European review for medical and pharmacological sciences·2019

Ageing causes organ systems to decline, reducing stress resilience. This review summarizes current knowledge on the molecular mechanisms driving cellular degeneration and loss of regeneration during the ageing process.

Area of Science:

Gerontology
Molecular Biology
Cellular Biology

Background:

Ageing is a natural process marked by declining organ function and reduced homeostasis.
Cellular degeneration and impaired regenerative capacity increase with age.
These age-related changes contribute to organismal decline and eventual death.

Purpose of the Study:

To summarize current scientific understanding of the molecular mechanisms underlying ageing.
To provide an overview of age-related cellular and functional changes.

Main Methods:

Review of existing literature on ageing mechanisms.
Analysis of molecular biology and cell culture techniques applied to ageing research.

Main Results:

Related Experiment Videos

Ageing involves progressive cellular degeneration.
Regenerative capacity diminishes over time.
Accumulated molecular alterations drive the ageing phenotype.

Conclusions:

Understanding molecular ageing mechanisms is crucial for addressing age-related decline.
Cellular and molecular factors play a significant role in the ageing process.
