A synthetic tetrapeptide (Ala-Glu-Asp-Gly) derived from epithalamin, studied for its telomerase-activating, anti-aging, and pineal gland regulatory properties.
OBJECTIVES AND DESIGN: Researchers of the St. Petersburg Institute of Bioregulation and Gerontology of the North-Western Branch of the Russian Academy of Medical Sciences and the Institute of Gerontology of the Ukrainian Academy of Medical Sciences (…
Translocation of cytomedins into the cell is determined by their interaction with cellular membranes. The investigation concerned membrane-associated free-radical reactions in the formed elements of blood incubated with epithalamin. The antioxidative…
The pineal gland contains many peptides known to be implicated in melatonin production. We examined the effects of a synthetic pineal tetrapeptide Ala-Glu-Asp-Gly on melatonin secretion by the pineal gland. The tetrapeptide effects on pineal gland me…
The treatment effect and clinical efficacy of epithalamine solution was studied on 28 patients (42 eyes) with unstable glaucoma and normalized intraocular pressure (IOP). Epithalamine belongs to the group of cytomedines and it has a modeling effect o…
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 dist…
A technology has been developed for manufacturing of biologically active complex peptide preparations from extracts of different tissues. In particular, the pineal preparation (Epithalamin) augments the in vitro outgrowth of explants from the pineal…
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 chang…
Peroral administration of Epithalon (Ala-Glu-Asp-Gly) to male and female Wistar rats aging 3 and 11 months changed activity of enzymes hydrolyzing carbohydrates, proteins, and phosphoric acid esters in various portions of the gastrointestinal tract.…
The incidence of chromosome aberrations in bone marrow cells of 12-month-old SAMP-1 female mice characterized by accelerated aging was 1.8 times higher than in wild-type SAMR-1 females and 2.2 times higher than in SHR females of the same age. Treatme…
The peculiarities of the differentiation of the thymocytes in adult and old CBA/Ca mice were studied with a help of the monoclonal antibodies to different lymphoid antigens of mice. In the thymus of old mice, the portions of the CD4-CD8-, CD44+ and C…
Female FVB/N HER-2/neu transgenic mice from the age of 2 months were subcutaneously injected with saline, the peptide Epitalon(R) (Ala-Glu-Asp-Gly) or with the peptide Vilon(R) (Lys-Glu) in a single dose of 1 microg/mouse for 5 consecutive days every…
We have studied the effect of tetrapeptide Epitalon (Ala-Glu-Asp-Gly) on the course of congenital pigmented degeneration of the retina. The application of Epitalon in Campbell rats is found to intensify the bioelectric and functional activity of the…
The effect of peptide bioregulator Epithalon on the course of hereditary pigmentary retinal degeneration was studied in Campbell rats. Administration of epithalon starting from birth protected morphological structure, increased its bioelectrical acti…
Researchers of the St. Petersburg Institute of Bioregulation and Gerontology of the North-Western Branch of the Russian Academy of Medical Sciences and the Research Institute of Gerontology of the Ukrainian Academy of Medical Sciences (Kiev) clinical…
Available clinical data on aspirin-sensitive asthma (ASA) indicate that ASA patients have certain disturbances in the nervous, endocrine, immune and other body systems. It has been found that such patients have a lower melatonin (MT) production in da…
The effect of synthetic pineal peptide Epitalon (Ala-Glu-Asp-Gly) on colon carcinogenesis was firstly studied in rats. Eighty 2-month-old outbred male LIO rats were subdivided into four groups and were weekly exposed to five subcutaneous injections o…
The age-related changes in the pineal gland are functional rather than organic, which makes their correction or prevention more tenable. The amelioration or inhibition of some age-related impairments of the pineal gland were observed with dietary res…
There was studied the effect of polypeptide preparations isolated from the cerebral cortex (Cortexin), epiphysis (Epithalamin), liver (Hepalin), thymus (Thymalin) and small synthetic peptides--Cortagen, Epitalon, Livagen, Vilon on the development of…
Effects of peptide bioregulators (thymaline, epithalamine, cortexine) on systemic hemodynamics in cardiovascular and cerebrovascular affections were studied. Assessment of functional stability and quality of cardiovascular system regulation was made…
