Full textL’inflammation systémique et chronique dite « de faible intensité » est un élément clé du développement et de la progression de plusieurs désordres métaboliques tels que l’athérosclérose, le diabète de type 2 et les maladies cardiovasculaires. De plus en plus d’évidences suggèrent que l’alimentation jouerait un rôle de premier plan dans la modulation du profil inflammatoire, mais plusieurs questions demeurent non résolues à ce jour. Ainsi, l’objectif global du présent projet de doctorat était d’étudier l’impact de l’alimentation sur l’inflammation et ses mécanismes sous-jacents en utilisant trois approches expérimentales, soit 1) une approche épidémiologique, 2) une approche clinique et 3) une approche métabolique. L’alimentation a elle-même été étudiée sous différents angles incluant de simples nutriments (acides gras, dont les oméga-3), des aliments (produits laitiers) et des profils alimentaires reflétant l’alimentation dans sa globalité. En premier lieu, nous avons évalué les associations entre divers facteurs nutritionnels (oméga-3 et profils alimentaires) et le profil inflammatoire chez deux nations autochtones du Nord-du-Québec. Ces populations ont été choisies étant donné la forte et récente augmentation de la prévalence de plusieurs désordres métaboliques chez celles-ci parallèlement à un important phénomène de transition nutritionnelle. De façon globale, nos travaux démontrent que l’alimentation des Cris de la Baie-James et des Inuits du Nunavik semble exercer une influence non significative sur leur profil inflammatoire. En second lieu, nous avons réalisé une étude d’intervention nutritionnelle randomisée contrôlée portant sur l’impact de la consommation de produits laitiers sur l’inflammation ainsi qu’une revue systématique de la littérature sur le sujet. Il ressort de ces travaux que la consommation de produits laitiers dans le cadre d’une alimentation saine n’exerce aucun effet défavorable sur le profil inflammatoire. En troisième lieu, nous avons réalisé deux études d’intervention nutritionnelle randomisées contrôlées, conçues selon un devis en chassé-croisé, qui suggèrent que la consommation de divers acides gras, dont des acides gras oméga-3 d’origine marine, influence peu ou pas l’expression de gènes inflammatoires dans le sang de sujets avec obésité abdominale ou dans le duodénum d’hommes obèses et atteints du diabète de type 2. Bref, d’après l’ensemble des présents travaux, l’alimentation influencerait peu l’inflammation.
Low-grade systemic inflammation is a key etiological factor in the development and progression of several multifactorial disorders including atherosclerosis, type 2 diabetes and cardiovascular diseases. Increasing evidence suggests that diet significantly modulates the inflammatory profile. However, several questions about this topic remain unanswered at this time. The major aim of the present PhD project was to study the impact of diet on inflammation and its underlying mechanisms by using three different experimental approaches, namely 1) an epidemiological approach, 2) a clinical approach and 3) a metabolic approach. Diet also has been studied from various angles including nutrients (dietary fatty acids, such as omega-3), foods (dairy products) and dietary patterns reflecting diet as a whole. First, we assessed the associations between different nutritional factors (omega-3 and dietary patterns) and circulating inflammatory biomarkers in two Aboriginal nations from Northern Quebec. These nations were selected based on the considerable and recent increase in the prevalence of several metabolic disorders in these populations in conjunction with an important nutrition transition. Overall, our work indicates that the diet of the James Bay Cree and Nunavik Inuit populations appears to exert only a trivial influence on their inflammatory profile. Second, we conducted a randomized crossover controlled nutrition intervention study assessing the impact of dairy product consumption on inflammation as well as a systematic review of the literature on this topic. Our work suggests that consumption of dairy products as part of a healthy diet has no adverse effect on the inflammatory profile. Third, we conducted two randomized crossover controlled nutrition intervention studies which showed that the consumption of different dietary fatty acids, including omega-3 fatty acids from marine sources, exerts little or no influence on the expression of inflammatory genes in whole blood cells of individuals with abdominal obesity or in duodenal cells of obese men with type 2 diabetes. Taken together, our various works presented here suggest that diet has a minor influence on inflammation.

Full textDiet plays an important role in the development of breast cancer, but the influence of dietary factors on the mammary tissue is poorly understood. One possible underlying mechanism is the generation of oxidative stress favoring inflammation and tumorigenic processes. Consequently, antioxidant consumption that fosters tissue inflammation reduction could prevent breast cancer risk. However, few studies have explored relationships between antioxidant intakes and inflammation marker expression in breast tissue. This project aimed to evaluate potential link between the intake of antioxidants that have been associated with breast cancer risk and the protein expression level of 11 inflammatory markers in normal breast tissue of 160 women diagnosed with breast cancer. Antioxidant intakes were collected using a self-administered semi-quantitative food frequency questionnaire designed to measure dietary patterns and supplement intake over the past year. Inflammation marker expression was assessed by immunohistochemistry. Correlations between antioxidant intakes and inflammatory marker expression were explored using the Spearman’s partial correlation coefficients (r) for all women, and then for premenopausal and postmenopausal women separately. After Bonferroni correction, negative correlations were observed between dietary beta-tocopherol and IL-10 expression in all women combined (r=-0.26) and among postmenopausal women (r=-0.39). For all women, negative correlation was found between total zinc intakes and IL-10 (r=-0.26). Among postmenopausal women, dietary selenium intake was negatively correlated with the expression of lactoferrin (r=-0.39). No associations were observed in premenopausal women. Our findings suggest that consumption of specific antioxidants, including beta-tocopherol, zinc and selenium, may act on the breast tissue through mechanisms affecting the expression of certain inflammation markers and that this would be influenced by the menopausal status.

Full textEpidemiological data reported that an adequate dairy product consumption may lower the incidence of type 2 diabetes (T2D), a chronic disease which may concern 10.8 % of Canadians by 2020. Although the mechanisms underlying this association remain unclear, it has been suggested that dairy product intake may improve low-grade systemic inflammation, a key etiologic factor in the development of T2D. However, dairy products have mixed effects on inflammatory markers in clinical studies. The effect of dairy products could be mediated by the inflammatory status of the participants, as well as the nutrient composition of dairy products. Dairy products contain proteins, amino acids and fatty acids, specifically natural trans fatty acids, for which the effect on inflammation remains unclear. Furthermore, it has been demonstrated that dairy nutrients can regulate inflammatory gene expression. Nevertheless, a mechanistic approach is required to elucidate the role of dairy products on inflammation and the prevention of T2D. Accordingly, we tested the hypothesis that the effect of dairy products on inflammation was influenced by the inflammatory status of the individuals and the macronutrient composition of dairy products. Therefore, the main objective of this thesis was to evaluate the contribution of those two factors on inflammation. Firstly, dietary, anthropometric and biochemical data from two cohorts of individuals recruited in Quebec City were assessed. Results show that dairy product consumption is inversely correlated with glycaemia and blood pressure in healthy individuals. Dairy intake is also slightly correlated with plasma C-reactive protein (CRP) concentrations, without influencing other inflammatory markers (tumor necrosis factor alpha (TNF-α) and interleukin 6 (IL-6)). Moreover, concentrations of dairy trans fatty acids in plasma phospholipids are associated to high-fat dairy product consumption, as well as favorable adiponectin levels and blood pressure. Secondly, we developed cell models, with or without induction of inflammation with TNF-α, to identify bioactive dairy nutrients. Cells were incubated for 24 hours with individual or combinations of dairy trans fatty acids, proteins or amino acids. Dairy trans fatty acids and dairy protein compounds do not influence inflammatory gene expression in healthy cells. Oppositely, dairy trans fatty acids, whey proteins and their major amino acids (leucine, isoleucine and valine) decrease inflammatory gene expression in TNFα-stimulated endothelial cells. Dairy trans fatty acids also lower prostaglandin excretion; yet they increase F₂-isoprostane levels in cell supernatants. Moreover, dairy trans fatty acids are highly incorporated into cell membranes, which modifies fatty acid profiles and possibly impairs the function of membrane receptors. Finally, co-incubation of dairy trans fatty acids and dairy protein compounds have neither an additive nor a synergic effect on inflammatory gene expression and eicosanoid levels in endothelial cells. The present work suggests a beneficial impact of dairy trans fatty acids and whey proteins on inflammation. Further, the anti-inflammatory effect of these nutrients appears only in inflamed cells, which favors the hypothesis that dairy products may positively impact inflammation according to the inflammatory status of the individuals. The cellular approach is a useful tool to investigate the impact of the different sources of variability regarding inflammatory response to dairy products. Further investigations in vivo are required to validate the major sources of variability in animal models or in humans.

Full textVisceral obesity has been identified as the main cardiovascular disease risk factor that contributes to insulin resistance. Bad eating habits and sedentary lifestyle can contribute to obesity, but can also affect independently and unfavourably the metabolic and vascular insulin actions. The aim of this research project was to determine the impact of a high fat high sucrose diet (HFHS) on endothelial function as well as the establishment of an oxidative stress and inflammatory response in an animal model of dietary-acquired insulin resistance and obesity. Precisely, the objective of chapter 2 was to develop a new animal experimental model, the rat fed with a diet rich in saturated fat and refined sugar, representative of the high-energy diets frequently consumed by a large percentage of North American. The aim of chapter 3 was to determine the effects of a preventive treatment with an antioxidant, tempol, on endothelial function as well as glucoregulatory and hemodynamic actions of insulin in this animal model. The objective of chapter 4 was to study the effects of HFHS diet and tempol on the expression and activity of markers of insulin signalling pathways, oxidative stress and inflammation. We noted that the HFHS diet altered the endothelium-dependent vasodilation, decreased insulin-stimulated glucose transport and insulin sensitivity as well as reduced expression and activation of many insulin signalling pathway proteins. We also identified oxidative stress or inflammatory markers that could contribute to endothelial function degradation and take part in vascular and metabolic complications induced by the HFHS diet, in the rat. We demonstrated that many of those alterations could be avoided, attenuated or prevented by an early intervention aimed at controlling oxidative stress. This research project provided a better understanding of the implication and the link between endothelial NO and the oxidative stress as well as the inflammation induced by a HFHS diet, in an animal model of diet-induced insulin resistance and obesity.

Full textInflammation is the basic mechanism of the immune system. In the case of inflammatory pathologies this inflammation persists and becomes deleterious to the organism. Many reasons can explain this persistance. One of these causes is the presence of inflammatory-inducing molecules. They may have exogenous origin such as PAMP (Pathogen Associated Molecular Pattern). They are derived from pathogens (LPS, peptidoglycans, CpG DNA ...), and are able to activate the immune system. These molecules can also have endogenous origin such as the DAMP (Damage Associated Molecular Pattern). They are released by stress cells (HMGB1, HSP60, S100 ...) to prevent and activate the immune system. The presence of receptors (TLR2, TLR4, RAGE ...) capable of recognizing these PAMPs and DAMPs is also necessary in order to elicit inflammation.My work explores the contribution of PAMPs and DAMPs to inflammatory diseases at molecular and cellular levels. To this end, my study focuses on recognition and induction of inflammation by PAMPs and DAMPs.We have thus demonstrated cellular and molecular mechanisms in the inflammatory response related to DAMP and PAMP. We were also interested in the receptors involved in these mechanisms and even showed a new potential receptor. We hypothesize that CD93 may have a role in inflammatory pathologies by his ability to bind DAMPs and PAMPs. Thus CD93, HMGB1, HSP60 and LPS could be potential therapeutic targets concerning inflammatory diseases

Full textBreast cancer (BC) represents one of the most common and dangerous cancers in terms of mortality and incidence among women worldwide. It is even more recurrent in developed countries including Canada [2]. BC is a complex and multifactorial disorder, its severity and response to treatment differs from case to case and its diagnosis can be tricky due to the heterogeneity of the pathology. Thus, this project aims to study a potential BC risk factor that can be used for diagnosis and treatment of BC patients. Allograft Inflammatory Factor-1 (AIF1) is a protein involved in many inflammatory diseases that has also been associated with cancer, however, in most studies, only one isoform has been analyzed. Our analyses of the transcriptional profile of individuals from French Canadian families with high risk of BC (BRCA1/BRCA2 or not-BRCA1/2 (BRCAX)) identified significantly and differentially expressed transcripts between the different groups. Among them, two AIF1 splice variants were highly overexpressed in the BRCAX lymphoblastoid cell lines (LCLs) of the affected sister comparatively with her non-affected sister. Our gene expression analysis revealed that both isoforms were mostly expressed in the least aggressive BC and this expression resulted from the tumor microenvironment, AIF1v1 being mostly expressed by lymphocytes and AIF1v3 by activated macrophages. We also demonstrated the effect of docosahexaenoic omega-3 fatty acids (DHA) on the downregulation of AIF1 isoforms expression in BRCAX LCLs. Lastly, our data showed that AIF1 isoforms expression in breast tumors and breast adipose tissue correlated with metabolic and clinical parameters of BC patients. Ultimately, all data and information resulting from this study represent a major breakthrough for the scientific community and the cancer research field since it is the first study on AIF1v1 and its involvement in BC, breast tumor microenvironment and inflammatory reaction.

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.
