Full textMicroglia are active sensors of the brain and respond promptly to even minor disturbance in their microenvironment. A feature of this response is the accumulation of these cells at the site of lesion. Neonatal jaundice is a common condition of the newborn and may determine injury to neurons and glial cells, such as microglia, when levels of unconjugated bilirubin (UCB) are excessive. With the objective to evaluate whether microglia have a protective or deleterious role, we decided to assess, using the Boyden chamber, the chemotactic effect of free unbound UCB (fUCB), as well as the migration ability of UCB-treated microglia in the absence or in the presence of chemotatic compounds, such as ATP and S100B. Also, we intended to evaluate the effect of glycoursodeoxycholic acid (GUDCA) as a modulator. To characterize our usual model of microglia isolation, phenotypic evaluation of cultures with different days in vitro (DIV) was performed by estimating cell morphology, nuclear factor-kappaB (NF-κB) activation and phagocytic ability. We observed that fUCB did not act as a chemotactic compound for microglia and that cells treated with UCB showed decreased migration ability. Co-incubation with GUDCA prevented this effect and enhanced microglia migration. However, reduced effects were observed in the presence of ATP and abolished when using S100B. Isolated microglia with 2 DIV showed features of activation, but presentedramified morphology of the “resting” state, less NF-κB activation and increased phagocytosis at 13 DIV. Data indicate that microoglia exposure to UCB leads to a reduced migration ability and that co-incubation with GUDCA prevents this deleterious effect, resulting in an increased migration. Characterization of microglia phenotypes, along the time in culture, point to 13 DIV cells as the most suitable for studies intended to evaluate microglia reactivity to UCB, and probably to other stimuli.

Genetic mapping by association is an unbiased approach to discover genes and pathways influencing disease traits and response to drugs and environmental exposures. There are two key obstacles to mapping in humans: (1) The full sequence of study subjects cannot yet be obtained; and (2) There are substantial limits to the phenotypes that can be safely elicited or measured. Geneticists thus rely on practically measurable sets of genotypes to proxy for the sequence and human in-vitro models that proxy for in-vivo genetics and physiology while allowing for perturbation and characterization in high throughput. This thesis presents the development of one important class of proxy genotypes, those that capture most common genetic variation, as well as an evaluation and refinement of proxy phenotypes offered by one commonly used in-vitro model, the lymphoblastoid cell-line.Capturing common human genetic variation for genome-wide association studies requires genotyping a feasible subset of proxy (or "tag") SNPs. We investigated selection and analysis of tag SNPs, examined the relationship between investment in genotyping and statistical power, and evaluated whether power is compromised when tags are selected from an incomplete resource such as HapMap. We demonstrate an efficient haplotypebased tagging approach and other methods that dramatically increase tagging efficiency. Examining all observed haplotypes for association increases power to detect rare causal alleles, while reducing power for common alleles. Power is robust to completeness of the reference panel and holds across demographically related groups.Lymphoblastoid cell lines (LCLs) are being developed into an in-vitro model where genetics of human gene expression, drug response, and other traits can be studied under controlled conditions. However, the impact of the immortalization process, the relative influence of non-genetic factors, and reproducibility of measured traits are not yet understood.
(cont.) We addressed these questions while mapping loci for response to chemotherapy and found that traits in LCLs are subject to substantial confounders and are only modestly reproducible in independent experiments. Despite this, RNA expression of many genes is affected by genetic variation and predicts response to drugs; integrating SNPs, RNA, and drug response can identify novel pharmacogenetic variation mediated by RNA.

Full textThe study of C. elegans has led to ground-breaking discoveries in gene-function, neuronal circuits, and physiological responses. However, subtle behavioral phenotypes, are often difficult to measure and reproduce across experiments. As part of my dissertation work, I used experimental and computational techniques to quantify and model the dynamics of movement and reproductive behaviors. For movement behaviors, I developed a mathematical approach to correcting the uncertainty of tracking individual animals in a free-moving population, created behavioral profiles for each individual, and used a network to reveal the progression of behavioral changes in the aging process. For reproductive behaviors, I used perturbations in temperature to dissect the key processes that modify the dynamics of the C. elegans reproductive system. The primary goal of creating this set of tools and approaches was to acquire high-quality data for mathematically modeling how individuals respond to environmental stress and modify their behaviors during ageing.

Resumo: Um grande número de estudos em biologia, incluindo os que envolvem a reconstrução de árvores filogenéticas, resultam na produção de uma enorme quantidade de dados -- por exemplo, descrições fenotípicas , matrizes de dados morfológicos , árvores filogenéticas, etc. Biólogos enfrentam cada vez mais o desafio e a oportunidade de efetivamente descobrir conhecimento a partir do cruzamento e comparação de vários conjuntos de dados, nem sempre conectados e integrados. Neste trabalho, estamos interessados em um contexto específico da biologia em que biólogos aplicam ferramentas computacionais para construir e compartilhar descrições digitais dos seres vivos. Nós propomos um processo que parte de fontes de dados fragmentadas, que nós mapeamos para grafos, em direção a uma plena integração das descrições através de ontologias. Os bancos de dados de grafos intermediam o processo de evolução. Eles são menos dependentes de esquema e, uma vez que ontologias também são grafos, o processo de mapeamento do grafo inicial para uma ontologia torna-se uma sequência de transformações no grafo. Nossa motivação parte da ideia de que a conversão de descrições fenotípicas em uma rede de relações e a busca de conexões entre elementos relacionados irá aumentar a capacidade de resolver problemas mais complexos suportados por computadores. Este trabalho detalha os princípios de concepção por trás do nosso processo e duas implementações práticas como prova de conceito
Abstract: A large number of studies in biology, including those involving phylogenetic trees reconstruction, result in the production of a huge amount of data -- e.g., phenotype descriptions, morphological data matrices, phylogenetic trees, etc. Biologists increasingly face a challenge and opportunity of effectively discovering useful knowledge crossing and comparing several pieces of information, not always linked and integrated. In this work, we are interested in a specific biology context, in which biologists apply computational tools to build and share digital descriptions of living beings. We propose a process that departs from fragmentary data sources, which we map to graphs, towards a full integration of descriptions through ontologies. Graph databases mediate this evolvement process. They are less schema dependent and, since an ontology is also a graph, the mapping process from the initial graph towards an ontology becomes a sequence of graph transformations. Our motivation stems from the idea that transforming phenotypical descriptions in a network of relationships and looking for links among related elements will enhance the ability of solving more complex problems supported by machines. This work details the design principles behind our process and two practical implementations as proof of concept

Full textAsthma in childhood seems affected by exposure to various factors in early life. To assess this hypothesis, we conducted 2 studies: one in France, and the other in Lebanon. In the French study, we aimed at describing wheezing phenotypes between the ages of two months and one year, and assess risk factors associated with these wheezing phenotypes in a large birth cohort. In the Lebanese study, the aims were to evaluate the associations between caregiver-reported use of medications, alcohol, cigarette and/or waterpipe (WP), and exposure to pesticides/detergents during pregnancy with childhood-onset asthma in Lebanon and to validate the Arabic version of the Asthma Control Test (ACT) among these children and identify risk factors that might affect asthma control.Methods: We studied 18,041 infants from the ELFE (French Longitudinal Study of Children) birth cohort. Parents reported wheezing and respiratory symptoms at two and 12 months, and answered a complete questionnaire (exposure during pregnancy, parental allergy).The study design of the Lebanese project consisted of a case-control study, conducted between December 2015 and April 2016, recruited 1503 children, aged between 3-16 years old. A questionnaire assessed the sociodemographic characteristics (age, gender, education level of both parents), the family history of asthma, and other known risk factors of asthma (heating system at home, child history of recurrent otitis, humidity in the house, child went to a daycare, smoking and drinking alcohol during pregnancy, exposure to pesticides and detergents).Results: Children with no symptoms (controls) accounted for 77.2%, 2.1% had had wheezing at two months but no wheezing at one year (intermittent wheezing), 2.4% had persistent wheezing, while 18.3% had incident wheezing at one year. Comparing persistent wheezing to controls showed that having one sibling (ORa=2.19) or 2 siblings (ORa=2.23) compared to none, nocturnal cough (OR=5.2), respiratory distress (OR=4.1) and excess bronchial secretions (OR=3.47) at two months, reflux in the child at 2 months (OR=1.55), maternal history of asthma (OR=1.46) and maternal smoking during pregnancy (OR=1.57) were significantly associated with persistent wheezing. These same factors, along with cutaneous rash in the child at 2 months (OR=1.13) and paternal history of asthma (OR=1.32) were significantly associated with increased odds of incident wheezing. Having one sibling (ORa=1.9) compared to none, nocturnal cough at 2 months (OR=1.76) and excess bronchial secretions at 2 months (OR=1.65) were significantly associated with persistent compared to intermittent wheezing.In the Lebanese study, the multivariate analysis showed that children living in North and South Lebanon and the children living in areas where pesticides are frequently used had an increased risk of asthma (ORa=1.625; ORa=13.65; ORa=3.307) respectively. Smoking WP during pregnancy and cigarette during lactation would increase the risk of asthma in children (ORa=6.11; ORa=3.44 respectively). A high Cronbach’s alpha was found for the full scale (0.959). As for the asthma control scale (ACT), the correlation factors between each item of the ACT scale and the whole scale ranged between 0.710 and 0.775 (p<0.001 for all items). Mother’s low educational level as well as the history of asthma in the mother and the father would significantly increase the risk of uncontrolled asthma (Beta= 1.862; Beta= 3.534; and Beta= 1.885 respectively). Cigarette smoking during breastfeeding and waterpipe smoking by the mother during pregnancy were both significantly associated with uncontrolled asthma (Beta= 2.105; Beta=2.325 respectively). Mother’s high educational level was significantly associated with more asthma control (Beta= -0.715)

Full textENGLISH ABSTRACT: The latest strategies in the protection of crops against microbial pathogens are rooted in harnessing the natural, highly complex defense mechanisms of plants through genetic engineering to ultimately reduce the application of chemical pesticides. This approach relies on an in-depth understanding of plant-pathogen interactions to develop reasonable strategies for plant improvement. Among the highly specialized defense mechanisms in the plant’s arsenal against pathogen attack, is the de novo production of proteinaceous antimicrobial peptides (AMPs) as part of the plant’s innate immunity. These AMPs are small, cysteine-rich peptides such as plant defensins that are known for their broad-spectrum of antifungal activity. These plant defensin peptides have been found to be present in most, if not all plant species and the defensin encoding genes are over-represented in plant genomes. Most of these defensins are generally the products of single genes, allowing the plant to deliver these molecules relatively rapidly and with minimal energetic expense to the plant. These factors contribute to establishing AMPs as excellent candidates for genetic engineering strategies in the pursuit of alternative crop protection mechanisms. The first antimicrobial peptide identified and isolated from grapevine, Vv-AMP1, was found to be developmentally regulated and exclusively expressed in berries from the onset of ripening. Recombinantly produced Vv-AMP1 showed strong antifungal activity against a wide range of plant pathogenic fungi at remarkably low peptide concentrations in vitro, however, no in planta defense phenotype could thus far be linked to this peptide. In this study, the antifungal activity of Vv-AMP1 constitutively overexpressed in its native host (Vitis vinifera) was evaluated against grapevine-specific necrotrophic and biotrophic fungi. Firstly, a hardened-off genetically characterised transgenic V. vinifera (cv. Sultana) population overexpressing Vv-AMP1 was generated and morphologically characterized. In order to evaluate the in planta functionality of Vv-AMP1 overexpressed in grapevine, this confirmed transgenic population was subjected to antifungal assays with the necrotrophic fungus, B. cinerea and the biotrophic powdery mildew fungus, Erysiphe necator. For the purpose of infection assays with a biotrophic fungus, a method for the cultivation and infection with E. necator was optimized to generate a reproducible pathosystem for this fungus on grapevine. Detached leaf assays according to the optimized method with E. necator revealed programmed cell death (PCD) associated resistance linked to overexpression of Vv-AMP1 that can be compared to that of the highly resistant grapevine species, Muscadinia rotundifolia. Contrastingly, whole-plant infection assays with B. cinerea revealed that Vv-AMP1 overexpression does not confer V. vinifera with elevated resistance against this necrotrophic fungus. An in silico analysis of the transcription of defensin-like (DEFL) genes previously identified in grapevine was included in this study. This analysis revealed putative co-expression of these DEFL genes and other genes in the grapevine genome driven by either tissue- or cultivar specific regulation or the plant’s response to biotic and abiotic stress stimuli. In conclusion, this study contributed to our knowledge regarding Vv-AMP1 and revealed an in planta defense phenotype for this defensin in grapevine. In silico analysis of the DEFL genes in grapevine further revealed conditions driving expression of these genes allowing for inferences to be made regarding the possible biological functions of DEFL peptides in grapevine.
AFRIKAANSE OPSOMMING: Die nuutste strategieë wat deel vorm van die beskerming van plant gewasse teen mikrobiese patogene het hul oorsprong in die inspanning van die natuurlike, hoogs gekompliseerde verdedigingsmeganismes van die plant deur middel van genetiese enginieurswese ten einde die gebruik van chemiese plaagdoders te verlaag. Hierdie benadering maak staat op ‘n in-diepte begrip van plant-patogeen interaksies om verstandige strategieë vir plantverbetering te kan ontwikkel. Van hierdie hoogs-gespesialiseerde verdedigingsmeganismses in die plant se arsenaal teen patogeen aanvalle sluit die de novo produksie van proteinagtige antimikrobiese peptiede (AMPs) in as deel van die plant se ingebore immuunstelsel. Hierdie AMPs is klein, sisteïen-ryke peptiede soos die plant “defensins” en is bekend vir hul breë-spektrum antifungiese aktiwiteit. Hierdie plant defensinpeptiede word aangetref in meeste, indien nie alle plant spesies nie en die defensin koderende gene word oor-verteenwoordig in plant genome. Meeste van hierdie defensins is gewoonlik die produkte van enkele gene wat die plant in staat stel om hierdie molekules relatief spoedig en met minimale energie verbruik in die plant te vorm. Hierdie faktore dra by tot die vestiging van AMPs as uitstekende kandidate vir genetiese ingenieursstrategieë as deel van die strewe na alternatiewe gewasbeskermingsmeganismes. Die eerste antimikrobiese peptied wat geïdentifiseer en geïsoleer is uit wingerd, Vv-AMP1, word beheer deur die ontwikkelingsstadium en word eksklusief uitgedruk in korrels vanaf die aanvang van rypwording. Rekombinant-geproduseerde Vv-AMP1 het sterk antifungiese aktiwiteit getoon teen ‘n wye reeks plantpatogeniese swamme teen merkwaardige lae peptied konsentrasies in vitro, alhoewel geen in planta verdedigingsfenotipe tot dusver gekoppel kon word aan hierdie peptied nie. In hierdie studie was die antifungiese aktiwiteit van Vv-AMP1 wat ooruitgedruk is in sy natuurlike gasheerplant (Vitis vinifera) ge-evalueer teen wingerd-spesifieke nekrotrofiese- en biotrofiese swamme. Eerstens is ‘n afgeharde geneties-gekarakteriseerde transgeniese V. vinifera (cv. Sultana) populasie wat Vv-AMP1 ooruitdruk gegenereer en morfologies gekarakteriseer. Om die in planta funksionaliteit van Vv-AMP1 ooruitgedruk in wingerd te evalueer is hierdie bevestigde transgeniese populasie blootgestel aan antifungiese toetse met die nekrotrofiese swam, B. cinerea en die biotrofiese swam, Erysiphe necator. Vir die doel om infeksiestudies uit te voer met ‘n biotrofiese swam is ‘n metode geoptimiseer vir die kweek en infeksies met E. necator wat gelei het tot ‘n herhaalbare patosisteem vir hierdie swam op wingerd. Blaarstudies, volgens die pas-verbeterde metode vir E. necator infeksies het ‘n geprogrammeerde seldood-geassosieërde weerstand, gekoppel aan die ooruitdrukking van Vv-AMP1 onthul, wat vergelyk kan word met dié van die hoogs-weerstandige wingerdspesie, Muscadinia rotundifolia. Hierteenoor het heel-plant infeksie studies met B. cinerea onthul dat Vv-AMP1 ooruitdrukking geen verhoogde weerstand teen dié nekrotrofiese swam aan V. vinifera bied nie. ‘n In silico analise van die transkripsie van defensin-agtige (DEFL) gene wat vroeër in wingerd geïdentifiseer is, is by hierdie studie ingesluit. Hierdie analise het vermeende gesamentlike uitdrukking van hierdie DEFL gene en ander gene in die wingerd genoom onthul wat aangedryf word deur weefsel- of kultivar-spesifieke regulering of die plant se reaksie tot biotiese en abiotiese stress stimuli. Ten slotte, hierdie resultate het bygedra tot ons kennis in verband met Vv-AMP1 en het ‘n in planta verdedigingsfenotipe vir hierdie defensin in wingerd onthul. In silico analiese van die DEFL gene in wingerd het verder toestande onthul wat die uitdrukking van hierdie gene aandryf wat ons toelaat om aannames te maak ten opsigte van die moontlike biologiese funksies van DEFL peptiede in wingerd en ondersteun die opstel en toets van hipoteses vir die rol en megansimes van aksie van die wingerd defensin familie.

Full textPopulations are faced with selective pressures that act on certain traits resulting in phenotypic divergence. The evolution of adaptive morphological traits is often associated with changes in pre-Existing structures. In semiaquatic insects, a dramatic growth of thoracic appendages is associated with their adaptation and efficient locomotion on the water surface. This particular leg allometry facilitated the exploitation of aquatic habitats, a restricted niche for their terrestrial relatives; and hence opens a new array of ecological opportunities. Additionally, the derived group of water striders has undergone further appendage modification, such that T2-Legs are longer than T3-Legs, a ground plan associated with the specialization to open water. Water striders have evolved a derived mode of locomotion through rowing on water. They move their mid-Legs in simultaneous sweeping strokes for propulsion, and move their hind-Legs in fine movements for orientation. Leg specification and elongation in semiaquatic insects happens during early embryogenesis as the newly hatching nymphs emerge with functional legs. The Hox transcription factor Ubx was found to be implicated in the reversal in leg ground plan. Nonetheless, the genetic mechanisms underlying these leg adaptive changes are still poorly understood. The presented thesis investigates these questions through two main goals: first, to uncover the genes and pathways implicated in the development and dramatic elongation of the legs; second, to examine the dynamics of Hox control responsible for the reversal in leg ground plan characteristic of water striders
