Epithalon Telomerase, longevity and anti-aging research — A scientific guide

Origin and history of research on the Epithalon

Epithalon was synthesized and studied from the 1980s by Professor Vladimir Khavinson and his team at the Institute of Gerontology in Saint Petersburg (Russia), as part of research on regulatory peptides of the pineal gland (epiphysis) and the immune system.

Its name derives fromepithalamusThe brain region that encompasses the pineal gland. The parent molecule of the epithalon is...Epithalamine, a crude polypeptide extract of the bovine pineal gland. Epithalon is the minimal active synthetic tetrapeptide isolated from this preparation.

Mechanism of action: telomerase activation

Telomeres and cellular aging

THE telomeres Telomeres are repeated DNA sequences (TTAGGG) that cap the ends of chromosomes, protecting them from degradation during cell division. With each division, telomeres shorten slightly. When they reach a critical length, the cell enters senescence (cessation of division) or in apoptosis (programmed cell death).

La telomerase (TERT enzyme + TERC template RNA) is the enzyme capable of lengthening telomeres by adding new repetitive sequences. It is active in stem cells and germ cells, but almost absent in most differentiated somatic cells.

How Epithalon acts on telomerase

Studies published by Khavinson et al. (2003, 2004) have shown that the Epithalon:

• Activates gene expression TERT (telomerase catalytic subunit) in cultured human fibroblasts
• Increases telomere length in human cells after several passages in culture
• Delays cellular senescence (increases the number of passages before senescence)
• Reduces senescence markers (β-galactosidase SA) in aging fibroblasts

Studies on longevity in animals

Experiments on the mouse

Studies in SAM (Senescence-Accelerated Mice, a model of accelerated aging) mice have shown:

• Increased lifespan of 20-30% compared to controls in some experiments
• Reduction in the incidence of mammary tumors in female mice
• Improvement in immunological parameters with age (maintained lymphocyte proliferation)

Experiments with monkeys (very limited studies)

Exploratory studies on non-human primates (macaques) have shown an improvement in some hormonal and immunological parameters, but the data remain very preliminary.

Effects on other biological systems

Pineal gland and melatonin

Epithalon appears to activate the pineal gland and increase melatonin secretion in some preclinical models. Melatonin is a potent antioxidant and circadian regulator, and its production declines with age. This pineal-epithalon connection is one of the most active avenues of research.

Effects on the immune system

Data suggests that Epithalon can:

• Improving T-cell proliferation with age
• Modulating cytokine production (IL-2, IFN-γ)
• Reducing certain markers of low-grade chronic inflammation (inflamm-aging)

Anti-tumor effects (preclinical models)

Studies in mouse models of breast, colon, and cervical cancer have shown a reduction in tumor incidence and a slowing of tumor growth with Epithalon. The proposed mechanisms include immunostimulation and normalization of the cellular biological clock.

Epithalon and GHK-Cu: association in gerontological research

In aging research protocols, Epithalon is often studied in combination with GHK-Cu:

• Epithalon: action on telomeres and cell division
• GHK-Cu: action on DNA repair, collagen synthesis and inflammation

These two peptides have complementary mechanisms on different aspects of cellular aging, which explains their frequent association in experimental gerontology studies.
