• Folate Metabolism: Regulates one-carbon metabolism and nucleotide biosynthesis
• Insulin Sensitivity: Enhances glucose uptake and insulin signaling
• Mitochondrial Function: Improves mitochondrial efficiency and biogenesis
• Gene Expression: Translocates to the nucleus under stress to regulate metabolic genes

Humanin Mechanism

Humanin works through cellular protection pathways:

• STAT3 Activation: Activates the STAT3 signaling pathway for cell survival
• Anti-Apoptotic Effects: Inhibits cell death pathways (Bax, Bid)
• Neuroprotection: Protects neurons from Aβ toxicity and oxidative stress
• Insulin Signaling: Enhances insulin sensitivity in peripheral tissues
• Inflammation Reduction: Modulates inflammatory responses
