Cellular senescence is a state characterized by permanent cell-cycle arrest, increased expression of markers such as p16^INK4a and p21^CIP1/WAF1, elevated DNA damage signals (e.g., γ-H2AX) and a ...

There exists a complex synergistic relationship among cancer, circadian rhythms, and aging: aging is a major risk factor for cancer, disruption of circadian rhythms promotes tumor initiation and ...

After a finite number of divisions, cells simply give up. As each round of replication trims their telomeres—the protective caps at the chromosome ends—those caps eventually become too short to ...

T cell senescence occurs in the TME, affecting cancer prognosis and immunotherapy efficacy. The TME induces T cell senescence through multiple pathways, including persistent stimulation by ...

Markers of cellular aging -- such as DNA damage response, cellular senescence, and inflammatory pathways -- significantly increased in all breast cancer survivors, regardless of the type of treatment ...

Aging is a complex biological process characterized by the progressive decline of physiological integrity, leading to impaired function and increased vulnerability to disease. It is the strongest risk ...

There exists a complex synergistic relationship among cancer, circadian rhythms, and aging: aging is a major risk factor for cancer, disruption of circadian rhythms promotes tumor initiation and ...

A wearable light therapy device tuned to near-infrared wavelengths has reduced a key cellular aging marker by 92% in laboratory tests on human hair follicle cells, according to new research. The ...
