Overview of Celiac Disease in Russia: Regional Data and Estimated Prevalence (публикация автора на scipeople)     

Замятнин А. А. (директор); Шария М.А. (профессор); Несвижский Юрий Владимирович (профессор) , 2018
Celiac disease (CD) is an autoimmune enteropathy triggered by the ingestion of dietary gluten from some cereals mainly in individuals carrying the HLA-DQ2 and/or HLA-DQ8 haplotypes. As an autoimmune disease, CD is manifested in the small intestine in the form of a progressive and reversible inflammatory lesion due to immune response to self-antigens. Indeed, CD is one of the most challenging medicosocial problems in current gastroenterology. At present, the global CD prevalence is estimated at approximately 1% based on data sent from different locations and available CD screening strategies used. However, it is impossible to estimate global CD prevalence without all the data from the world, including Russia. In this review, we summarize the data on the incidence and prevalence of CD across geographically distinct regions of Russia, which are mostly present in local Russian scientific sources. Our conclusion is that the situation of CD prevalence in Russia is higher than is commonly believed and follows global tendencies that correspond to the epidemiologic situation in Europe, America, and Southwest Asia.

Тарасов В. В. (директор); Маргарян Э.Г. (доцент); Несвижский Юрий Владимирович (профессор , 2018
Diet is an essential factor affecting the development of and risk for diabetes mellitus. In search of preventative and therapeutic strategies, it is to be considering the potential role of certain foods and their bioactive compounds to prevent the pathogenesis associated with metabolic diseases. Human consumption of anthocyanins is among the highest of all flavonoids. Epidemiological studies have suggested that the consumption of anthocyanins lowers the risk of diabetes and diabetic complications. Anthocyanins are important natural bioactive pigments responsible for red to blue colour of fruits, leaves, seeds, stems and flowers, which are present in a variety of plant species particularly in berries and cherries. A large number of bioactive anthocyanins, such as cyanidin, malvidin, delphinidin, pelargonidin, peonidin, petunidin and their metabolites have shown multiple biological activities with apparent effects on glucose absorption, glucose uptake, insulin secretion and sensitivity, on the enzymes involved in glucose metabolism, gene expressions, inflammatory mediators, glucose transporters in progression of diabetes and associated complications, such as diabetic retinopathy, nephropathy, neuropathy and diabetic vascular diseases. The versatility of the anthocyanins provides a promising approach for diabetes management than synthetic drugs. Here we summarize effect of several anthocyanins on many in vitro, in vivo and clinical studies and also reveals the mechanisms which could prevent or reverse the underlying mechanisms of diabetic pathologies including promotion of antioxidant, anti-hyperlipidemic, anti-inflammatory and anti-apoptotic activities.

Тарасов В. В. (директор); Чубарев Владимир Николаевич (профессор); Несвижский Юрий Владимирович (профессор) , 2018
Anthocyanins, a flavonoid class of polyphenols, are water soluble dark colored natural pigments found in fruits and vegetables. Owing to their wide distribution in plant materials, dietary consumption of anthocyanins is high compared to other flavonoids. Anthocyanins, due to their multifaceted medicinal properties are the active components in many herbal folk medicines. As in vitro and in vivo results, animal models, and clinical trials in various cell lines suggest, anthocyanins possess antioxidant, antidiabetic, antihyperlipidemic, anti-inflammatory, anticarcinogenic, antiulcer, and preventive activities against cardiovascular diseases. Additionally, anthocyanins exhibit chemotherapeutic, cardioprotective, hepatoprotective, and neuroprotective activities. In the diet, anthocyanins are absorbed in the stomach and intestinal cells and rapidly detected in the plasma. These promising properties of anthocyanins may well provide health benefits against chronic diseases.

Тарасов В. В. (директор); Чубарев Владимир Николаевич (профессор); Несвижский Юрий Владимирович (профессор) , 2018
Urotensin II (UT II) is an important factor of cellular homeostasis. This regulatory peptide is involved in the pathophysiology of many disorders. For example, it plays an important role in the pathogenesis of acute and chronic diseases, stressful and adaptive reactions of the body, in the development of cardiovascular pathologies, metabolic syndrome, inflammation, liver cirrhosis, renal failure, diabetic nephropathy, reproductive dysfunction, progression of psychosomatic, psychoendocrinal and psychiatric disorders. In this concern, the involvement of UT II in the pathophysiology of many processes determines the perspectives for the development of blockers of urotensin receptors for the treatment of the aforementioned diseases. It is important that even today this kind of perspective is feasible due to the synthesis of a series of GPR14 blockers. The objective of this review is to discuss current molecular mechanisms of biological activity, regulatory functions of UT II, its role in the pathogenesis of different nosologies, as well as analysis of the possible routes of exposure to GPR14 as potential therapeutic targets.

Тарасов В. В. (директор); Чубарев Владимир Николаевич (профессор); Несвижский Юрий Владимирович (профессор) , 2018
Background: Helicobacter pylori is associated with inflammation of different areas, such as the duodenum and stomach, causing gastritis and gastric ulcers leading to lymphoma and cancer. Pathogenic islands are a type of clustered mobile elements ranging from 10-200 Kb contributing to the virulence of the respective pathogen coding for one or more virulence factors. Virulence factors are molecules expressed and secreted by pathogen and are responsible for causing disease in the host. Bacterial genes/virulence factors of the pathogenic islands represent a promising source for identifying novel drug targets. Objective: The study aimed at identifying novel drug targets from pathogenic islands in H. pylori. Material & Methods: The genome of 23 H. pylori strains were screened for pathogenic islands and bacterial genes/virulence factors to identify drug targets. Protein-protein interactions of drug targets were predicted for identifying interacting partners. Further, host-pathogen interactions of interacting partners were predicted to identify important molecules which are closely associated with gastric cancer. Results: Screening the genome of 23 H. pylori strains revealed 642 bacterial genes/virulence factors in 31 pathogenic islands. Further analysis identified 101 genes which were non-homologous to human and essential for the survival of the pathogen, among them 31 are potential drug targets. Proteinprotein interactions for 31 drug targets predicted 609 interacting partners. Predicted interacting partners were further subjected to host-pathogen interactions leading to identification of important molecules like TNF receptor associated factor 6, (TRAF6) and MAPKKK7 which are closely associated with gastric cancer. Conclusion: These provocative studies enabled us to identify important molecules in H. pylori and their counter interacting molecules in the host leading to gastric cancer and also a pool of novel drug targets for therapeutic intervention of gastric cancer.

Тарасов В. В. (директор); Чубарев Владимир Николаевич (профессор); Несвижский Юрий Владимирович (профессор) , 2018
A new series of phenolic glycoside esters, saccharumoside-B and its analogs (9b-9n, 10) have been synthesized by the Koenigs-Knorr reaction. Antiproliferative activities of the compounds (9b-9n, 10) were evaluated on various cancer cell lines including, MCF-7 breast, HL-60 leukemia, MIA PaCa-2 pancreatic, DU145 prostate, HeLa cervical and CaCo-2 colon, as well as normal human MCF10A mammary epithelial and human peripheral blood mononuclear cells (PBMC) by MTT assay. Compounds (9b-9n, 10) exhibited considerable antiproliferative effects against cancer cells with IC50 range of 4.43 ± 0.35 to 49.63 ± 3.59 µM, but they are less cytotoxic on normal cells (IC50 > 100 µM). Among all the compounds, 9f showed substantial antiproliferative activity against MCF-7 and HL-60 cells with IC50 of 6.13 ± 0.64 and 4.43 ± 0.35, respectively. Further mechanistic studies of 9f were carried out on MCF-7 and HL-60 cell lines. 9f caused arrest of cell cycle of MCF-7 and HL-60 cells at G0/G1 phase. Apoptotic population elevation, mitochondrial membrane potential loss, increase of cytosolic cytochrome c and Bax levels, decrease of Bcl-2 levels and enhanced caspases-9 and -3 activities were observed in 9f-treated MCF-7 and HL-60 cells. These results demonstrate anticancer and apoptosis-inducing potentials of 9f in MCF-7 and HL-60 cells via intrinsic pathway.

Тарасов В. В. (директор); Чубарев Владимир Николаевич (профессор); Несвижский Юрий Владимирович (профессор) , 2018
Background: Anti-tumor effect of hydroxamic acid derivatives is largely connected with its properties as efficient inhibitors of histone deacetylases, and other metalloenzymes involved in carcinogenesis. Objective: The work was aimed to (i) determine the anti-tumor and chemosensitizing activity of the novel racemic spirocyclic hydroxamic acids using experimental drug sensitive leukemia P388 of mice, and (ii) determine the structure-activity relationships as metal chelating and HDAC inhibitory agents. Method: Outbreed male rat of 200-220 g weights were used in biochemical experiments. In vivo experiments were performed using the BDF1 hybrid male mice of 22-24 g weight. Lipid peroxidation, Fe (II) -chelating activity, HDAC fluorescent activity, anti-tumor and anti-metastatic activity, acute toxicity techniques were used in this study. Results: Chemosensitizing properties of water soluble cyclic hydroxamic acids (CHA) are evaluated using in vitro activities and in vivo methods and found significant results. These compounds possess iron (II) chelating properties, and slightly inhibit lipid peroxidation. CHA prepared from triacetonamine (1a-e) are more effective Fe (II) ions cheaters, as compared to CHA prepared from 1- methylpiperidone (2a-e). The histone deacetylase (HDAC) inhibitory activity, lipophilicity and acute toxicity were influenced by the length amino acids (size) (Glycine < Alanine < Valine < Leucine < Phenylalanine). All compounds bearing spiro-N-methylpiperidine ring (2a-e) are non-toxic up to 1250 mg/kg dose, while compounds bearing spiro-tetramethylpiperidine ring (1a-e) exhibit moderate toxicity which increases with increasing lipophility, but not excite at 400 mg/kg. Conclusion: It was shown that the use of combination of non-toxic doses of cisplatin (cPt) or cyclophosphamide with CHA in most cases result in the appearance of a considerable anti-tumor effect of cytostatics. The highest chemosensitizing activity with respect to leukemia Р388 is demonstrated by the CHA derivatives of Valine 1c or 2c.

Approaches of the Transcriptomic Analysis in Astrocytes: Potential Pharmacological Targets (публикация автора на scipeople)     

Тарасов В. В. (директор); Чубарев Владимир Николаевич (профессор); Несвижский Юрий Владимирович (профессор) , 2018
Astrocytes are important glial cells involved in the ionic regulation of the extracellular fluid in the Central Nervous System (CNS), the formation of the blood brain barrier (BBB) and the support to neurons for the maintenance of the Krebs cycle intermediaries. Even though these cells are known to be important for the brain functioning, several of their functions and their development have not been fully elucidated. In this context, identifying the algorithms used for their analysis plays a pivotal role in the development of new strategies in the study of astrocytes. The main objective of this review is to summarize the techniques that have helped to obtain transcriptomic data in astrocytes and the new algorithms that were used to perform the analysis of experimental data, elucidating new studies in which these had been used. We also highlight the current transcriptomics approaches targeting astrocytes function as a possible target for pharmacological interventions.

Pharmacological Aspects of Neuro-Immune Interactions (публикация автора на scipeople)     

Тарасов В. В. (директор); Чубарев В.Н. (профессор); Несвижский Юрий Владимирович (профессор) , 2018
The use of systematic approach for the analysis of mechanism of action of drugs at different levels of biological organization of organisms is an important task in experimental and clinical pharmacology for drug designing and increasing the efficacy and safety of drugs. The analysis of published data on pharmacological effects of psychotropic drugs possessing immunomodulatory and/or antiviral properties have shown a correlation between central effects of examined drugs associated with the impact on the processes of neurogenesis of adult brain and survival of neurons, and their ability to alter levels of key proinflammatory cytokines. The changes that occur as a result of the influence of pharmacological agents at one of the systems should inevitably lead to the functional reorganization at another. Integrative mechanisms underlying the neuro-immune interactions may explain the "pleiotropic" pharmacological effects of some antiviral and immunomodulatory drugs. Amantadine, which was originally considered as an antiviral agent, was approved as anti-parkinsonic drug after its wide medical use. The prolonged administration of interferon alpha caused depression in 30-45% of patients, thus limiting its clinical use. The antiviral drug “Oseltamivir” may provoke the development of central side effects, including abnormal behavior, delirium, impaired perception and suicides. Anti-herpethetical drug “Panavir” shows pronounced neuroprotective properties. The purpose of this review is to analyze the experimental and clinical data related to central effects of drugs with antiviral or/and immunotropic activity, and to discover the relationship of these effects with changes in reactivity of immune system and proinflammatory response.
