Ageing involves physiological decline and increased disease risk, potentially linked to programmed cell death (apoptosis). This review explores the obscure but emerging connection between ageing and apoptosis regulation in mammals.

Area of Science:

  • Gerontology
  • Cell Biology
  • Molecular Biology

Background:

  • Ageing is associated with physiological decline and increased incidence of diseases like cancer.
  • Alterations in programmed cell death (apoptosis) are hypothesized to contribute to age-associated changes.
  • The precise role of apoptosis in ageing and how ageing affects apoptosis regulation remains largely unknown.

Purpose of the Study:

  • To review the current understanding of the relationship between ageing and apoptosis.
  • To explore the potential cross-communication between ageing processes and apoptosis regulation in mammals.
  • To highlight the momentum and future directions in this research area.

Main Methods:

  • Literature review of existing research on ageing and apoptosis.

  • Analysis of studies in model organisms (e.g., C. elegans, D. melanogaster) and mammals.
  • Examination of conserved ageing regulatory systems, such as those affected by caloric restriction.

    • Main Results:

    • Molecules regulating apoptosis in mammals have been shown to influence ageing in simpler organisms.
    • Caloric restriction studies indicate conserved ageing regulatory systems across diverse species.
    • Despite strong suggestions, direct evidence for cross-communication between ageing and apoptosis in mammals is currently lacking.

    Conclusions:

    • A link between ageing and apoptosis is highly probable, with signals regulating ageing likely impacting apoptosis, and vice versa.
    • Further research is needed to elucidate the mechanisms of this cross-talk in mammalian systems.
    • Understanding the interplay between ageing and apoptosis is crucial for addressing age-related diseases.
