Full textEpigenetic changes associated with DNA methylation and histone modifications leading to chromatin remodeling and regulation of gene expression underlie the developmental programming of obesity, type 2 diabetes, cardiovascular diseases and metabolic syndrome. This review focuses on converging data supporting the hypothesis that, in addition to "thrifty genotype" inheritance, individuals with obesity, type 2 diabetes, and metabolic syndrome (MetS) with an increased risk of cardiovascular diseases have suffered improper "epigenetic programming" during their fetal/postnatal development due to maternal inadequate nutrition and metabolic disturbances and also during their lifetime, that could even be transmitted to the next generation(s). We highlight the susceptibility of epigenetic mechanisms controlling gene expression to environmental influences due to their inherent malleability, emphasizing the participation of transposable elements and the potential role of imprinted genes during critical time windows in epigenetic programming, from the very beginning of development, throughout life. Increasing our understanding on epigenetic patterns significance and their role in development, evolution and adaptation and on small molecules (nutrients, drugs) that reverse epigenetic (in)activation should provide us with the means to "unlock" silenced (enhanced) genes, and to "convert" the obsolete human thrifty genotype into a "squandering" phenotype

Full textThe metabolic syndrome is a cluster of interrelated cardiovascular risk factors co-occurring in the same individual. People with this syndrome are at increased risk for developing diabetes mellitus and cardiovascular diseases. Accordingly, it is important to elucidate the genetic aetiology governing this trait in order to better comprehend its pathogenesis. In the present thesis, heritability and complex segregation analyses as well as candidate gene and genome-wide scan approaches have been applied to shed some lights on the genetic architecture of the metabolic syndrome and its individual components. A total of three candidate genes have been investigated including peroxisome proliferator-activated receptor (PPAR) α and PPARγ as well as phospholipid transfer protein (PLTP). It has been shown that polymorphisms in both PPARα and PLTP genes are significantly associated with several indices of adiposity. In addition, significant gene-gene interactions have been observed between PPARα and PPARγ on glucose/insulin parameters. It has also been shown that the HDL2-cholesterol response to gemfibrozil therapy is modulated by the PPARα L162V polymorphism. Genome-wide linkage scans have been performed on lipid and lipoprotein concentrations. Many chromosome regions harbouring lipoprotein/lipid genes have been identified including 1q43, 11q13 q24, 15q26.1, and 19q13.32 for LDL-cholesterol, 12q14.1 for HDL-cholesterol, 2p14, 11p13, and 11q24.1 for triglycerides, 18q21.32 for LDL-apolipoprotein (apo) B, and 3p25.2 for apoAI. The genetic contribution of the variation in LDL peak particle diameter (LDL-PPD) has been also investigated. Overall, the results indicate: 1) that LDL-PPD strongly aggregates within families with heritability estimate above 50%; 2) the existence of a major gene effect affecting the phenotype; and 3) the presence of a major quantitative trait locus located on chromosome 17q. The apo H gene, a positional candidate gene, was then significantly associated with LDL-PPD, suggesting that this gene is responsible for the linkage signal observed on 17q. Finally, factor analyses have been used to construct a quantitative metabolic syndrome variable and a genome-wide linkage scan has been conducted to identify the genomic regions underlying this trait. A major quantitative trait locus has been observed on chromosome 15q suggesting a gene within this region contributing to the clustering of the metabolic syndrome-related phenotypes. Many of these findings must go through independent replication, while others produced new leads that deserve follow-up.

Full textObesity is now a major problem worldwide. Its associated morbidity is mostly related to the components of metabolic syndrome (MetS), a constellation of risk factors including hypertension, dyslipidemia (low HDL-C concentration and high concentration of TG), hyperglycemia and obesity. However, some obese subjects remain metabolically healthy. Genetic has thus been established as playing a major role in the development of obesity and its complications. Epigenetic factors may also be involved. The analysis of visceral adipose tissue (VAT) was thus done and led to the discovery of several differentially expressed and methylated genes between groups of obese affected and unaffected with MetS. The two candidate genes NMT1 and DGKZ were part of these and their associations with components of MetS were tested, as well as their methylation and expression levels.

Full textPreeclampsia (PE), a pregnancy complication characterized by increased blood pressure and proteinuria, is associated with significant maternal and neonatal mortality and morbidity worldwide. Recent studies suggest that women who suffered from PE are at increased risk of long term cardiovascular diseases (CVD) and that the link between these two entities could be explained by the metabolic syndrome (MS). As inflammation appears to be a major element involved as much in PE than in MS and CVD, our research aimed to investigate the potential association between genetic variations in candidate genes involved in the inflammatory process and PE risk in a study sample that included 307 women who suffered from PE and 603 matched controls. In this regard, we analysed known polymorphisms of interleukin-1α (IL-1α; 4845G>T), interleukin-6 (IL-6; -174C>G), interleukin-10 (IL-10; -1082A>G, -2849G>A), TNF-α (TNF-α; -308G>A, -857C>T) and TNF-α receptors (TNFRІ 36A>G, TNFRІІ 676T>G) genes. Our results suggest the presence of a dose-effect of the combination of genes involved in the inflammatory process on the risk of PE.

Full textThe sequence of molecular events through which alterations in externals cues may impinge on circadian clocks, and generate pathologies, was mostly unknown. During my thesis work, I have molecularly deciphered, how switching feeding in mice, from the “active” to the "rest" phase [Restricted Feeding (RF)] , alters the metabolism through hypoinsulinemia during the “active” phase, leading to increased PPARα activity, thereby reprograming both metabolism and RevErbα expression and leads to a 12h circadian clock-shift in peripheral tissues.Most notably, the lack of PPARα expression in the suprachiasmatic nuclei (SCN) prevents a shift of the central clock. Therefore, the “active” and “rest” phases controlled by the SCN clock and gene expression controlled by the peripheral circadian clocks are misaligned. Most interestingly, this misalignment generates a metabolic syndrome-like pathology, similar to that associated with shiftwork schedules

Full textLowe's syndrome is a rare X-linked recessive genetic disorder associated with loss of function mutations in the OCRL gene. It is characterized by congenital cataract, proximal renal tubulopathy and neurological signs. Currently, the pathophysiology of neurological signs is still unclear. My thesis focuses on the study of cellular and molecular bases of neurological signs of Lowe's syndrome.We began by mimicking the pathology in vitro using neurons from the mouse hippocampus where we inhibited OCRL expression. We investigated the consequences of this loss on neuronal phenotypes reported in various models of intellectual disability. We also explored primary cilia formation during in vitro differentiation. We then analyzed the role of OCRL1 in mouse cortical brain formation using in utero electroporation of shRNA in the brain of mouse embryos.We identified different phenotypes disrupted by the loss of OCRL expression in Lowe's syndrome. Neurons inhibited for OCRL are on average smaller with fewer branches and a less complex arborization. This lack of dendritogenesis suggests that OCRL plays a role in dendritogenesis. By studying precisely the dendrites, we observe a dysregulation of the formation of dendritic spines associated with a defect of synaptogenesis.When OCRL is inhibited, there is a defect in ciliogenesis. This primary cilia defect is also reflected in vivo by a delay in the cortical migration of neurons inhibited for OCRL. Thus OCRL also has a role in neurons ciliogenesis.These abnormalities thus constitute cellular and molecular bases of the pathophysiology of the neurological signs of the disease.OCRL mutations were observed not only in patients with classic Lowe's syndrome, but also in patients with more moderate disease (almost no neurological and ocular signs), classified as Dent-2. Other patients present an intermediate symptomatology between the two pathologies showing the existence of a clinical continuum between Dent-2 disease and Lowe's syndrome. This situation suggests that there are individual differences in the ability to compensate for the loss of enzymatic function. Despite numerous studies, the mechanisms leading to restricted clinical manifestations are still poorly understood.The second part of my thesis explores the compensation mechanisms existing between Lowe and Dent-2 patients.Studies in the laboratory have shown that fibroblasts from Lowe and Dent-2 patients have different phenotypes and identified a gene, PLCβ1, as being differently expressed in Lowe and Dent patients. PLCβ1 being involved in the same metabolic pathways as OCRL. We therefore investigated phenotypes of Lowe patient’s fibroblasts that were less severe in Dent-2 patient’s fibroblasts. Inhibition of PLCβ1 in Lowe patient’s fibroblasts allowed us to observe that the fibroblasts have a "Dent-2 type phenotype". Reciprocally, when overexpressing PLCβ1 in Dent-2 fibroblasts, we found that the fibroblasts exhibit a "Lowe-like phenotype".This work suggests that PLCβ1 is a modifier gene of Lowe's syndrome, and that it has a role in the heterogeneity of the neurological signs associated with OCRL mutations. My project was to evaluate PLCβ1 as a modifier gene of Lowe's syndrome. We tested this hypothesis, by modulating PLCβ1 in neurons downregulated for OCRL. Neurons both inhibited for OCRL and PLCβ1, have phenotypes almost similar to controls for all the parameters we studied previously. The modulated neurons for both OCRL and PLCβ1 are on average larger with more branches and a more complex arborization than the neurons KO for OCRL. We observe a restoration of the density of the dendritic spines and synapses, a denser actin network and an improvement of the ciliogenesis defect.All these results confirm the hypothesis of the involvement of PLCβ1 in the phenotypic variability of neurological signs between Lowe syndrome and Dent-2 disease, and that PLCβ1 is a modifier gene of Lowe's syndrome
