Mechanisms and Regulation of Cellular Senescence

open access: yesInternational Journal of Molecular Sciences, 2021
Cellular senescence entails a state of an essentially irreversible proliferative arrest in which cells remain metabolically active and secrete a range of pro-inflammatory and proteolytic factors as part of the senescence-associated secretory phenotype ...

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

p16INK4a in cellular senescence

open access: yesAging, 2013
A crucial mechanism in the establishment of cellular senescence is the activation of the INK4/ARF locus, which is epigenetically regulated and under tight control of the Polycomb group (PcG) Trithorax group (TrxG) proteins [1]. In proliferating cells, the locus is silenced by Polycomb repressive complexes (PRCs), and the chromatin is enriched in ...

Cellular senescence mediates fibrotic pulmonary disease

open access: yesNature Communications, 2017
Idiopathic pulmonary fibrosis (IPF) is a fatal disease characterized by interstitial remodelling, leading to compromised lung function. Cellular senescence markers are detectable within IPF lung tissue and senescent cell deletion rejuvenates pulmonary ...

Making tau amyloid models in vitro: a crucial and underestimated challenge

open access: yesFEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Cellular senescence in bone

open access: yesBone, 2019
Cellular senescence refers to a process induced by various types of stress that causes irreversible cell cycle arrest and distinct cellular alterations, including profound changes in gene expression, metabolism, and chromatin organization as well as activation/reinforcement of anti-apoptotic pathways and development of a pro-inflammatory secretome or ...

Cellular Senescence in Cancer and Aging [PDF]

open access: yesCell, 2007
Cellular senescence, a state of irreversible growth arrest, can be triggered by multiple mechanisms including telomere shortening, the epigenetic derepression of the INK4a/ARF locus, and DNA damage. Together these mechanisms limit excessive or aberrant cellular proliferation, and so the state of senescence protects against the development of cancer ...

Lipid Players of Cellular Senescence [PDF]

open access: yesMetabolites, 2020
Lipids are emerging as key players of senescence. Here, we review the exciting new findings on the diverse roles of lipids in cellular senescence, most of which are enabled by the advancements in omics approaches. Senescence is a cellular process in which the cell undergoes growth arrest while retaining metabolic activity.

Metabolic regulation of endothelial senescence

open access: yesFrontiers in Cardiovascular Medicine, 2023
Endothelial cell (EC) senescence is increasingly recognized as a significant contributor to the development of vascular dysfunction and age-related disorders and diseases, including cancer and cardiovascular diseases (CVD).

Oncogenic senescence: a multi-functional perspective. [PDF]

open access: yes, 2017
Cellular senescence is defined as an irreversible growth arrest with the acquisition of a distinctive secretome. The growth arrest is a potent anticancer mechanism whereas the secretome facilitates wound healing, tissue repair, and development.
