Perturbation of Ribosome Biogenesis Drives Cells into Senescence through 5S RNP-Mediated p53 Activation

open access: yesCell Reports, 2015
The 5S ribonucleoprotein particle (RNP) complex, consisting of RPL11, RPL5, and 5S rRNA, is implicated in p53 regulation under ribotoxic stress. Here, we show that the 5S RNP contributes to p53 activation and promotes cellular senescence in response to ...

Bovine vitreous gel can reactivate replicative senescence of human dermal fibroblast

open access: yesIndonesian Journal of Biotechnology, 2018
The most influential factor in the poor healing of chronic ulcers is replicative senescence of fibroblasts that are unresponsive to TGF-β1 stimulation.

Global m6A RNA and whole 5mC DNA methylation specifically contribute to cell replicative and premature senescence induced by extrinsic oxidative stress

open access: yesmSystems
Hydrogen peroxide (H2O2) is a typical representative substance of environmental oxidative stress. Exogenous substances can alter epigenetic modifications from the DNA to the RNA level through oxidative stress.

Reprogramming of replicative senescence in hepatocellular carcinoma-derived cells [PDF]

open access: yes, 2006
Tumor cells have the capacity to proliferate indefinitely that is qualified as replicative immortality. This ability contrasts with the intrinsic control of the number of cell divisions in human somatic tissues by a mechanism called replicative ...

Comparative analysis of gene expression data reveals novel targets of senescence-associated microRNAs. [PDF]

open access: yesPLoS ONE, 2014
In the last decades, cellular senescence is viewed as a complex mechanism involved in different processes, ranging from tumor suppression to induction of age-related degenerative alterations.

Influence of Donor Age and Species Longevity on Replicative Cellular Senescence

open access: yes, 2016
The replicative life span of cell strains obtained from multiple explants from the same individual is highly variable, additional variability is added when strains are obtained from different individuals.

DNA damage-dependent mechanisms of ionizing radiation-induced cellular senescence [PDF]

open access: yesPeerJ
Cellular senescence can be broadly categorized into replicative senescence and stress-induced premature senescence. Replicative senescence mainly results from the progressive shortening of telomeres during successive cell divisions, eventually leading to

Deregulation of the imprinted DLK1-DIO3 locus ncRNAs is associated with replicative senescence of human adipose-derived stem cells. [PDF]

open access: yesPLoS ONE, 2018
BACKGROUND:Human adult adipose-derived stem cells (hADSCs) have become the most promising cell source for regenerative medicine. However the prolonged ex vivo expansion periods required to obtain the necessary therapeutic dose promotes progressive ...

Mitochondrial dysfunction accounts for the stochastic heterogeneity in telomere-dependent senescence.

open access: yesPLoS Biology, 2007
Aging is an inherently stochastic process, and its hallmark is heterogeneity between organisms, cell types, and clonal populations, even in identical environments.

Molecular Mechanisms of Alveolar Epithelial Stem Cell Senescence and Senescence-Associated Differentiation Disorders in Pulmonary Fibrosis

open access: yesCells, 2022
Pulmonary senescence is accelerated by unresolved DNA damage response, underpinning susceptibility to pulmonary fibrosis. Recently it was reported that the SARS-Cov-2 viral infection induces acute pulmonary epithelial senescence followed by fibrosis ...
