Humanin

aka HN

Growth Hormone Secretagogues

Mechanism

Humanin is a mitochondrial-derived peptide encoded within the 16S ribosomal RNA gene. It was discovered through its ability to protect neurons from Alzheimer's disease-related toxicity and is studied for neuroprotection, metabolic regulation, and anti-aging applications.

Mitochondrial-derived peptide Humanin protects granulosa cells under oxidative conditions
Conte JG, Reynoso S, Gosso MS, Sánchez Rojas IA, Romero AC, Magnani ND, Jaita G. · Reproduction (Cambridge, England) (2026) ·

In brief: Redox imbalance compromises granulosa cell survival and follicle fate. This study identifies the mitochondrial-derived peptide Humanin (HN) as a cytoprotective factor that protects granulosa cells under oxidative condItions. Abstract: Granulosa cell function is essential for proper ovarian physiology.
