Dysfunctional telomeres induce p53-dependent cellular senescence and apoptosis, but it is not known which function is more important for tumour suppression in vivo. We used the p53 ( R172P ) knock-in mouse, which is unable to induce apoptosis but retains intact cell-cycle arrest and cellular senescence pathways, to show that spontaneous tumorigenesis is potently repressed in Terc -/- p53 ( R172...

Atherosclerosis is classed as a disease of aging, such that increasing age is an independent risk factor for the development of atherosclerosis. Atherosclerosis is also associated with premature biological aging, as atherosclerotic plaques show evidence of cellular senescence characterized by reduced cell proliferation, irreversible growth arrest and apoptosis, elevated DNA damage, epigenetic m...

Wound healing is an essential physiological process to restore normal skin structure and function after injury. Cellular senescence, irreversible cell cycle state in response damaging stimuli, has emerged as a paradigm shift disrupt the traditional concept of wound beyond described inflammatory, proliferative, remodeling phases. We hypothesized that senescent cells, particularly fibroblasts, pl...

Introduction Cellular senescence (CS) plays a critical role in cancer development, including clear cell renal carcinoma (ccRCC). Traditional RNA sequencing cannot detect precise molecular composition changes within tumors. This study aimed to analyze cellular senescence’s biochemical characteristics ccRCC using single (ScRNA-seq) and traditional (Bulk RNA-seq). Methods Researchers analyzed the ...

Cellular senescence is an important part of the aging process and forms basis age-related diseases. In our study, we discussed relationship between mammalian target rapamycin (mTOR) signaling pathway polyphenols that affect this cellular senescence. For this, determined keywords 'mTOR' or 'polyphenol' 'cellular aging'. We searched these in scientific databases such as Scopus, Institute for Scie...

Cellular senescence can be described as a complex stress response that leads to irreversible cell cycle arrest. This process was originally described as an event that primary cells go through after many passages of cells during cell culture. More recently, cellular senescence is viewed as a programmed process by which the cell displays a senescence phenotype when exposed to a variety of stresse...

Cellular senescence is reportedly involved in the pathogenesis of chronic obstructive pulmonary disease (COPD). We previously showed that 27-hydroxycholesterol (27-OHC) is elevated in the airways of COPD patients compared with those in healthy subjects. The aim of this study was to investigate whether lung fibroblasts of COPD patients are senescent and to determine the effects of 27-OHC on sene...

Cellular senescence is another mechanism that can be exploited to achieve better chemosensitivity and greater tumor regression. Unlike apoptosis, cellular senescence can be induced at much lower concentrations of chemotherapy that are better tolerated by patients. We previously revealed that secreted protein acidic and rich in cysteine (SPARC), a matricellular protein, may function as a modulat...

A confounding aspect of biological ageing is the nature and role of senescent cells. It is unclear whether the three major types of cellular senescence, namely replicative senescence, oncogene-induced senescence and DNA damage-induced senescence are descriptions of the same phenomenon instigated by different sources, or if each of these is distinct, and how they are associated with ageing. Rece...
