FOXO4

Product Introduction：

FOXO4 is a synthetic peptide derived from the forkhead box O (FOXO) family of transcription factors, with FOXO4-DRI (FOXO4-D-Retro-Inverso) being the most widely researched variant. This stable, water-soluble peptide has been extensively studied for its potential to target senescent cells, which are linked to aging and age-related degenerative conditions. FOXO4-DRI has shown promise in selectively inducing apoptosis in senescent cells while preserving healthy cells, supporting cellular rejuvenation, tissue repair, and overall longevity. It may also have anti-inflammatory, antioxidant, and metabolic regulatory properties. FOXO4 has been investigated for its potential to aid in the management of age-related conditions such as skin aging, muscle wasting, neurodegenerative disorders, and metabolic dysfunction. Requires reconstitution before use.

• How does FOXO4 work?

FOXO4 exerts its biological effects through multiple interconnected mechanisms centered on cellular senescence and stress response regulation.
• Senescent Cell Targeting: FOXO4, particularly the FOXO4-DRI variant, binds to the p53-FOXO4 interaction, selectively inducing apoptosis in senescent cells while sparing healthy, non-senescent cells. This targeted action disrupts the senescent cell burden, a key driver of aging and age-related decline.
• Stress Response & Antioxidant Activity: As a forkhead box O (FOXO) family transcription factor, FOXO4 modulates the expression of antioxidant and stress-responsive genes, enhancing cellular resilience to oxidative stress and DNA damage.
• Metabolic & Homeostatic Regulation: FOXO4 signaling influences metabolic pathways, including glucose and lipid metabolism, and regulates genes involved in cell cycle control, contributing to overall cellular and systemic homeostasis.

• Research

FOXO4 has emerged as a critical focus of aging and anti-aging research, with FOXO4-DRI showing robust preclinical potential in:
• Reversing age-related tissue dysfunction (e.g., skin, muscle, and neuronal tissue)
• Alleviating symptoms of neurodegenerative conditions by clearing senescent cells in the central nervous system
• Improving metabolic health by regulating insulin sensitivity and adipocyte function
• Investigating its role in extending healthspan and delaying the onset of age-related chronic diseases.

• Side Effects

Research on FOXO4 (FOXO4-DRI) is still in preclinical stages, and reported side effects in preclinical studies are limited. Potential mild, transient effects observed in animal models include:
• Fatigue
• Mild gastrointestinal discomfort (e.g., nausea, loose stools)
• Temporary changes in appetite
Note: No major adverse effects have been documented in controlled preclinical research; long-term side effects in humans remain to be fully elucidated in future clinical trials.
