Growth hormone-releasing hormone (GHRH) antagonist MIA-690 and GHRH agonist MR-409, previously synthesized and developed by us have demonstrated potent antitumor effects. However, little is known about the effects of these analogs on brain functions.…
Ocular inflammation is a major cause of visual impairment attributed to dysregulation of the immune system. Previously, we have shown that the receptor for growth-hormone-releasing hormone (GHRH-R) affects multiple inflammatory processes. To clarify…
The extrahypothalamic growth hormone-releasing hormone (GHRH) and its cognate receptors (GHRH-Rs) and splice variants are expressed in a variety of cancers. It has been shown that the pituitary type of GHRH-R (pGHRH-R) mediates the inhibition of tumo…
Growth hormone-releasing hormone is a hypothalamic neuropeptide, which regulates the secretion of growth hormone by the anterior pituitary gland. Recent evidence suggest that it exerts growth factor activities in a diverse variety of in vivo and in v…
Growth hormone releasing hormone is a hypothalamic neuropeptide, which regulates the release of growth hormone from the anterior pituitary gland. Growth hormone releasing hormone antagonists are anticancer agents, associated with strong anti-inflamma…
To reverse the early-stage relapse post-hematopoietic stem cell transplantation, we investigated the safety and efficacy of a new epigenetic regimen (chidamide and decitabine plus thymalfasin simultaneously) on acute myeloid leukemia patients (exclud…
It was verified new molecular targets of geroprotective activity of AEDG (epitalon) and KE (vilon) peptides by the method of confocal laser scanning microscopy. It was shown that the MitoTracker Red mitochondries staining decreased and L7A ribosomal…
Night work provides biorhythms desynchronization, disorder of melatonin-producing function and accelerated pineal gland aging. One of the promising geroprotectors restoring the pineal melatonin synthesis is the AEDG (Ala-Glu-Asp-Gly) peptide. AEDG pe…
It was shown that AEDG peptide (Ala-Glu-Asp-Gly, Epitalon) regulates the function of the pineal gland, the retina, and the brain. AEDG peptide increases longevity in animals and decreases experimental cancerogenesis. AEDG peptide induces neuronal cel…
Primary stem cells, after several cell divisions, enter into a senescence state, that is characterized by alterations to spindle-shape typical morphology. This concern is one of the main problems in the use of human mesenchymal stem cells (hMSCs) in…
Stationary phase, especially methicillin-resistant(MRSA), has been widely associated with many persistent infections as well as biofilm-associated infections, which are challenging due to their increasing antibiotic resistance. α-Melanocyte stimulati…
Human melanocortin MC1 and MC3 receptors expressed on C-20/A4 chondrocytes exhibit chondroprotective and anti-inflammatory effects when activated by melanocortin peptides. Nearly 9 million people in the UK suffer from osteoarthritis, and bacterial in…
The EDR peptide (Glu-Asp-Arg) has been previously established to possess neuroprotective properties. It activates gene expression and synthesis of proteins, involved in maintaining the neuronal functional activity, and reduces the intensity of their…
Organic nanoparticles made out of biodegradable and biocompatible materials have attracted increased attention in the therapeutic and diagnostic fields. In this study, we attempted to explore a new radiolabelling chelating free strategy for biodegrad…
The effects of peptide ACTH4-7-PGP (Semax) were studied in 12 min after its intraperitoneal (in doses of 5, 15, 50, 150, and 450 μg/kg) or intracerebroventricular (in doses of 16, 40, and 400 pg) administration to rats with different types of pain an…
We studied the effect of Semax on the state of intestinal microbiota in rats subjected to restraint stress. Semax was injected to Wistar male rats intraperitoneally in doses of 5, 50, 150, 450 μg/kg 12-15 min before modelling chronic restraint stress…
Cerebral ischaemia is the most common cause of impaired brain function. Biologically active peptides represent potential drugs for reducing the damage that occurs after ischaemia. The synthetic melanocortin derivative, ACTHPGP (Semax), has been used…
We studied the effect of peptide drugs deltalicin and Semax on lipid metabolism disturbances in diabetes mellitus. Diabetes mellitus was modeled by single injection of streptozotocin (45 mg/kg) and rats with blood glucose ≥12 mmol/liter were selected…
Nonalcoholic fatty liver disease (NAFLD) is a common comorbidity among people living with HIV that has a more aggressive course than NAFLD among the general population. In a recent randomized placebo-controlled trial, we demonstrated that the growth…
Peptide ligation chemistry has revolutionized protein science by providing access to homogeneously modified peptides and proteins. However, lipidated polypeptides and integral membrane proteins-an important class of biomolecules-remain enormously cha…
