TLDR
It is demonstrated that the SASP can cause paracrine senescence and impact on tumour suppression andSenescence in vivo and TGF-β ligands play a major role by regulating p15INK4b and p21CIP1.Abstract:
Oncogene-induced senescence (OIS) is crucial for tumour suppression. Senescent cells implement a complex pro-inflammatory response termed the senescence-associated secretory phenotype (SASP). The SASP reinforces senescence, activates immune surveillance and paradoxically also has pro-tumorigenic properties. Here, we present evidence that the SASP can also induce paracrine senescence in normal cells both in culture and in human and mouse models of OIS in vivo. Coupling quantitative proteomics with small-molecule screens, we identified multiple SASP components mediating paracrine senescence, including TGF-β family ligands, VEGF, CCL2 and CCL20. Amongst them, TGF-β ligands play a major role by regulating p15(INK4b) and p21(CIP1). Expression of the SASP is controlled by inflammasome-mediated IL-1 signalling. The inflammasome and IL-1 signalling are activated in senescent cells and IL-1α expression can reproduce SASP activation, resulting in senescence. Our results demonstrate that the SASP can cause paracrine senescence and impact on tumour suppression and senescence in vivo.read more

TL;DR: The consideration of a cellular reprogramming-centered view of epigenetic plasticity as a fundamental element of a tissue's capacity to undergo successful repair, aging degeneration or malignant transformation should provide challenging stochastic insights into the current deterministic genetic paradigm for most chronic diseases.

TL;DR: In this article, the authors utilized human pluripotent stem cell-derived cortical brain organoids to study ataxia-telangiectasia (A-T) neuropathology, which is characterized by chronic inflammation, neurodegeneration and premature ageing features that are associated with increased genome instability, nuclear shape alterations, micronuclei accumulation, neuronal defects and premature entry into cellular senescence.

Klotho retards renal fibrosis through targeting mitochondrial dysfunction and cellular senescence in renal tubular cells.
TL;DR: In this article, the role of Klotho in mitochondrial dysfunction in chronic kidney disease (CKD) has not yet been determined, however, it has been shown that the anti-aging protein is predominantly expressed in renal tubular epithelial cells.

TL;DR: Treatment with the nonsteroidal anti‐inflammatory drug (NASID) ibuprofen reduced neuroinflammation and senescent cell burden resulting in significant improvements in cognitive function and gamma frequency oscillations, which support the hypothesis that chronic inflammation is a causal factor in the cognitive decline observed during aging.

TL;DR: A consideration of the cause of the eventual degeneration of these strains leads to the hypothesis that non-cumulative external factors are excluded and that the phenomenon is attributable to intrinsic factors which are expressed as senescence at the cellular level.
