Abstract:
Cellular senescence (CS) is a state of stable cell cycle arrest characterized by the production and secretion of inflammatory molecules. Early studies described oncogene-induced senescence (OIS) as a barrier to tumorigenesis, such that the therapeutic induction of CS might represent a rational anti-cancer strategy. Indeed, the validity of this approach has been borne out by the development and approval of the cyclin-dependent kinase (CDK) inhibitor palbociclib for the treatment of breast cancer. Apart from tumors, senescent cells have also been shown to accumulate during natural mammalian aging, where they produce detrimental effects on the physiology of surrounding tissues. Thus, pharmacological senescent cell depletion has been proposed as an approach to delay age-related functional decline; this has been formally demonstrated in animal models. In this review article, we describe the current mechanistic understanding of cellular senescence at the molecular level and how it informs the development of new therapeutic strategies to combat cancer and aging.
Insights
Cellular senescence, a cell cycle arrest state, offers anti-cancer potential and may delay aging. Therapies targeting senescent cells show promise for treating cancer and age-related diseases.
Area of Science:
- Molecular Biology
- Gerontology
- Oncology
Background:
- Cellular senescence (CS) is a stable cell cycle arrest linked to inflammation.
- Oncogene-induced senescence (OIS) acts as a tumor suppressor.
- Senescent cells accumulate with age, negatively impacting tissue physiology.
Purpose of the Study:
- To review the molecular mechanisms of cellular senescence.
- To explore therapeutic strategies targeting senescence for cancer and aging.
Main Methods:
- Review of existing literature on cellular senescence.
- Analysis of molecular pathways involved in senescence.
- Examination of therapeutic interventions for senescence.
Main Results:
- Cellular senescence can be therapeutically induced to combat cancer, as exemplified by CDK inhibitor palbociclib.
- Pharmacological depletion of senescent cells shows potential in animal models for delaying age-related decline.
- Understanding senescence mechanisms is key to developing novel treatments.
Conclusions:
- Cellular senescence is a critical target for both anti-cancer therapies and interventions aimed at mitigating age-related diseases.
- Further research into the molecular underpinnings of senescence will drive the development of innovative therapeutic strategies.
