Decreased growth hormone (GH) and insulin-like growth factor 1 (IGF-1) activity, known as somatopause, is linked to aging. Inhibiting GH action may extend lifespan and protect against age-related diseases.
Area of Science:
- Endocrinology
- Gerontology
- Genetics
Background:
- Growth hormone (GH) and insulin-like growth factor 1 (IGF-1) levels decline with age, a process termed somatopause.
- Recombinant human GH is misused as an anti-aging treatment despite lacking efficacy.
- Mutations reducing GH/IGF-1 axis activity extend lifespan in mice.
Purpose of the Study:
- To review the effects of altered GH/IGF-1 axis activity on lifespan in mice and humans.
- To explore the potential of inhibiting GH action as an anti-aging strategy.
- To describe the mechanisms, benefits, and risks of medically disrupting the GH/IGF-1 axis.
Main Methods:
- Review of data from mouse strains with genetic alterations in the GH/IGF-1 axis.
- Analysis of human genetic studies on mutations affecting the GH/IGF-1 axis.
- Examination of existing literature on the physiological effects of GH/IGF-1 axis modulation.
Main Results:
- Reduced GH/IGF-1 axis activity is associated with extended longevity in mice.
- Mice and humans with diminished GH/IGF-1 activity show protection against cancer and diabetes.
- Human data on the longevity effects of corresponding mutations are still under investigation.
Conclusions:
- Pharmaceutical inhibition of GH action may offer a novel approach to delay aging.
- Targeting the GH/IGF-1 axis presents potential therapeutic benefits for age-related diseases.
- Further research is needed to establish the safety and efficacy of disrupting the GH/IGF-1 axis in humans.
