Abstract:

Endometriosis (EM) and Leiomyoma (UL) are two most frequent benign tumors of monoclonal origin affecting about 30% of all women in their reproductive age. Though known for centuries many aspects of pathogenesis and pathophysiology of EM and UL remain unknown so far. Modern molecular technologies have made tremendous impact in our understanding of both disorders. The report gives comparative analysis of molecular mechanisms of EM and UL including recent data on their origin, progression and peculiarities of manifestation. Similarities and differences of molecular mechanisms underlying their early stages are enlighten from position of systems genetics with particular emphasis on genetic specificity, gene interactions and epigenetic mechanisms regulating normal and pathologic development. Comparison of epigenetic landscapes of EM andUL progression underlying peculiarities and unique personal clinical manifestations are outlined. The origin of both tumors
as outgrowths of the relevant stem cells with mesenchymal commitment lineage migrating from endometrium/myometrium junctional zone of the uterus is hypothesized. Differences in mechanisms of stem cell origin and tumor progression resulting from epigenetic landscape peculiarities as basic reason of many clinical forms as well as unique individual manifestation of EM and UL are suggested Proofs advocating for syntropy of molecular mechanisms underlying both disorders are presented. Perspectives of the further studies of EM and UL from the platform of systems genetic with assistance of new molecular technologies and bioinformatic analysis are briefly discussed.

Abstract:

Until recently, colorectal cancer (CRC) has been viewed as relatively homogeneous disease despite recognition of various histological types of this disease. Over the last 25 years it has become clear that CRC evolves through multiple molecular pathways which have different precursors. About 30% of all CRCs develop through a serrated pathway in reference to crypt morphology in their precursor polyps termed sessile serrated adenomas/polyps (SSA/P). Distinguishing between early SSA/P and other colorectal polyps including innocuous hyperplastic polyps (HPs) is challenging and may not be possible in routine practice. We performed gene expression profiling (GEP) of serrated colorectal polyps and conventional adenomas and shown a significantly (p<0.05) higher expression of Cathepsin E in sessile serrated adenomas as compared to hyperplastic polyp and tubular adenomas. Trefoil Factor 1 showed the same trend of expression for sessile serrated adenomas as compared to
hyperplastic polyps and was significantly higher in both polyps compared to tubular adenomas. More recently, our study conducted between hyperplastic polyps and SSA/P using GEP with qRT-PCR and immunohistochemistry validation identified Claudin 1 (CLDN1) as the most statistically significant differentially expressed gene in BRAF V600E mutant polyps regardless of histological subtype of serrated polyp type (p<0.0005). Our results demonstrated an apparent heterogeneity on the molecular level within the HPs group and suggest that HPs with somatic BRAF V600E mutation and up-regulated expression of CLDN1 are closely related to SSA/P and may in fact represent a continuous spectrum of the same neoplastic process within the serrated pathway of colorectal carcinogenesis.

He has had a career long interest in genetic deafness and has made many significant contributions. He is the author of more than 200 scientific papers in top journals. His exemplary translational research on hereditary hearing loss from basic sciences to clinical application (bench to bedside) for the past three years, ranking in the top 1 percent of NIH-funded physician-scientists in the auditory field.

Abstract:

We have established the Miami Ontogenetic Program combining the research and the clinical component. The program has provided a unique platform to carry out translational research on delivering genetic services to deafness patient care. The extreme heterogeneity of non-syndromic sensorineural hearing loss (NSHL) makes serial sequencing approaches unfavorable in terms of efficiency and cost. However, the discovery that genes at only 2-3 loci account for a major component of human deafness suggested that the sequential screening of DNA samples from probands in multiplex sibships for mutations would be a cost effective strategy. We aim to identify the genetic cause of NSHL through an integrated paradigm combining microarray, copy number variations (CNVs) analysis, whole genome sequencing (WES) and a hearing-centric database. We are using a DNA microarray panel (Miami-CapitalBio) as the initial screening to simultaneously detect the most common deafness-causative mutations from four genes. We then perform a custom capture/next-generation sequencing gene panel (MiamiOtoGenes) composed of 180 known deafness genes (Agilent SureSelect DNA Design). Patients for whom the two panels do not provide a meaningful result, WES is performed to achieve a comprehensive interrogation of the full spectrum of variants to detect single-nucleotide variants (SNVs), insertion/deletions (Indels) and CNVs. If variants are not found in the genes included on Miami-CapitalBio and MiamiOtoGenes, WES should be considered in small multiplex families. The multidisciplinary team approach is an effective way to bring the sequencing data to clinical practice for the clinical diagnosis and management of deaf and hard-of-hearing families.

Abstract:

Next Generation Sequencing revealed an intricate distribution of millions of genetic variants among different human populations. Both rare and frequent genetic variants may bring to light important information about history, evolution and health status of humans. First, we present a novel computational method for detecting identical-by-descent (IBD) chromosomal segments between sequenced genomes. It utilizes the distribution patterns of very rare genetic variants (vrGVs), which have minor allele frequencies less than 0.2%. Contrary to the existing probabilistic approaches our method is rather deterministic, because it considers a group of very rare events which cannot happen together only by chance. This method has been applied for exhaustive computational search of shared IBD segments among 1092 sequenced individuals from 14 populations. It demonstrated that clusters of vrGVs are unique and powerful markers of genetic relatedness, that uncover IBD chromosomal segments between and within populations, irrespective of whether divergence was recent or occurred hundreds-to-thousands of years ago. We found that several IBD segments are shared by practically any possible pair of individuals belonging to the same population. Moreover, shared short IBD segments (median size 183 Kb) were found in 10% of inter-continental human pairs, each comprising of a person from Sub-Saharan Africa and a person from Southern Europe. The shortest shared IBD segments (median size 54 Kb) were found in 0.42% of inter-continental pairs composed of individuals from Chinese/Japanese populations and Africans from Kenya and Nigeria. Knowledge of inheritance of IBD segments is important in clinical case-control and cohort studies, since unknown distant familial relationships could compromise interpretation of collected data. Clusters of vrGVs should be useful markers for familial relationship and common multifactorial disorders. Lastly, we present whole-genome investigation of human most frequent genetic variants and their arrangement in common haplotypes in various geographical regions. Three prominent types of common haplotypes “Yin”, Yang” and “Mosaic” are described as well as their continent distribution. They represent three principal ancient lineages of mankind.

Abstract:

Type-2 diabetes (T2D) and obesity are complex disorders that constitute major public health problems. The evidence for familial aggregation of both T2D and obesity is substantial. To date, more than 150 genetic loci are associated with the development of monogenic, syndromic or multifactorial forms of T2D or obesity; many within lipid and carbohydrate metabolism pathways. SNPs located in or near FTO, MC4R, MC3R, POMC, LEP, LEPR, PLIN1, APOA5, LIPC, FABP2, INSIG2, IRS1, GIPR, ADBR2, ADRB3, UCP1, RETN, ADIPOQ, IL6, PPARG, TCF7L2 and CLOCK, among others, are implicated in both diabetes and obesity gene networks, pleomorphic with nutritional and metabolic traits. A personalized nutritional approach, based not only on phenotypic traits but also on genetic make-up, may help to control body weight and obesity. Recent advances in nutrigenetics, bioinformatics and genome-wide association metabolomics studies are set to unleash a revolution in personalized nutrition. In this symposium, we discuss the evidence concerning the genetic contribution to individual risk of T2D and obesity and explore the potential role of nutritional and environmental mechanisms. We also explain how genetics, epigenetics and environment are likely to interact to define the individual risk of disease; through analyzing the results of a number of recent human clinical trial studies that use genetics to personalize treatment plans for obesity, metabolic syndrome and diabetes management. The aim of these studies was to determine the impact of a targeted, precision treatment program on reducing a patient’s future risk of metabolic syndrome (MetS).

Abstract:

Understanding the molecular genetics of hereditary eye disorders is essential not only for early diagnosis but also to arrest the progression of the disease. North Indian population encompassing Eastern Uttar Pradesh and Western Bihar has been untouched in terms of understanding the genetics of eye disorders. We have recruited several families afflicted with various ocular diseases like X-linked idiopathic congenital nystagmus (XLICN), X-linked retinoschisis (XLR), macular dystrophy etc. We have identified a novel missense mutation c.556A>G (p.M186V) in the FRMD7. A recurrent missense mutation c.242T>A (p.I81N) in the gene Retinoschisin (RS1) was also identified in XLR. The c.242T>A mutation leads to an Ile81Asn substitution in the Discoidin domain of the RS1protein which is likely to interfere with the function of the RS1 protein. Detailed in silico analysis also supports the pathogenecity of these variants. We have also carried out WES (whole exome sequencing) in families with macular dystrophy and identified causal mutations. Collectively, this study will help us in identification of rare and novel genetic variants in our population that could be used as diagnostic genetic markers. This will also improve our understanding towards molecular mechanism and genetic basis of various eye disorders. Variants identified in this manner will enable us predict the predisposition towards a genetic ocular disorder and will facilitate early diagnosis and better management of such diseases.

Abstract:

Our recent extensive research of the Roma (Gypsy) population in Croatia pointed to a significant load of risk factors for the different diseases which accompany economic transition, indicating a rising prevalence of cardiovascular diseases (CVD) in the future. This may lead to the increase of appropriate drugs consumption in this population. The active transport of numerous medications for CVD treatment is mediated by OATP1B1 protein encoded by SLCO1B1 gene. This gene has numerous variants which can cause adverse drug response and some of them significantly differentiate among populations. The Roma are transnational minority whose gene pool results from their Indian ancestry, subsequent admixture with surrounding populations and their socio-cultural isolation. Their reactions to different drugs are poorly documented. Therefore we analyzed 8 SNP loci within SLCO1B1 gene in 434 Roma individuals from three socio-culturally different Roma groups (Balkan Roma, Vlax Roma from Baranja and Medjimurje). All but one locus, rs4149056, were monomorphic. The polymorphic locus shows significantly different genotype distributions among the investigated populations (p<0.01). Genotype CC, responsible for the adverse response to several drugs, was present only in the population of Baranja, where frequency of C allele was the highest (16.8%). Comparison of allele frequencies of here investigated Roma populations with major population groups from 1000 genomes database did not reveal any significant difference compared to European populations but indicated difference between the Roma and South Asian populations. The results, obtained for rs4149056, indicate that the investigated Roma population shows sub-population specificity within the bounds of European populations.

Abstract:

From rare and unusual conformations such as stem, loop, stem-and-loop and rigid rod of native plant mitochondrial DNA (mtDNA) and reproduction of such structures with space-filling model of DNA a concept of foldback intercoil (FBI) DNA was developed. Foldback bending at one point of an unwound parallel duplex DNA can lead the flanking antiparallel double helix B-DNA intertwine in each other’s major groove to form an intercoil. When a repeat sequence encounters its partner in the intercoil four-stranded base pairing can form and lead to heteroduplexes formation by base flipping. As tested by the space filling model based upon experimental documents in the literature, FBI DNA is shown to perform DNA-DNA transactions of short (about 7 bp) repeats; namely, α-deletion by direct repeats, Ω site-specific inversion by inverted repeats, FBI tip insertion in site-specific insertion and non-homologous end joining and gap filling (EHEJ-GF) in transposition. Rigid rod DNA can be interpreted in the context of the FBI DNA as reflection of cellular processes such as DNA replication and transcription, enhancer function and heteroduplexes formation by long repeats. DNA rearrangement in the genome is known to be one of the major causes of human genetic disorders and diseases. Massive accumulation of genome sequence data and comparative genomics reveal at the breakpoints not a single nucleotide but about 7 bp block of an overlapping breakpoint, which manifests the FBI DNA mechanism at work. Concerted presentations of such supporting evidences in the “World Congress of Human Genetics” would mark an epoch of “Genomic Revolution”.

Abstract:

In a High Medieval age cemetery, dated from the XIII-XIV century (Uceda, Guadalajara, Central Spain), two bodies were found, buried in a curious position. One of the bodies, an adult, had close to its abdominal area a small number of little bones. It was not clear if it could have been a pregnant woman or, otherwise, two separated burials, at different times. Anthropological experts confirmed that the second individual should be a fetus, being absolutely impossible to determine the sex. Furthermore, the adult was appointed as a woman. Concerning the condition of the samples, the adult one was preserved, obeying to the authenticity criteria to select evidences for a critical DNA analysis. But the samples belonging to the second individual were very delicate and fragile, complicating the sampling work. A genetic study will be carried out to find if there is any biological bond between the individuals, as well as, their biological sex. The analysis procedure had to be somewhat modified due to the sensitivity of the second individual samples. So far, our preliminary results reveal that, if both individuals are not linked by maternal kinship, they must be, at least, relatives by maternal side, since they share the same maternal lineage. Conclusions reached in the present study can help in mass disasters cases. In such situations, it is crucial to determine kinships between samples, despite their advanced state of degradation, which makes the improvement of this procedure a crucial point in forensic genetics.

Abstract:

Aim: To demonstrate that pregnancy complications are associated with alterations in cardiovascular and cerebrovascular microRNA expression in maternal circulation. We focused on microRNAs playing a role in pathogenesis of dyslipidemia, hypertension, vascular inflammation, insulin resistance and diabetes, atherosclerosis, angiogenesis, coronary artery disease, myocardial infarction and heart failure.

Methods: Gene expression of 29 microRNAs was compared between groups (39 GH, 68 PE, 33 IUGR and 20 normal pregnancies) and correlated with the severity of the disease with respect to clinical signs, delivery date and Doppler US parameters.

Results: The down-regulation of miR-100-5p, miR-125b-5p and miR-199a-5p was a common phenomenon shared between GH, PE and IUGR. IUGR induced down-regulation of miR-17-5p, miR-146a-5p, miR-221-3p and miR-574-3p. Irrespective of the severity of the disease, PE was associated with the dysregulation of miR-100-5p and miR-125b-5p and IUGR with dysregulation of miR-199a-5p. PE terminated before 34 weeks was associated with down-regulation of miR-146a-5p, miR- 199a-5p and miR-221-3p. Weak negative correlation between miR-146a-5p and miR-221-3p expression and the PI in umbilical artery was found. Additional microRNAs (miR-103a-3p, miR-126-3p, miR-195-5p and miR-499a-5p) showed a trend to down-regulation.

Conclusion: MicroRNAs playing a role in pathogenesis of dyslipidemia (miR-146a-5p), vascular inflammation (miR-126- 3p, miR-146a-5p, miR-195-5p, miR-221-3p), insulin resistance and diabetes (miR-126-3p), atherosclerosis (miR-126-3p), angiogenesis (miR-17-5p, miR-100-5p, miR-221-3p), coronary artery disease (miR-17-5p, miR-126-3p, miR-195-5p, miR- 221-3p), myocardial infarction and heart failure (miR-17-5p, miR-100-5p, miR-103-3p, miR-125b-5p, miR-195-5p, miR-199a- 5p, miR-499a-5p, miR-574-3p) were also dysregulated in maternal whole peripheral blood during the onset of pregnancy complications such as gestational hypertension, preeclampsia or IUGR.

Abstract:

Several studies have shown that testis-specific gene antigen (TSGA10) could be considered as a cancer testis antigen (CTA), except for one study which has identified it as a tumor suppressor gene. In order to exert its function, TSGA10 interacts closely with hypoxia inducible factor (HIF-1α) and since this interaction is still not completely defined, the exact role of TSGA10 in angiogenesis and invasion is also under question. The current study was conducted to investigate the function of TSGA10 gene and evaluate its potential effects on tumor angiogenesis and invasion. To do so, TSGA10 vector was designed for a stable transfection in HeLa cells and then clonal selection was applied. The efficiency of transfection and the role of TSGA10 in above mentioned targets were evaluated by real-time PCR, western blot, zymography and ELISA tests in both normoxia and hypoxia. Invasion, migration and angiogenesis were assessed. Three-dimensional model of TSGA10 protein was accurately built in which TSGA10 docked to 2 domains of HIF-1α. Increased expression of TSGA10 correlated with decreased HIF-1α transcriptional activity and inhibited angiogenesis and HeLa cells invasion in normoxia as well as hypoxia. Docking analysis indicated that binding affinity of TSGA10 with TAD-C (CBP) domain of HIF-1α would be stronger than that with PAS-B domain. Our findings showed that overexpression of TSGA10 would induce disruption of HIF-1α axis and exert potent inhibitory effects on tumor angiogenesis and metastasis. Therefore, TSGA10 could be considered as a potent therapeutic candidate, prognostic factor and a cancer management tool.

Abstract:

Background & Aim: It has been postulated that conventional suture materials such as silk may enhance bacterial biofilm growth causing delay in healing of surgical sites. Nano-silver particles with their anti-bacterial agent properties could be helpful. This study evaluates the role of nano-silver particles on the inflammatory process of gingival suture in comparison with usual silk suture in animal model.

Method & Materials: In this double-blind clinical random study, 12 female rabbits were selected. They had healthy teeth and no periodontal disease had been found by clinical and radiographic examinations. Our innovated nano-silk was prepared in sterile condition and under special circumstances with nano-silver particles. Two different density of Nano-silk (A and B) were prepared. A suture contained 60 ng of silver and B sutures included 120 ng of silver. Nano-silk sutures thread and conventional silk suture thread were sutured on the buccal surface of the gingiva of mandibular incisors. Histological changes on 4th and 7th day after suturing were evaluated to assess the inflammatory process.

Results: The histological results showed that the application of this new suture material may improve inflammation process and promote wound healing. We also observed a relatively marked difference between the two groups in the 4th and 7th day in the inflammatory cell components and edema. These two parameters are important factors in the wound inflammation process. Our results suggested that the density of nano-silver particles in nano-silk B causes less inflammatory response in comparison with nano-silk A and therefore a better scaffold for parenchymal and mesenchymal factors is made one week after surgery.

Conclusion: Silver particles due to their beneficial effects as antibacterial and wound healing accelerator in the periodontal surgeries could reduce inflammation and promote healing process. So nano-silver sutures could be helpful for and produce a more favorable healing when used in oral and maxillofacial surgery.

Abstract:

Dual-specificity tyrosine phosphorylation-regulated kinase 1A (DYRK1A) is a strong therapeutic target to ameliorate cognitive functions of Down Syndrome (DS). Genetic normalization of DYRK1A is sufficient to normalize early cortical developmental phenotypes in DS mouse models. Gyrencephalic human neocortical development is more complex than that in lissencephalic mice, hence cerebral organoids (COs) can be used to model early neurodevelopmental defects of DS. Single copy DYRK1A knockout COs (scDYRK1AKO-COs) can be generated from manipulated DS derived (DS-) induced pluripotent stem cells (iPSCs) and genetic normalization of DYRK1A is expected to result in corrected neurodevelopmental phenotypes that can be reminiscent of normal COs. DYRK1A knock-in (DYRK1AKI) COs can be derived after genetic manipulations of normal iPSCs and would be valuable to evaluate impaired neocortical development as can be seen in DS-COs. DYRK1A mutations cause severe human primary microcephaly, hence dose optimization studies of DYRK1A inhibitors will be critical for prenatal therapeutic applications in DS. Several doses of DYRK1A inhibitors can be tested in the neurodevelopment process of DS-COs and DS-scDYRK1AKO-COs would be used as optimum models for evaluating phenotypic ameliorations. Overdose drug exposure in DS-COs can be explained by similar defects present in DS-baDYRK1AKO-COs and DYRK1AKO-COs. There are several limitations in the current CO technology, which can be reduced by the generation of vascularized brain-like organoids giving opportunities to mimic late-stage corticogenesis and complete hippocampal development. In the future, improved DS-DYRK1AKO-COs can be efficient in studies that aim to generate efficiently transplantable and implantable neurons for tissue regeneration alternatives in DS individuals.

Abstract:

Data from the WHO shows that in 2014, there are around 9.6 million people in the world diagnosed with tuberculosis (TB). Almost 95% of those TB related deaths occur in developing countries (WHO, 2015). TB remains an important health challenge and a significant economic burden for Kazakhstan and in Central Asia. The bacteria Mycobacterium tuberculosis is uniquely adapted to evade the host immune system to eventually establish infection in the host. Recent findings show a number of immunological related processes such as macrophage activation and recruitment and host M. tuberculosis defense are impacted by a variety of genes of the human host. These genes include those that play a role in host immune factors, those that regulate oxidative immune response, inflammatory response and vitamin D metabolism. These genes have been found to contribute to the susceptibility of the host to persistent TB infection. We are interested in the genetic variation of genes affecting immunological responses towards tuberculosis infection and their association with infection in different ethnic groups in Kazakhstan and Central Asia. We have genotyped 60 Kazakhs with and without TB, specifically looking at 10 SNPs belonging to the following genes DHCR7, CYP2R1, GC-1, CYP24A1, CYP27A1, CYP27B1, and the VDR. These genes are involved in the pathways of vitamin D metabolism playing a number of different roles including synthesis, activation, delivery and binding of the activated vitamin. Our preliminary results indicate association of these SNPs with TB susceptibility and we are presently developing strategies for a genetic based supplement intervention.

Abstract:

Speed is limited morphologically and physiologically by different factors. Among others, human dimensions and osteomuscular ratios determine speed performance at biomechanical level. The number and type of contractile fibers, favoring anaerobic or aerobic energy supply, provide another restriction for muscle power. Even all of them could be modified under certain conditions in a limited rate through exercise training; there are always restrictions by ethnic variations due to genetic heritage of such populations. Finally, molecular storage capacity and kinetic for each pathway is at first line restraining real performance instead of any other improvement at other levels. Records from race constitute a first approach for integrated and non-integrated metabolic system for power supply at muscle fibers. Without drugs influence, they represent the best net effort from the muscular and metabolic machinery of those individuals for different distances. A mathematical modeling was developed for ranges analysis for best performance at different energetic supply rates for establishing tendencies and limits in power. Equations during heterochronism phase reveal speed increase of up to a=4.66 m/s2 (R²=0.9866) until reach a maximum speed of 11.79 m/s for few seconds and a global equation for overall performance of V=-0.646 ln(t)+11.097 (R²=0.9104). Equations by intervals are provided with statistical analysis for each determination with the metabolic interpretation and biological relevance, giving benefits for health during recovering process and evaluation derived from both physical training and fitness and a potential tool for evaluating individual’s capacities and discovering of disruptions.
