Cellular senescence is defined by permanent cell cycle arrest. Senescent cells accumulate with age and contribute to the normal aging process as well as age-related disorders. The link between senescence, aging, and age-related pathologies, including cancer, neurodegeneration, and metabolic and cardiova...
Cancer therapeutics are primarily thought to work by inducing apoptosis in tumor cells. However, various tumor suppressors and oncogenes have been shown to regulate senescence in normal cells, and senescence bypass appears to be an important step in the development of cancer. Cellular senescence ...
Recently, it has become evident that anticancer treatment induces senescence in cancer cells. Moreover, certain hallmarks of senescence were detected in non-proliferating post-mitotic cells. There are many signalling pathways involved in cell senescence, but the most prevalent is the DNA damage ...
Apart from a significant increase in our understanding of the mechanisms for uptake, cell clearance is a basic mechanism in tissue homeostasis, cancer, resolution of inflammation, induction of tolerance, and autoimmunity. Phagocytosis of dying cells is a complex process, involving many interacting ...
As we grow older, aches and pains can become a chronic part of life. But experts say it doesn't have to—and solutions are on the way.

And the 3rd stage is ‘senescence’ where the cell stops dividing entirely. They remain alive for a while and then do a particularly disturbing thing. They commit suicide. This programmed cell death is called ‘apoptosis’. This cell life cycle occurs throughout your body and its trillions of...
Cellular senescence is a state of stable cell cycle arrest. Cells remain metabolically active, but no longer divide or respond to growth-promoting stimuli.
