A synthetic tetrapeptide (Ala-Glu-Asp-Gly) derived from epithalamin, studied for its telomerase-activating, anti-aging, and pineal gland regulatory properties.
The combined craniocerebral trauma is accompanied by an impaired brain function in respect to regulating the entire organism and extends the neurohumoral processes of metabolism. The use of a bioregulator of the cytomedine class--epitalamin--is an ac…
Mitotic index of type B spermatogonia in intact animals is characterized by a circadian rhythm. Mitotic index increased and its circadian rhythm disappeared after pinealectomy. Treatment with Epithalamin for 14 days restored the circadian rhythm. The…
Effects of synthetic short peptides (Vilon, Epithalon, Livagen, Prostamax, and Cortagen) on activity of ribosome genes, parameters of common heterochromatin melting, polymorphism of structural heterochromatin (C segments) of chromosomes 1, 9, and 16,…
The review presents the results of experimental studies conducted by the author. CBA, SHR, HER-2/neu and SAM mice revealed inhibition of age-related alterations in estrus function and spontaneous tumour development and showed life span extension unde…
We studied the effect of Epithalon on the function of pancreatic islets and regulation of blood glucose level in female rhesus monkeys of various ages. Epithalon corrected the age-related decrease in glucose tolerance and restored the dynamics of ins…
The purpose of this study is to investigate possible influences of different stressors (saline injections, light deprivation and constant light regimen) and geroprotectors (Epitalon and melatonin) on survivals of female HER-2/neu transgenic mice. We…
Neonatal hypophysectomy in chicken, as well as that in old hen has been established to entail in 1,5 months after surgery cellular and humoral immunity disturbances, pronounced hypercoagulation and fibrinolysis depression. Administration of Epitalon…
It was investigated the influence of pineal peptides on the aging changes both circadian rhythm of thymic serum factor (FTS) titer in male rats Wistar and circannual rhythms of FTS, the amount of stromal cells-precurcors (CFC-F), granulocyte-macropha…
Investigation of the age-related changes of the pineal gland function and possible ways for their overcoming on nonhuman monkey model was the purpose of this study. Hormonal function of the pineal gland was studied in 38 Macaca mulatta females of two…
The role of the modulation of the pineal gland function in development of breast cancer is discussed in this review. An inhibition of the pineal function with pinealectomy or with the exposure to the constant light regimen stimulates mammary carcinog…
We studied the retinoprotective effect of Epithalon administered to the offspring of Campbell rats during postnatal ontogeny and to mothers before mating and during pregnancy. After this treatment the morphological structure and functional activity o…
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 somat…
We studied the effects of Retinalamin (polypeptide preparation isolated from the retina) and a synthetic peptide Epithalon (Ala-Glu-Asp-Gly) on proliferative activity of retinal and pigmented epithelial cells. Experiments showed that Retinalamin and…
The effect of new peptide bioregulators--Livagen (Lys-Glu-Asp-Ala) and Epitalon (Ala-Glu-Asp-Gly)--on endogenous opioid system was studied, particularly, their ability to change the activity of enkephalin-degrading enzymes from serum and interact wit…
The effect of the synthetic pineal peptide Epitalon (Ala-Glu-Asp-Gly) on proliferative activity in colon tumors, and in mucosal epithelial cells adjacent to and located far from tumors was studied in rats. To evaluate the effect of Epitalon on differ…
From the age of 3 months until their natural deaths, female outbred Swiss-derived SHR mice were subcutaneously injected on 5 consecutive days every month with 0.1 ml of normal saline (control) or with 1.0 microg/mouse (approximately 30-40 microg/kg)…
Gateways to Clinical Trials is a guide to the most recent clinical trials in current literature and congresses. The data in the following tables has been retrieved from the Clinical Studies Knowledge Area of Prous Science Integrity, the drug discover…
UNLABELLED: OBJECTIVES and design. We have studied the effect of synthetic peptide Epitalon on the activity of ribosomal genes, denaturation parameters of total heterochromatin, polymorphism of structural C-heterochromatin and the variability of facu…
Experimental studies of geroprotective activity of synthetic oligopeptides and conformational analysis of the tetrapeptide Epithalon allowed us to hypothesize that regulatory oligopeptides directly initiate transcription of genes for vitally importan…
Studies were undertaken on the development of T-lymphocytes in adult and old CBA mice and its changes at aging after injections of pineal gland peptides. It was shown that in old mice the disturbances of T-cells differentiation are registered in bone…
