01
Mechanism of action
Research literature associates Epitalon with hTERT () upregulation in some normal cell lines, ALT-pathway activation in cancer cell lines, and modulation of neurogenic gene-expression markers (Nestin, GAP43, β-Tubulin III) in stem-cell models.
02
Research applications
- Telomere biology and cellular ageing research
- Gene regulation and neurogenic differentiation studies
- Short peptide comparison studies
03
Study references
Each profile cites a minimum of two peer-reviewed sources, with model type and reported sample size where the source provides it. Findings are model-specific and must not be extrapolated to therapeutic use.
AEDG Peptide (Epitalon) Stimulates Gene Expression and Protein Synthesis during Neurogenesis: Possible Epigenetic Mechanism
2020
Khavinson V et al. · Molecules
- Model
- In vitro — human gingival mesenchymal stem cells
- Sample
- Not reported in abstract
AEDG peptide was associated with increased expression of neurogenic differentiation markers (Nestin, GAP43, β-Tubulin III, Doublecortin) through proposed histone-interaction mechanisms.
Epitalon increases telomere length in human cell lines through telomerase upregulation or ALT activity
2025
Al-Dulaimi S et al. · Biogerontology
- Model
- In vitro — human breast-cancer cell lines (21NT, BT474), normal epithelial and fibroblast cell lines
- Sample
- Not reported in abstract
Reported concentration-dependent telomere lengthening via hTERT upregulation in normal cells and ALT pathway activation in cancer cell lines.
Overview of Epitalon — Highly Bioactive Pineal Tetrapeptide with Promising Properties
2025
Araj SK et al. · International Journal of Molecular Sciences
- Model
- Narrative review
- Sample
- N/A (review)
Reviewed 25 years of Epitalon research describing proposed antioxidant, neuroprotective, and antimutagenic activities across model systems.
Evidence caveats
- Much of the foundational rodent and human-observation literature comes from a single research group (Khavinson et al.); independent replication is limited.
- Anti-ageing and lifespan claims circulating outside the peer-reviewed literature are not supported by PubMed-indexed controlled human trials.
04
Storage and handling
Store under controlled laboratory conditions with batch and preparation details recorded.
- Record preparation conditions for short peptide comparison work.
- Protect material from contamination during handling.
- Use protocol-specific storage documentation.
