Editorial Induced cell senescence as a therapeutic Biology Diagrams Cellular senescence is a highly stable cell cycle arrest that is elicited in response to different stresses. By imposing a growth arrest, senescence limits the replication of old or damaged cells. A variety of stressors induce senescence-associated growth arrest. Cell cycle exit is regulated by induction of the p16 INK4a /Rb and p53/p21
Loss of SIRT1 activity is associated with multiple aspects of senescence, including SASP activation 91 and cell cycle arrest 92, as well as several senescence-associated degenerative pathologies These changes have been linked to both the cell-autonomous and paracrine aspects (that is, the effect on surrounding cells) of senescence-associated proliferation arrest. Senescence-associated

Abstract. Background: Cellular senescence is a state of irreversible cell cycle arrest that serves as a critical regulator of tissue homeostasis, aging, and disease.While transient senescence contributes to development, wound healing, and tumor suppression, chronic senescence drives inflammation, tissue dysfunction, and age-related pathologies, including cataracts.
(D-G) Transcriptional expression of cell cycle arrest markers (p16 INK4a, p21 WAF1) and SASP factors (IL-6, IL-1b) within the hippocampus of vehicle-treated cognitively stratified and senolytic-treated aged male mice. (H, I) Quantification and representative images of senescence-associated beta-galactosidase staining within the hippocampus. Cellular senescence is a stable cell cycle arrest that can be triggered in normal cells in response to various intrinsic and extrinsic stimuli, as well as developmental signals.
