3), which in turn aggravates the NLRP3 inflammasome activation and IL‐1β secretion, thereby promoting the aging‐related osteoporosis. Sirt3‐enriched apoptotic bodies (ABs‐Sirt3) generated through genetic editing approaches can alleviate skeletal aging by targeting ...
