A synthetic tetrapeptide (Ala-Glu-Asp-Gly) derived from epithalamin, studied for its telomerase-activating, anti-aging, and pineal gland regulatory properties.
It was investigated the influence of polypeptide complex Pineamin on the 6-sulfatoxymelatonin (aMT6S) excretion in urine by ELISA test of 55 elderly patients with diminished melatoninsynthesis pineal gland function. Pineamin in course dose 100 mg has…
Exogenous short biologically active peptides epitalon (Ala-Glu-Asp-Gly), bronchogen (Ala-Glu-Asp-Leu), and vilon (Lys-Glu) at concentrations 10-10 M significantly influence growth, development, and differentiation of tobacco (Nicotiana tabacum) callu…
OsLEA1a is a late embryogenesis abundant (LEA) protein gene from Oryza sativa L, which contains an open reading frame of 282-bp that encodes a putative polypeptide of 93 amino acids. OsLEA1a protein contains abundant of Lys, Ala, Glu, Asp, Gly, Arg a…
Irisin produced by muscles during exercise and promoting fat burning also exhibits geroprotective effect and induces telomere elongation in normal somatic cells. Special attention is paid to studies of the role of peptides Lys-Glu, Glu-Asp-Arg, and A…
This review provides information about the structure and basic functions of the cytokine MIC-1/GDF15. MIC-1/GDF15 is normally contained not only in blood, but also expressed on cells of reproductive and nervous system. Its concentration increases in…
The article represents evidence about structures, properties and functions of adhesion molecule JAM-A/1 belonging to JAM subfamily. This protein plays an important role in epithelial tight junction formation and immune function. Current article focus…
We studied the effect of melatonin and epithalon on age-related changes in proteolytic digestive enzyme activity in the pancreas and gastric mucosa of rats kept under different lighting conditions. In rats kept under standard illumination, pepsin act…
The influence of the organospecific peptides--kidney tripeptides T-31 and T-35, pineal tetrapeptide epitalon on the main mechanisms of kidney injury caused by experimental rhabdomyolysis--toxic injury of tubular cells, development of oxidative stress…
Cytokines CCL11 (eotaxin) and HMGB1 (alarmin1) are molecular markers of ageing and neurological, cardiovascular and immune diseases. Created in St. Petersburg Institute of Bioregulation and Gerontology short peptides are known to regulate gene expres…
Judging from fluorescence modulation (quenching), short peptides (Ala-Glu-Asp-Gly, Glu-Asp-Arg, Ala-Glu-Asp-Leu, Lys-Glu-Asp-Gly, Ala-Glu-Asp-Arg, and Lys-Glu-Asp-Trp) bind with FITC-labeled wheat histones H1, H2B, H3, and H4. This results from the i…
Pulmonary tuberculosis is classified as a disease with a genetic predisposition, and therefore, as with other pathologies related to this group of diseases, by pulmonary tuberculosis, special importance is given to finding those markers that enable e…
Potential neuroprotective effects of the pineal gland hormone melatonin and peptide preparation epitalon on estrous cycles and the central regulation of reproduction in female rats exposed to unfavourable environmental factors have been studied. Estr…
Investigations were carried out on chicks of different age. It was found that the most pronounced changes in the morphology of the thymus occurred after neonatal hypophysectomy. These changes are least pronounced in old chicks. Peptides Lys-Glu-Asp-G…
In this paper, a comparative study of the functional genome indicators using lymphocyte cultures of patients with hypertrophic cardiomyopathy (HCM) and their first relatives. Studies conducted both in intact cultures and cultures exposed to the influ…
The review summarizes the results of long-term studies of the authors on the clinical efficacy of peptide bioregulators (Timalin, Thymogen, Vilon, Epithalamin, Prostatilen, Cortexin, Retinalamin) for the prevention of diseases and treatment of people…
Analysis of the main parameters of molecular mechanics (number of hydrogen bonds, hydrophobic and electrostatic interactions, DNA-peptide complex minimization energy) provided the data to validate the previously proposed qualitative models of peptide…
Catecholamines play an important role in the hypothalamic regulation of the synthesis and secretion of gonadotropin- releasing hormone, or gonadoliberin. We have shown that melatonin and the pineal gland peptides (epithalamine and epitalon) exert a c…
The effects of epithalone and vilone peptides on the synthesis of melatonin and factors involved in this process, arylalkylamine-N-acetyltransferase (AANAT) enzyme and pCREB transcription protein, were studied in rat pinealocyte culture. Epithalone s…
The review analyzed morphology, molecular and functional aspects of pineal gland aging and methods of it correction. The pineal gland is central organ, which regulates activity of neuroimmunoendocrine, antioxidant and other organisms systems. Functio…
