Estetrol, molecular chaperones, and the epigenetics of longevity and cancer resistance

Area of Science:

• Gerontology
• Epigenetics
• Molecular Biology

Background:

• Replicative senescence and organismal aging are potentially linked to epigenetic phenomena.
• Molecular chaperones are crucial for cellular homeostasis, supporting protein folding, repair, and transport.
• Age-related decline in chaperone function may contribute to senescence and frailty.

Purpose of the Study:

• To review evidence on the role of molecular chaperones in aging and senescence.
• To explore the potential of estetrol as a therapeutic supplement for senescence.

Main Methods:

• Literature review of studies on senescence, aging, molecular chaperones, and estetrol.
• Analysis of the mechanisms by which chaperones maintain cellular homeostasis.
• Examination of estetrol's effects on chaperone function and cancer resistance.

Main Results:

• Evidence suggests senescence is an epigenetic process influenced by chaperone activity.
• Weakened chaperone defense is associated with increased frailty in senescence.
• Estetrol shows potential in promoting chaperone functions, homeostasis, and cancer resistance.

Conclusions:

• Estetrol may be a beneficial supplement for counteracting senescence in humans.
• Targeting chaperone function represents a potential strategy for mitigating age-related decline.
• Further research is warranted to validate estetrol's therapeutic role in aging populations.
