A Bi‐Adjuvant Senolytic Nanovaccine Modulating Dendritic Cell Senescence Ameliorates Aging‐Related Metabolic Dysfunction

open access: yesAdvanced Science, EarlyView.
An active biomaterial‐based bi‐adjuvant nanovaccine restores the immunocompetence of aged dendritic cells to overcome senescent cell tolerance. Accompanied by the downregulation of mitotic kinases Aurka/b and attenuation of senescence‐associated PI3K/AKT phosphorylation, the nanovaccine enhances antigen‐presenting capacity and promotes potent cytotoxic

Cycloastragenol attenuates osteoarthritis by restoring chondrocyte senescence via the NRF2/NF-κB signaling axis

open access: yesScientific Reports
Osteoarthritis (OA) involves oxidative stress-induced chondrocyte senescence and extracellular matrix (ECM) dysregulation, yet disease-modifying therapies remain elusive.

Microenvironment‐Responsive Biomimetic Hydrogels Delivering Cistanche Deserticola‐Derived Nanovesicles for Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
An injectable, microenvironment‐responsive hydrogel (HAPOCS@CDNVs) is developed for sustained delivery of Cistanche deserticola‐derived nanovesicles (CDNVs). By scavenging ROS, restoring mitochondrial function, and attenuating SASP, this platform effectively suppresses nucleus pulposus cell senescence and facilitates extracellular matrix reconstruction,

Large‐Scale Machine Learning to Screen for Small‐Molecule Senolytics

open access: yesAdvanced Intelligent Discovery, EarlyView.
A consistent workflow underpins all experiments in this study. A dedicated model‐selection dataset first identifies optimal hyperparameters for each algorithm. Models are then trained and rigorously evaluated on independent sets of molecules using the senolytic ratio SR. Comprehensive hyperparameter exploration across SMILES representations, task types,

Deciphering the mechanism for induction of senescence-associated secretory phenotype (SASP) and its role in ageing and cancer development

open access: yesThe Journal of Biochemistry, 2019
Abstract Cellular senescence is an irreversible form of cell cycle arrest that can be induced by persistent DNA damage, and is well known to function as an important tumour suppression mechanism. Cellular senescence is detected in aged organisms; thus, it is also recognized as a hallmark of organismal ageing.

Biomimetic Nanomedicine for Aging‐Impaired Bone Regeneration: From Microenvironmental Dysfunction to Precision Therapeutics

open access: yesAdvanced NanoBiomed Research, EarlyView.
Aging disrupts the cellular, immune, vascular, and neural processes required for bone regeneration. This review connects these pathological barriers with biomimetic nanomedicine design, highlighting strategies for cellular rejuvenation, immune modulation, vascular regeneration, and neuro–bone coupling.

Apoptosis signal-regulating kinase 1 promotes inflammation in senescence and aging

open access: yesCommunications Biology
Cellular senescence is a stress-induced, permanent cell cycle arrest involved in tumor suppression and aging. Senescent cells secrete bioactive molecules such as pro-inflammatory cytokines and chemokines.

MDL‐800–Induced Sirtuin 6 Activation Decreases Age‐Associated Osteoarthritis in Mice

open access: yesArthritis &Rheumatology, EarlyView.
Objective Sirtuin 6 (SIRT6) is a nuclear‐localized histone deacetylase that regulates multiple pathways associated with aging. This study aimed to determine whether systemic administration of MDL‐800, a small molecule activator of SIRT6, decreases the severity of age‐associated osteoarthritis (OA) in mice.

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

CDK4/6 inhibition induces a senescence-associated secretory phenotype via delayed NF-κB activation

open access: yesLife Science Alliance
Extended therapeutic inhibition of CDK4/6 pushes cancer cells into a senescent-like state and can trigger NF-κB activation to induce an inflammatory signature in both liposarcoma and ER+ breast cancer cells.
