Unbiased analysis of senescence associated secretory phenotype (SASP) to identify common components following different genotoxic stresses

Aging, 2016
Senescent cells secrete senescence-associated secretory phenotype (SASP) proteins to carry out several functions, such as sensitizing surrounding cells to senesce; immunomodulation; impairing or fostering cancer growth; and promoting tissue development.

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.

Senescence-associated secretory phenotype in lung cancer: remodeling the tumor microenvironment for metastasis and immune suppression

Frontiers in Oncology
Cellular senescence exerts dual roles in lung cancer pathogenesis: initially suppressing tumorigenesis via p53/p21/p16-mediated cell cycle arrest, but promoting malignancy through the senescence-associated secretory phenotype (SASP).

Senescence And The Senescence Associated Secretory Phenotype In Salivary Hypofunction [PDF]

Cellular senescence, a triggered permanent cycle arrest, occurs with aging and is a component of many aging-related diseases. Triggers for senescence may include pathways involving DNA damage, telomere dysfunction, release of reactive oxygen species, and

LncRNA FLJ20021 Restrains Fibroblast Senescence and Matrix Remodeling in Pelvic Organ Prolapse by Promoting XRCC6‐Dependent ADI1 Transcription

Advanced Science, EarlyView.
FLJ20021 interacts with XRCC6 to regulate ADI1 transcription and downstream cellular phenotypes in hUSLFs. Reduced FLJ20021 in POP is associated with lower ADI1, increased apoptosis, senescence, and an ECM‐degrading marker profile. Conversely, FLJ20021 overexpression enhances XRCC6‐dependent ADI1 expression, reduces apoptosis and senescence, and shifts

Donor‐Cell Senescence Redirects PINK1‐Marked Mitochondrial Cargo From Mitophagy to Microvesicle Transfer Through SUMO3‐Stabilized HSPA9

Advanced Science, EarlyView.
ABSTRACT Extracellular vesicle therapies have been developed for tissue repair, but how donor‐cell senescence reshapes vesicle‐mediated mitochondrial transfer remains unclear. Here, we show that senescent adipose‐derived stem cells (ADSCs) redirect damaged mitochondria into microvesicles (MVs), converting protective vesicles into pro‐degenerative ...

Human CD8+ EMRA T cells display a senescence-associated secretory phenotype regulated by p38 MAPK [PDF]

, 2018
Cellular senescence is accompanied by a senescence-associated secretory phenotype (SASP). We show here that primary human senescent CD8+ T cells also display a SASP comprising chemokines, cytokines and extracellular matrix remodelling proteases that are ...

Lithium‐Doped Hydroxyapatite Nanowires Rejuvenate Senescent Macrophages Via the Lysosome‐Dependent Ferroptosis Axis to Promote Aged Bone Regeneration

Advanced Science, EarlyView.
Li‐nHAP+GelMA promotes mandibular bone regeneration in aged mice by remodeling the senescent immune microenvironment. Local delivery of Li‐nHAP restores lysosomal homeostasis in senescent macrophages, reduces intracellular labile Fe2+ accumulation, ROS production, and lipid peroxidation, thereby suppressing macrophage ferroptosis and senescence ...

Identification and study of a role for toll-like receptors in oncogene-induced senescence

, 2018
Oncogene-induced senescence (OIS) is a fail-safe mechanism activated to halt the proliferation of cells at risk of malignant transformation. It is a cell cycle arrest program of biological changes to the cell comprising of the activation of tumour ...
