AI Summary
Humanin is a mitochondrial-derived peptide (MDP) encoded within the mitochondrial genome, comprising 24 amino acids. The evidence base is preclinical: laboratory and animal studies describe cytoprotective, anti-apoptotic, and metabolic effects, and reviews discuss it as a potential therapeutic target in age-related and degenerative diseases. Independent controlled human outcome trials are lacking, and it is not approved by any regulator. Effects are framed as studied in laboratory and animal models, not established in humans.
Key Information
Classification
Key Takeaways
- Humanin is a mitochondrial-derived 24-amino-acid peptide studied for cytoprotective and metabolic effects
- Evidence is from laboratory and animal models
- It is not approved by any regulator, and human treatment data are lacking
Scientific Overview
In Plain English
Humanin is a small peptide that cells make from mitochondrial DNA. Laboratory and animal studies suggest it may protect cells from stress and influence metabolism. It is being studied as a research target and is not an approved medicine; there are no controlled human treatment trials establishing benefit.
Scientific Details
Humanin is a 24-amino-acid mitochondrial-derived peptide first identified in the context of neuroprotection. Preclinical studies describe anti-apoptotic and cytoprotective signaling and effects on metabolic and stress-response pathways, and reviews propose roles in cancer, neurodegeneration, and age-related disease. The literature is predominantly preclinical, and controlled human outcome data are not available.
How It Works
Humanin is described in research as a cytoprotective mitochondrial-derived peptide associated with anti-apoptotic signaling and modulation of cellular stress responses and metabolism in laboratory and animal models. These mechanisms are characterized preclinically and are not confirmed by controlled human studies.
Mechanism of Action
Anti-apoptotic / cytoprotective signaling
cell
Cell and animal studies associate humanin with protection against apoptosis and cellular stress.
Metabolic modulation
animal
Preclinical work reports effects on metabolic and stress-response pathways relevant to age-related disease models.
Evidence Level
Human Evidence
Independent controlled human outcome trials are not available; humanin is studied as a research target rather than an established therapy.
Animal Evidence
Rodent studies describe cytoprotective and metabolic effects.
Cell Evidence
In vitro studies describe anti-apoptotic and stress-protective signaling.
Limitations
The literature is predominantly preclinical; there are no controlled human efficacy or safety trials, and it is not an approved medicine.
Why This Grade
Graded preclinical: cytoprotective and metabolic effects are described in cell and animal models only, without controlled human outcome data.
