Abstract:
Here we summarize briefly what is known about both the positive and negative impacts of apoptosis during aging in mammalian systems and also update an earlier review. It is important to understand both of these impacts to devise useful interventions. Such interventions include both physiological and molecular approaches, including transgenic interventions. The critical roles of the mitochondria in both generating reactive oxygen species, and in initiating apoptosis are recognized, suggesting that maintaining mitochondrial function could be an important therapeutic goal, especially in post-mitotic tissues. In contrast, the ability to eliminate unwanted, damaged and dysfunctional cells through apoptosis has anti-aging implications in mitotic tissues.
Insights
Apoptosis, or programmed cell death, has dual roles in aging. Understanding its positive and negative impacts is key to developing interventions targeting mitochondrial function and cell elimination for longevity.
Area of Science:
- Gerontology and Cellular Biology
- Molecular mechanisms of aging
- Mammalian aging processes
Background:
- Apoptosis (programmed cell death) plays a complex role in mammalian aging.
- Previous reviews have highlighted the significance of apoptosis in aging.
- Understanding both beneficial and detrimental effects is crucial for therapeutic development.
Purpose of the Study:
- To summarize current knowledge on the positive and negative impacts of apoptosis in aging mammalian systems.
- To provide an updated review of apoptosis's role in aging.
- To identify potential therapeutic interventions based on apoptosis modulation.
Main Methods:
- Literature review and synthesis of existing research on apoptosis and aging.
- Analysis of physiological and molecular approaches for intervention.
- Consideration of transgenic interventions.
Main Results:
- Apoptosis has both beneficial and detrimental effects during aging.
- Mitochondria are critical in reactive oxygen species generation and apoptosis initiation.
- Maintaining mitochondrial function is a potential therapeutic goal, particularly in post-mitotic tissues.
- Apoptosis-mediated elimination of damaged cells has anti-aging implications in mitotic tissues.
Conclusions:
- Modulating apoptosis offers therapeutic potential for aging.
- Targeting mitochondrial function is a promising strategy for age-related interventions.
- Leveraging apoptosis for cellular clearance in mitotic tissues may promote longevity.

Overview of Cell Death
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the 20th century...
