Hallmarks of senescence and aging

Senescence and aging can be observed from different aspects so that this topic can be observed in the context of research of mainly human fibroblasts, leukocytes, cell cultures and animal leukocytes and intestinal crypt enterocytes, dermal fibroblasts5, 7, 10, 11

Senescence in the aging process — The University of …

title = “Senescence in the aging process”, abstract = “The accumulation of {\textquoteleft}senescent{\textquoteright} cells has long been proposed to act as an ageing mechanism.
A new collaborative NIH initiative on cellular senescence
Three new funding opportunities — budgeted for $191 million over 5 years through an NIH Common Fund initiative co-coordinated by NIA and the National Cancer Institute — are designed to help accelerate growing field of cellular senescence.
Senescence & the Biology of Aging
Senescence, or biological aging, is the breakdown of the physical body as people grow older. Some elements of biological aging are common in most or all of the population, but people also age

A multidimensional systems biology analysis of cellular …

 · Cellular senescence is one of the hallmarks of aging [] and the accumulation of senescent cells in human tissues with age has been implicated as a driver of aging-related diseases. Indeed, pharmacological approaches targeting senescent cells, like senolytics, are a major and timely area of research that could result in human clinical applications [ 5 , 88 ].
Cellular Senescence in Aging Primates
The aging of organisms is characterized by a gradual functional decline of all organ systems. Mammalian somatic cells in culture display a limited proliferative life span, at the end of which they undergo an irreversible cell cycle arrest known as replicative senescence. Whether cellular senescence contributes to organismal aging has been controversial. We investigated telomere dysfunction, a

ROS, Cell Senescence, and Novel Molecular Mechanisms …

Cell Senescence in Aging and Age-Related Diseases (ROS Effect) The “replicative cell senescence” is considered an aging hallmark on the basis of two motives: (1) the senescent cells accumulate in organismal tissues, by rate and proportion, which parallel the

Osteocyte Cellular Senescence
 · Osteocyte senescence is linked to bone loss associated with aging and other conditions. Senescent osteocytes are potential therapeutic targets to alleviate skeletal dysfunction. Additional studies better defining the underlying mechanisms as well as translating these exciting findings from mouse models to humans are needed.

 · A Adams, Peter He works on the role of chromatin in cell senescence. More Details › Adjaye, James He works on development, stem cells and aging. More Details › Aiken, Judd He works primarily on mitochondrial aging. His research is mostly conducted on mice

(PDF) Senescence and aging: Causes, consequences, …

Senescence as a central hallmark of aging. Telomere damage, epigenetic dysregulation, DNA damage, and mitochondrial dysfunction are primary drivers of damage in aging. Several of these drivers of

Reducing Hypothalamic Stem Cell Senescence Protects …

They found that Hnscr depletion is sufficient to cause senescence of these stem cells and aging-like phenotypes in mice. They also identified a natural small compound, theaflavin 3-gallate, which a key component of black tea, that mimics the action of Hnscr , and its use in mice greatly reduced the senescence of htNSCs while preventing aging-related physiological disorders.

Infographic: How Does Cell Senescence Drive Aging …

How aging-related cellular processes drive senescence Untangling which cellular processes drive senescence is a major challenge to researchers, in part because those pathways are interrelated. In addition, there may well be multiple factors that contribute to the accumulation of senescent cells, including the tissue or organ in question, a person’s genetic makeup, and environmental stressors
What is Senescence?
The link between senescence, aging, and age-related pathologies, including cancer, neurodegeneration, and metabolic and cardiovascular diseases have largely fueled the senescence research field. Cellular senescence was first described by Hayflick and Moorhead as a permanent cell cycle arrest occurring when cultured cells reach their replicative limit (replicative senescence).
Aging, life span, and senescence
Research in the field of aging recently has entered a new era. Model systems have begun to provide insight into cellular, molecular, and organismal changes that are related intimately to aging. One important approach has been the identification of genes that determine the life span of an organism. The very existence of genes that when mutated can extend life span suggests that one or a few
Targeting metabolism to influence aging
Aging can be defined by a progressive decline in tissue function and is a risk factor for many pathologies, including fibrosis and cancer. There is emerging evidence suggesting that cellular senescence, which has been studied in cancer, is a key biological process that links multiple pathologies of aging.

P53 and DNA Methylation in the Aging Process

 · The aging of life begins with the senescence of cells. The reason for cell senescence is that the cell cycle is out of control [12]. Among the cell cycle regulation mechanism, the P53 pathway plays a …

The aging endothelium in: Vascular Biology Volume 3 …

Aging is a known risk factor for both of these metabolic diseases, thus, suggesting that cellular senescence may provide a nexus between aging and metabolic disorders. Indeed β–cell senescence has been identified in pancreatic islets isolated from aged …
