Full textLe trouble majeur de la dépression est un des troubles de santé mentale les plus fréquents dans la société d’aujourd’hui avec plus de 350 millions de personnes atteintes dans le monde. Malgré la présence de différents types de traitement, comme les antidépresseurs ou les thérapies comportementales, les causes de ce trouble ne sont pas encore complètement élucidées. Les lacunes concernant la compréhension de cette pathologie se trouve plus particulièrement au niveau de ses fondements génétiques. A partir d’un grand échantillon de 267 sujets atteints de la dépression, de 286 sujets témoins ainsi que de trois modèles animaux, la présente étude a pour objectif de mettre en évidence différents gènes et fonctions associés de façon significative à cette maladie et de caractériser les différences transcriptionnelles spécifiques au sexe. Pour ce faire, deux grandes étapes composent ce projet. Une analyse de gènes différentiellement exprimés ainsi qu’une de modules de gènes Eigengenes, toutes deux effectuées sur l’humain et sur les modèles animaux. Les résultats ont mis en exergue plusieurs gènes associés à la dépression et partagés entre l’humain et les modèles animaux. Il semblerait que le modèle animal qui reproduit le plus les observations chez l’humain soit celui de l’isolation sociale. De plus, plusieurs fonctions biologiques pertinentes avec la caractérisation du trouble étudié ont été identifiées. Par surcroît, les modules de gènes associés à la dépression chez les femelles étaient en plus grand nombre que chez les mâles et cette observation est bien reproduite dans le modèle du stress variable chronique de l’animal. Cette étude a donc permis une amélioration des connaissances concernant la génétique de la dépression. Il en ressort que les modèles animaux utilisés dans cette étude permettent de bien de reproduire un état dépressif chez l’animal.
Major depressive disorder is one of the most common mental health disorder in modern society affecting more than 350 million people worldwide. While different types of treatment are available, such as antidepressants or behavioural therapies, causes of this disorder are not yet fully understood. A better comprehension of its genetic basis could fulfil the gaps. From a large sample of 267 subjects with depression, 286 control subjects and three animal models, this study aims to identify different genes and functions significantly associated with this disorder and to characterize sex-specific transcriptional differences. This project splits in two major steps: a differentially expressed genes analysis and a gene modules analysis using Eigengenes, both performed on humans and animal models. Results highlight several genes shared between humans and animal models. The animal model that seems to better reproduce the effects observed in humans is that of social isolation. In addition, several biological functions appear to be relevant to major depressive disorder characterization. Furthermore, gene modules associated with depression are more numerous in females than in males and this observation is reproduced in the animal’s chronic variable stress model. This study therefore enhanced knowledge about depression’s genetics and shows that animal models can be effectively used to reproduce a depressive state in animals.

Full textCysinosis is an inherited disorder due to mutations in the CTNS gene, encoding a lysosomal transporter of cystine, cystinosin. Abnormal cystinosin leads to an intralysosomal accumulation of cystine which is associated with major kidney defects and multisystemic disease. We have shown that CTNS-/- fibroblasts contain decreased glutathione levels which can be replenished by cysteine precursors. In addition these cells are subject to oxidative stress, as demonstrated by the induction of superoxyde dismutase. We failed to detect such defects in Ctns-/- mouse proximal tubular cells that we generated and characterized. In addition two different congenic Ctns-/- strains were generated on C57BL/6 and FVB/N genetic backgrounds. Although both strains accumulate cystine, only the C57BL/6 Ctns-/- mice present with renal symptoms that partially mimic those observed in patients. Therefore these mice should be useful to test new therapeutic approaches

Full textThe numerous advantages of zebrafish were used to study two hereditary diseases: desminopathy and pulmonary veno-occlusive disease (PVOD). Desminopathy is a myofibrillar myopathy characterized by the presence of granulofilamentous aggregates. Two models of loss and gain of function of desmin showed the implication of both loss of functional desmin and presence of desmin aggregates in desminopathy clinical manifestations. Phenotypes observed in these models include in particular a perturbation of the heart contraction biomechanics and of calcium propagation throughout the myocardium. Potential drugs, lowering the aggregate content, were proposed. After validating the use of zebrafish as a model of arterial hypertension, by verifying the implication of the elasticity of the aorta in blood flow regulation, we generated and characterized PVOD models. PVOD is a rare and severe form of pulmonary hypertension. The venous-specificity of the phenotypes observed in this pathology was confirmed
