Targeting PLD3 Reverses the Immunosuppressive Niche by Reprogramming Tumor‐Associated Macrophages and Potentiates Antitumor Immunity

Advanced Science, EarlyView.
PLD3 activates the lysosomal‐AKT‐NF‐κB axis to drive cellular senescence in macrophages, establishing an immunosuppressive TME by limiting the infiltration of cytotoxic T, NK, and NKT cells, which confers resistance to anti‐PD‐1 therapy. Abrine inhibits PLD3 expression, restoring antitumor immunity and synergizing with anti‐PD‐1 treatment.

Senescent Cell Derived Artificial Vesicle‐Based Senolytic Sonovaccine Platform with Augmented Lymph Node Delivery and Antigen Cross‐Presentation Efficacy

Advanced Science, EarlyView.
A senolytic sonovaccine platform (SenoVac) is developed, in which senescent cell‐derived vesicles serve as broad senescent cell antigen reservior. The “2‐step” click chemistry strategy for effective lymph node delivery, and ultrasound‐triggered endosomal escape to boost cross‐presentation, ensures efficient senescent cell clearance and disease ...

Acute phase serum amyloid A induces proinflammatory cytokines and mineralization via toll-like receptor 4 in mesenchymal stem cells

Stem Cell Research, 2015
The role of serum amyloid A (SAA) proteins, which are ligands for toll-like receptors, was analyzed in human bone marrow-derived mesenchymal stem cells (hMSCs) and their osteogenic offspring with a focus on senescence, differentiation and mineralization.

Pericentromeric repetitive ncRNA regulates chromatin interaction and inflammatory gene expression

Nucleus, 2022
Cellular senescence provokes a dramatic alteration of chromatin organization and gene expression profile of proinflammatory factors, thereby contributing to various age-related pathologies via the senescence-associated secretory phenotype (SASP ...

SIRT6‐Mediated Deacetylation of ATF3 Promotes Silica‐Induced Lung Fibrosis by Enhancing its Nuclear Import via Binding to Importin α

Advanced Science, EarlyView.
SIRT6‐mediated ATF3 acetylation drives MGARP transcription and mitochondrial dysfunction in macrophages, promoting macrophage senescence and pulmonary fibrosis. Mechanistically, HSP70/Importin α competitively binds to ATF3, modulating its nuclear translocation.

Renal IGFBP6 Interacts With THBS1 to Drive Renal Cellular Senescence and Fibrosis

Advanced Science, EarlyView.
ABSTRACT Epithelial dedifferentiation and myofibroblast activation are critical drivers of chronic kidney disease (CKD) progression. Elevated levels of IGFBP6 have been linked to decreased renal function in CKD patients, but its precise role and underlying mechanisms remain unclear.

Senescence and fibrosis in salivary gland aging and disease

Journal of Oral Biology and Craniofacial Research
Salivary gland hypofunction is highly prevalent in aged and diseased individuals leading to significant discomfort and morbidity. One factor that contributes to salivary gland hypofunction is cellular aging, or senescence.

RNA-binding Protein Immunoprecipitation (RIP) to Examine AUF1 Binding to Senescence-Associated Secretory Phenotype (SASP) Factor mRNA [PDF]

BIO-PROTOCOL, 2015
Immunoprecipitation and subsequent isolation of nucleic acids allows for the investigation of protein:nucleic acid interactions. RNA-binding protein immunoprecipitation (RIP) is used for the analysis of protein interactions with mRNA. Combining RIP with quantitative real-time PCR (qRT-PCR) further enhances the RIP technique by allowing for the ...
