Full textThe Inuit population of Nunavik is exposed to persistent organic pollutants (POPs) through its traditional diet. Some POPs (i.e. hydroxylated metabolites of polychlorinated biphenyls, pentachlorophenol and perfluorooctane sulfonate) compete with thyroxin (T4) for binding sites on transthyretin (TTR), a transport protein of thyroid hormones. We tested the hypothesis that POPs decrease circulating concentrations of T4 bound to TTR (T4-TTR) in Inuit women of reproductive age, who were previously enrolled in the 2004 Inuit health study Qanuippitaa? How are we?. We measured the concentration of T4-TTR in plasma samples obtained from 120 Inuit women (18-39 years old). Linear regression analyses revealed that TTR, TBG and total T4 concentrations were significant predictors (p < 0.002) of T4-TTR levels but not POPs levels (model adjusted R-square = 0.27, p < 0.0001). Our results suggest that circulating levels of POPs in these women are not high enough to affect TTR-mediated thyroid hormone transport.

Full textAfter the selection of different sets of proteins with a pharmacological interest (sc-PDB databank) and the identification of their binding sites, these sets have been used to validate and to do screenings with a structural alignment program, SiteAlign. SiteAlign use a discretized sphere and normalized scores to compare two binding sites. A scoring protocol, then the possible applications of the program have been determined. SiteAlign can be used for functional annotations of genomic proteins, for predictions of cross reactivity and predictions of ligands targets (experimental validation of this calculation). SiteAlign has then been used, in the chemogenomic part of the project, for studying in 3D the G-coupled protein receptors and for suggesting new ligands for orphan receptors. Last, SiteAlign has been used to compare the structural space of sc-PDB sites

Full textCette thèse de doctorat porte sur le transport du silicium (Si) par les aquaporines animales. Le Si est un élément abondant dans la nature où il joue des rôles im-portants, chez les plantes notamment. Il jouerait également des rôles importants en physiologie animale en contribuant à l’intégrité osseuse, à la santé tégumen-taire et au maintien du collagène. Bien que des transporteurs de Si soient déjà connus chez les diatomées et les plantes, aucun n’a encore été décrit chez l’animal. Toutefois, la compartimentalisation du Si au sein de l’organisme et son assimilation nutritionnelle suppose l’existence de tels transporteurs. En raison de l’homologie qu’elles partagent avec les transporteurs de Si chez les plantes, les aquaporines (AQPs) animales correspondent à des candidats pertinents. Dans ce contexte, les objectifs de la thèse étaient de déterminer si les AQPs sont per-méables au Si et, le cas échéant, de caractériser le rôle physiologique du trans-port en Si par les AQPs et d’identifier des résidus qui permettent à ces canaux d’agir ainsi. Nos travaux ont permis de constater que les AQP3, AQP7, AQP9 et AQP10 humaines, connues sous le nom d’aquaglycéroporines (AQGPs), peuvent toutes agir comme des transporteurs de Si ou plus spécifiquement de l’acide or-thosilicique qui permet à l’atome d’exister sous forme soluble. Le transport obser-vé est de nature michaelienne, sensible à la phlorétine (AQP7 et AQP9) mais in-sensible aux changements de pH et d’osmolalité extracellulaire. Aussi, la distribu-tion tissulaire de ces transporteurs concorde avec celle du Si, et l’expression des AQP3, AQP7 AQP9 dans le petit intestin de la souris est augmentée avec une diète faible en Si. Par ailleurs, nous avons démontré que la région des AQPs connue sous le nom de filtre aromatique/Arginine joue un rôle important dans la sélectivité à l’OSA, et que les résidus L84 chez AQP1 et N208 chez AQP10 jouent un rôle dans la sélectivité à l’eau et au Si respectivement. Ces travaux ont mené à la première description de transporteurs de Si chez l’animal, et à une meilleure compréhension de la physiologie de l’atome chez les mammifères.
The subject of this Ph.D. thesis is the transport of silicon (Si) by animal aqua-porins. Si is an abundant element in nature where it plays important roles, namely in plants. It also appears to play important physiological roles in animal physiolo-gy, by contributing to bone integrity, tegumentary health and collagen mainte-nance. Even though Si transporters have already been identified in diatoms and plants, none have been described in animals thus far. However, compartmentali-zation of Si throughout the mammalian body and nutritional assimilation suggest the existence of such transporters. Given the homology that they share with the Si transporters of plants, the mammalian aquaporins (AQPs) correspond to relevant candidates. In this context, the thesis’ objectives were, to determine whether AQPs are permeable to Si, and if so, to characterize the physiological role of Si transport by the AQP and to identify residues that allow these channels to act as such. Our work has allowed us to observe that human AQP3, AQP7, AQP9 and AQP10, also known as aquaglyceroporins (AQGPs), can all act as transporters for Si or more specifically for orthosilicic acid (OSA) that allow Si to be soluble in this form. The observed transport is michaelian in behavior, sensitive to phloretin (AQP7 and AQP9), but insensitive to changes in pH and extracellular osmolality. Also, tissular distribution of these carriers concords with that of Si, and expression of AQP3, AQP7 and AQP9 in the small intestine of mice is upregulated through a Si-poor diet. Otherwise, we have demonstrated that the region within the AQP that is knows as that aromatic/arginine filter (ar/R) plays an important role in OSA selec-tivity, and that residues L84 in AQP1 and N208 in AQP10 plays an important role in water permeability and Si permeability respectively. These results have led to the first description of Si transporters in animals, and a better understanding of the role played by this atom in mammalian physiology.

Full textVisual phototransduction involves many proteins including phosphodiesterase, which leads to photoreceptor hyperpolarization and then signal transmission to the brain. Inactivation of the different proteins involved in this process is essential such that photoreceptors remain sensitive to changes in light intensity. In the course of this inactivation, a protein complex including R9AP (RGS9-1 Anchor Protein) inactivates phosphodiesterase (PDE). R9AP anchors a protein complex to disk membranes of the photoreceptor outer segments most likely by use of its C-terminal hydrophobic domain. Mutations in the coding sequence of R9AP lead to a visual disease called bradyopsia, which results in problems with adjusting to light variations and difficulties to follow moving objects. This disease can be caused by the loss of the membrane binding of R9AP as a result of mutations that modify the amino acid sequence of its C-terminal domain. Membrane binding of R9AP thus plays a major role in the inactivation process of PDE. However, membrane binding and structural data are still lacking for this particular protein. We have thus initiated the characterization of the structure and membrane binding of R9AP, including the fulllength protein, R9AP without its C-terminal domain (R9AP∆TM), as well as its Cterminal domain alone. In order to get pure R9AP, we have cloned, overexpressed and purified R9AP∆TM in fusion with solubility-enhancing/purification tags. Recombinant proteins were expressed using a bacterial expression system. This study allowed us to develop a procedure to obtain pure R9AP∆TM as well as to significantly improve our understanding of the use of fusion proteins. Indeed, we have performed a systematic analysis of the impact of the design of fusion proteins on their solubility, expression and purification. This study was the first one to evaluate the effect of both the identity and the position of the tags on the solubility, expression and purification of proteins of interest. Also, the production of R9AP∆TM recombinant proteins allowed us to identify an alternative translation initiation site in the coding sequence of the GST (glutathione S-transferase) tag, which results in the expression of a truncated fusion protein. This finding will certainly have an important impact when considering the extensive use of the GST tag. Results have shown that the R9AP∆TM protein is much more soluble than the fulllength protein, which suggests a major role of the C-terminal domain of R9AP for its solubility. Thus, the structure and the membrane binding of R9AP∆TM have been investigated within the scope of this thesis. Infrared spectroscopy as well as circular dichroism measurements have allowed determining that R9AP∆TM as well as the C-terminal domain adopt an alpha-helical structure, which is in good agreement with both the predicted structure of R9AP and the transmembrane role of its C-terminal domain. Also, Langmuir monolayer measurements revealed that the C-terminal segment has a high affinity for most of the phospholipids found in photoreceptor membranes. In contrast, R9AP∆TM has a low affinity for these phospholipids. Thus, our results demonstrate that the membrane binding of R9AP is highly dependent on its C-terminal segment, which is consistent with its important role in anchoring the protein complex to disk membranes of the photoreceptor outer segments and in bradyopsia.
