Humanin

Also known as: HN

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.

Low Dose Ketamine Preconditions Astrocyte Mitochondria to Achieve Antidepressant Efficacy via Adenosine, Humanin, and Melatonin Upregulation and Efflux

Understanding the physiological changes induced by ketamine in mood disorders, while reducing its side effects, is likely to contribute to a more comprehensive understanding of the physiology underlying mood disorders, as well as to the development of faster-acting and more efficacious antidepressant treatments.

S14G-humanin attenuates renal ischaemia-reperfusion injury, potentially through activation of STAT3 and ERK1/2 signalling pathways in rats

Renal ischaemia-reperfusion (I/R) injury leads to acute tubular necrosis and renal failure, triggering pathological mechanisms including inflammation, reactive oxygen species generation, apoptosis and mitochondrial dysfunction.

Humanin ameliorates diabetes-induced testicular damage in a streptozotocin-induced mouse model

Diabetes mellitus is a major metabolic disorder closely associated with oxidative stress and male reproductive dysfunction.

Humanin peptide ameliorates reproductive dysfunction and restores neuroendocrine mechanisms in SSRI-treated male rats

Selective serotonin reuptake inhibitors (SSRIs) such as paroxetine frequently induce male sexual dysfunction by disrupting neuroendocrine balance and central dopaminergic pathways.

Mitochondrial-derived peptide Humanin protects granulosa cells under oxidative conditions

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.
