Senescence-Associated Secretory Phenotype (SASP) in Diabetes

Journal of Pharma Insights and Research
Cellular senescence represents a critical biological process characterized by permanent cell cycle arrest and distinct metabolic alterations. The senescence-associated secretory phenotype (SASP) has emerged as a fundamental mediator linking cellular aging to various pathological conditions, including diabetes mellitus.

Proteostasis of organelles in aging and disease

The FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

α-Lipoic acid alleviate myocardial infarction by suppressing age-independent macrophage senescence

Scientific Reports
Myocardial infarction (MI) has high morbidity and mortality, and the macrophage senescence-associated secretory phenotype (SASP) plays a central role in M1 healing. α-Lipoic acid (ALA) alleviates MI by regulating the function of macrophages, although the

SASP Modulation for Cellular Rejuvenation and Tissue Homeostasis: Therapeutic Strategies and Molecular Insights

Cells
Cellular senescence regulates aging, tissue maintenance, and disease progression through the Senescence-Associated Secretory Phenotype (SASP), a secretory profile of cytokines, chemokines, growth factors, and matrix-remodeling enzymes.

Model and Reinforcement Learning for Markov Games with Risk Preferences

, 2019
We motivate and propose a new model for non-cooperative Markov game which considers the interactions of risk-aware players. This model characterizes the time-consistent dynamic "risk" from both stochastic state transitions (inherent to the game) and ...

Mitochondrial metabolism and epigenetic crosstalk drive the SASP

Abstract Senescent cells drive tissue dysfunction through the senescence-associated secretory phenotype (SASP). We uncovered a central role for mitochondria in the epigenetic regulation of the SASP, where mitochondrial-derived metabolites, specifically citrate and acetyl-CoA, fuel histone acetylation at SASP gene loci, promoting their ...

Systemic, Lifestyle and Environmental Modifying Factors in the Pathogenesis of Periodontitis

Journal of Periodontal Research, EarlyView.
A variety of impacting factors in the pathogenesis of periodontitis exist, including systemic, lifestyle, and environmental factors. This review highlights the manifold mechanistic aspects of the link between the pathogenesis of periodontitis, addressing these numerous factors to supplement the long‐standing knowledge of the progression of the disease.

Profiling with senescence-associated secretory phenotype score identifies GDC-0879 as a small molecule sensitizing glioblastoma to anti-PD1

Cell Death and Disease
Senescence-associated secretory phenotype (SASP) in cancer refers to the bioactive secretome produced by senescence cells in the tumor microenvironment, which could be triggered by therapeutics or local stress conditions.

Inflammation Affects the Osteogenic Differentiation of Aged Periodontal Ligament Cells via NF‐κB/FOXO3a/c‐JUN Signalling

Journal of Periodontal Research, EarlyView.
NF‐κB/FOXO3a/c‐JUN pathway plays a crucial role in osteogenic. Differentiation of aged PDLCs in an inflammatory microenvironment, although the mechanisms of this pathway differ in cellular ageing and pathological inflammation. ABSTRACT Aim This study aims to investigate the effect of inflammation on the senescence phenotype and osteogenic capacity of ...

Modulation of fracture healing by senescence-associated secretory phenotype (SASP): a narrative review of the current literature

European Journal of Medical Research
The senescence-associated secretory phenotype (SASP) is a generic term for the secretion of cytokines, such as pro-inflammatory factors and proteases. It is a crucial feature of senescent cells.
