Epitalon is an anti-aging agent and a telomerase activator. Epitalon has an inhibitory effect of the on the development of spontaneous tumors in mice, has geroprotective actions and intranasal administration increases neuronal activity. Epitalon can be used for cancer, old age and Retinitis Pigmentosa[1].
Addition of Epithalon peptide in telomerase-negative human fetal fibroblast culture induced expression of the catalytical subunit, enzymatic activity of telomerase, and telomere elongation, which can be due to reactivation of telomerase gene in somatic cells and indicates the possibility of prolonging life span of a cell population and of the whole organism[1].
Epitalon increases the lifespan of mice and fruit flies and restores the circadian rhythms of melatonin and cortisol production in old rhesus monkeys. At the same time, Epitalon prolongs the functional integrity of the eye retina in Campbell rats with hereditary Retinitis Pigmentosa and improves the visual functions in patients with pigmental retinal degeneration[1].

Epithalon decelerates aging and suppresses development of breast adenocarcinomas in transgenic her-2/neu mice
Bull Exp Biol Med 2002 Aug;134(2):187-90.PMID:12459848DOI:10.1023/a:1021104819170.
Female transgenic FVB/N mice carrying the breast cancer gene HER-2/neu received Epithalon (Ala-Glu-Asp-Gly) in a dose of 1 mg subcutaneously 5 times a week to from the 2nd month of life to death. Epithalon prolonged the average and maximum lifetimes of mice by 13.5 (p<0.05) and 13.9%, respectively. The peptide prolonged the average lifetime of animals without neoplasms (by 34.2%, p<0.05). Epithalon decelerated the development of age-related disturbances in reproductive activity and suppressed the formation of neoplasms. The peptide decreased the incidence of breast adenocarcinomas, lungs metastases (by 1.6 times, p<0.05), and multiple tumors (by 2 times). Epithalon 3.7-fold increased the number of mice without breast tumors (p<0.05), while the number of animals with 6 or more breast tumors decreased by 3 times (p<0.05). Epithalon prolonged the lifetime of mice with breast tumors by 1.4 times (p<0.05). These results indicate that Epithalon possesses geroprotective activity and inhibits breast carcinogenesis in transgenic mice, which is probably related to suppression of HER-2/neu expression.
Epithalon inhibits tumor growth and expression of HER-2/neu oncogene in breast tumors in transgenic mice characterized by accelerated aging
Bull Exp Biol Med 2002 Feb;133(2):167-70.PMID:12428286DOI:10.1023/a:1015555023692.
Female transgenic FVB mice carrying breast cancer gene HER-2/neu were monthly injected with Vilon or Epithalon (1 microgram subcutaneously for 5 consecutive days) starting from the 2nd month of life. Epithalon markedly inhibited neoplasm development: the maximum size of breast adenocarcinomas was 33% lower than in the control (p < 0.05). The intensity of HER-2/neu mRNA expression in breast tumors of Epithalon-treated mice was 3.7 times lower than in control animals. These results indicate that Epithalon inhibits breast tumor development in transgenic mice, which is probably related to suppression of HER-2/neu expression.
Studies of the effects of Vilon and Epithalon on gene expression in mouse heart using DNA-microarray technology
Bull Exp Biol Med 2002 Mar;133(3):293-9.PMID:12360356DOI:10.1023/a:1015859322630.
Expression of 15,247 clones from a cDNA library in the heart of mice receiving Vilon and Epithalon was studied by DNA-microarray technology. We revealed 300 clones (1.94% of the total count), whose expression changed more than by 2 times. Vilon changed expression of 36 clones, while Epithalon modulated expression of 98 clones. Combined treatment with Vilon and Epithalon changed expression of 144 clones. Vilon alone or in combination with Epithalon activated expression of 157 clones (maximally by 6.13 times) and inhibited expression of 23 clones (maximally by 2.79 times). Epithalon alone or in combination with Vilon activated expression of 194 clones (maximally by 6.61 times) and inhibited expression of 48 clones (maximally by 2.71 times). Our results demonstrate the specific effects of Epithalon and Vilon on gene expression.

Effect of Vilon and Epithalon on glucose and glycine absorption in various regions of small intestine in aged rats
Bull Exp Biol Med 2002 May;133(5):494-6.PMID:12420071DOI:10.1023/a:1019878224754.
Vilon (Lys-Glu) and Epithalon (Ala-Glu-Asp-Gly) administered orally for 1 month improved transport characteristics of the small intestine in aged rats. Vilon enhanced passive glucose accumulation in the serous fluid in inverted sac made from the distal region of the small intestine, while Epithalon enhanced this process in the medial region. Vilon stimulated active glucose accumulation in the serous sac of the medial small intestine, Epithalon - in the proximal and distal small intestinal segments. Glycine absorption increased only in the proximal intestinal segment under the effect of Epithalon.
