Paracrine cellular senescence exacerbates biliary injury and impairs regeneration [PDF]

, 2018
Senescence has been suggested as causing biliary cholangiopathies but how this is regulated is unclear. Here, the authors generate a mouse model of biliary senescence by deleting Mdm2 in bile ducts and show that inhibiting TGFβ limits senescence ...

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

ESC 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 ...

Mitochondrial RNA cytosolic leakage drives the SASP

Nature Communications
Senescent cells secrete proinflammatory factors known as the senescence-associated secretory phenotype (SASP), contributing to tissue dysfunction and aging. Mitochondrial dysfunction is a key feature of senescence, influencing SASP via mitochondrial DNA (

GDF15 is associated with hepatocellular senescence and correlates with mortality in patients with alcohol-associated hepatitis

JHEP Reports
Background & Aims: Cellular senescence is characterized by the loss of proliferative capacity, cell cycle arrest, and the acquisition of a proinflammatory senescence-associated secretory phenotype (SASP).

Immune Checkpoint Inhibitors Induce Intestinal Epithelial Injury and a Senescence‐Like Phenotype

iNew Medicine, EarlyView.
ICI treatment promotes the infiltration of activated immune cells into the intestinal mucosa. This inflammatory microenvironment is associated with significant epithelial injury, characterized by the disruption of the epithelial barrier, the depletion of specialized secretory cell lineages, and the induction of a premature senescence phenotype ...

Mitochondria, telomeres and cell senescence: Implications for lung ageing and disease

, 2017
Cellular senescence, the irreversible loss of replicative capacity in somatic cells, plays a causal role in the development of age-related pathology and in a number of age-related chronic inflammatory diseases.

Lysosome-mediated processing of chromatin in senescence [PDF]

, 2013
Cellular senescence is a stable proliferation arrest, a potent tumor suppressor mechanism, and a likely contributor to tissue aging. Cellular senescence involves extensive cellular remodeling, including of chromatin structure. Autophagy and lysosomes are

Vascular Calcification: Mechanisms, Models, and Therapies

iNew Medicine, EarlyView.
ABSTRACT Vascular calcification represents an active multifactorial process that mirrors several key features of skeletal bone mineralization. Clinically, it is characterized by diminished arterial compliance and increased arterial wall stiffness, both of which serve as independent predictors of significant adverse cardiovascular events.
