Active Regulator of SIRT1 Cooperates with SIRT1 and Facilitates Suppression of p53 Activity [PDF]

Molecular Cell, 2007
Human SIRT1 is an NAD+-dependent deacetylase protein that plays a role in cell death/survival, senescence, and endocrine signaling. While its substrates, including p53, have been well characterized, no direct regulators are known. We describe here a nuclear protein, active regulator of SIRT1 (AROS), which directly regulates SIRT1 function.

Mn/Zn Bimetallic MOF‐Integrated Hydrogel Alleviates Excessive Mitochondrial Fission in BMSCs to Promote Osteoporotic Jawbone Repair

Advanced Science, EarlyView.
Excessive reactive oxygen species (ROS) and chronic inflammation impair bone marrow‐derived mesenchymal stem cells (BMSCs), contributing to poor healing in osteoporotic jawbone defect. The gelatin methacryloyl hydrogel loaded with manganese‐doped zeolitic imidazolate framework (Mn‐ZIF‐8@GelMA) promotes regeneration through redox regulation and ...

HADHA K406 Lactylation Regulates Metabolic Reprogramming and Suppresses Immune Responses in Gastric Cancer

Advanced Science, EarlyView.
HADHA K406 lactylation fuels fatty acid β‐oxidation and HMGCR‐dependent cholesterol biosynthesis, fostering immunosuppressive MDSCs and exhausted CD8+ T cells in gastric cancer. Loss of this modification blocks cholesterol production, remodels the tumor microenvironment, and tumor growth is suppressed via combined inhibition of HMGCR and LDHA ...

Thioredoxin‐2 Alleviates Osteoporosis by Restraining FOXO3a Nuclear Translocation

Advanced Science, EarlyView.
Endothelial TRX2 preserves bone homeostasis by retaining FOXO3a at mitochondria and limiting TRAIL production. Loss of TRX2 or oxidative stress releases FOXO3a for nuclear translocation, increasing endothelial TRAIL secretion and driving osteoclast formation and bone loss.

Glioma-induced SIRT1-dependent activation of hMOF histone H4 lysine 16 acetyltransferase in microglia promotes a tumor supporting phenotype

OncoImmunology, 2018
High-grade gliomas are malignant aggressive primary brain tumors with limited therapeutic options, and dismal prognosis for patients. Microglia, the resident immune cells of the brain, are recruited and reprogrammed into tumor-supporting cells by glioma ...

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.

ZMIZ2–DUX4–LGR5 Signaling Axis Maintains Stemness Properties and Facilitates Docetaxel Resistance in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
This study identifies ZMIZ2 as a therapeutic target for docetaxel‐resistant triple‐negative breast cancer, sustaining cancer stemness‐associated properties and docetaxel resistance. ZMIZ2 upregulation enhances DUX4‐mediated LGR5 activation through the SWI/SNF components BRG1 and BAF57.

Chrysanthemum Morifolium–Derived Nanovesicles Reduce Lactate‐Associated Histone Lactylation and Modulate Microglia‐Mediated Neuroinflammation in Sepsis‐Associated Encephalopathy

Advanced Science, EarlyView.
When used to treat sepsis‐associated encephalopathy, Chrysanthemum morifolium–derived nanovesicles can inhibit the H3K18la/NF‐κB axis to regulate microglia‐mediated neuroinflammation. ABSTRACT Sepsis‐associated encephalopathy (SAE)—a complication of the central nervous system in patients with sepsis—markedly diminishes cognitive functions and is linked
