The aim of this work was to study the delayed effects of chronic neonatal administration of the selective serotonin reuptake inhibitor fluvoxamine (FA) to white rat pups and to estimate the possibility to correct these effects by treatment with semax…
The influence two original derivatives of a therapeutically important peptide, bearing arachidonic acid residue with semax and proglyprol, upon platelet aggregation have been studied in vitro. It is established that both derivatives, in contrast to t…
BACKGROUND: The nootropic neuroprotective peptide Semax (Met-Glu-His-Phe-Pro-Gly-Pro) has proved efficient in the therapy of brain stroke; however, the molecular mechanisms underlying its action remain obscure. Our genome-wide study was designed to i…
IMPORTANCE: Among patients infected with human immunodeficiency virus (HIV), visceral adiposity is associated with metabolic dysregulation and ectopic fat accumulation. Tesamorelin, a growth hormone-releasing hormone analog, specifically targets visc…
CONTEXT: Few studies have assessed the relationship between GH and mitochondrial function. OBJECTIVE: The objective of this study was to determine the effects of improving IGF-I using a GHRH analog, tesamorelin, on mitochondrial function assessed by…
Objective. To study the efficacy and tolerability of the new anxyolytic peptide selank in comparison with phenazepam. Material and methods. A comparative study of the anxiolytic effect and tolerability of selank and phenazepam was carried out in 60 p…
We studied the effects of selank on the development of symptoms of acute 48-h alcohol withdrawal in outbred rats drinking 10 % ethanol as the only source of fluid for 24 weeks. In alcohol-preferring animals (mean daily ethanol intake >5.0 g/kg) allow…
Previous studies have shown that synthetic tuftsin analogue Selank and its fragments cause a number of alterations in the expression of certain genes involved in inflammation in mouse spleen. In this work we studied the effect of Selank and its short…
Biologically active regulatory peptide, tripeptide Pro-Gly-Pro (PGP) was used as C-terminal fragment for peptide drugs Semax and Selank. In recent years the independent effects of PGP were observed. The question was raised, whether PGP contributes to…
INTRODUCTION: Over the last 20 years, basic and clinical research activities studying the male and female sexual responses have led to several pharmacological options to treat male erectile dysfunction (ED) and female arousal and orgasmic disorders.…
Thymosin β4 (Tβ4) is a highly conserved peptide with immunomodulatory properties. In this research we investigated the effects of Tβ4 on the bleomycin-induced lung damage in CD-1 mice and the changes in the number of IL-17-producing cells as well as…
Recent studies have shown that thymosin β4 (Tβ4) stimulates angiogenesis by inducing vascular endothelial growth factor (VEGF) expression and stabilizing hypoxia inducible factor-1α (HIF-1α) protein. Pulmonary tuberculosis (TB), a type of granulomato…
F-actin treadmilling plays a key part in cell locomotion. Because immunofluorescence showed colocalisation of thymosin beta4 (Tβ4) with cofilin-1 and Arp2/3 complex in lamellipodia, we analyzed combinations of these proteins on F-actin-adenosine trip…
Thymosin beta 4 is a pleiotropic actin-sequestering polypeptide that is involved in wound healing and developmental processes. Thymosin beta 4 gene silencing promotes differentiation of neural stem cells whereas thymosin beta 4 overexpression initiat…
Previous studies have shown that the recombination of cells liberated from developing tooth germs develop into teeth. However, it is difficult to use human developing tooth germ as a source of cells because of ethical issues. Previous studies have re…
Beta-thymosins constitute a group of small actin-sequestering peptides. These highly conserved peptides are involved in cytoskeleton dynamics and can influence different cell properties such as motility, substrate adhesion, shape and chemotaxis. As a…
Thymosin β4 (Tβ4 ) is a regenerative peptide that we hypothesized would promote healing of fractured bone. Mice received a bilateral fibular osteotomy and were given i.p. injections of either Tβ4 (6 mg/kg) or saline. Calluses from saline- and Tβ4 -tr…
Thymosin-β4 (Tβ4) promotes cell survival, angiogenesis, and tissue regeneration and reduces inflammation. Cardiac rupture after myocardial infarction (MI) is mainly the consequence of excessive regional inflammation, whereas cardiac dysfunction after…
