Aging and endothelin: determinants of disease

Area of Science:

• Gerontology
• Molecular Biology
• Cardiovascular Research

Background:

• Increased human life expectancy presents healthcare challenges.
• Cellular senescence, a pro-inflammatory state, links aging and chronic diseases.
• Modifiable molecular mediators (MMMs) offer targets for healthy aging interventions.

Purpose of the Study:

• To review the molecular regulation of endothelin-1 (ET-1).
• To explore ET-1's role in vascular homeostasis, aging, and cellular senescence.
• To discuss clinical implications of ET-1 overproduction and interventions for healthy aging.

Main Methods:

• Review of preclinical studies on ET-1 targeting.
• Analysis of ET-1's role in aging-associated cellular changes.
• Discussion of therapeutic strategies including ERAs, ARBs, ACEIs, and physical activity.

Main Results:

• ET-1, a multifunctional peptide, promotes disease when overproduced, primarily via ETA receptor activation.
• Preclinical studies indicate partial regression of aging-associated vascular and kidney changes by targeting ET-1.
• Modulation of ET-1 activity or production is a viable strategy for healthy aging.

Conclusions:

• ET-1 is a critical target for mitigating aging-related diseases.
• Interventions targeting ET-1 can potentially reverse cellular senescence and promote vascular health.
• Promoting healthy aging involves managing ET-1 pathways and lifestyle factors like physical activity.
