Full textProstate cancer (PCa) is the most frequently diagnosed cancer in Canadian men with 21,300 new cases and is the third-largest cause of cancer mortality with 4100 deaths in 2017. Epidemiological studies have shown that populations with a diet rich in omega (ω)-3 fatty acids(FA) (e.g. coastal Asian populations) have a low incidence of PCa while populations in Western countries with a diet rich in ω6 FA have higher (almost 60 times) incidence of PCa. Dietary fats influence many biological processes including inflammation which is associated with PCa development and progression. Notably, long-chain ω6 FA (LCω6) have pro-inflammatory properties and could contribute to PCa progression. On the opposite, LCω3 such as eicosapentaenoic acid (EPA) and docosahexanenoic acid (DHA) have anti-inflammatory properties and could inhibit PCa progression. I hypothesized that dietary ω3 FA are beneficial against PCa growth and progression mainly via their anti-inflammatory properties. Using the TRAMP-C2 mouse model of PCa, I found that an ω3 FA-enriched diet reduced PCa growth compared to an ω6 FA-enriched diet in both androgen-deprived and non-deprived mice by inducing local antitumor Th1-, Th2-and eosinophil-related immune response. In the quest to further study the effects of individual ω3 FA subtype, I found that dietary supplementation with monoacylglyceride (MAG)-EPA reduced tumor growth by inhibiting vascular endothelial growth factor (VEGF)and vascular endothelial growth factor receptor-2gene (VEGFR2)expression as well as reducing the size of blood vessels in TRAMP-C2 tumors. I also observed that higher level of EPA reduced the size of blood vessels in prostate in a clinical trial testing MAG-EPA supplementation on PCa patients undergoing radical prostatectomy. Finally, I analyzed the effects of an ω3 FA-rich diet intervention versus treatment with a 5α- reductase inhibitor (5ARI) on low-risk PCa patients under active surveillance. I found that 6 months of ω3 FA-rich diet intervention resulted in a reduction of plasma level of pro-inflammatory and pro-angiogenesis cytokines as well as Th2 and Th17 immune response-related cytokines. In order to assess the effects of these interventions on the prostate tissue, I used cytokines assay and mass spectrometry (MS ) assay to analyze proteins in clarified urine obtained after digital rectal examination (DRE urine). I did not succeed at identifying significant variation in protein levels following the interventions in this sample type but I found that crude (non-clarified) DRE urine contained twice the amount of proteins compared to clarified urine, suggesting that this type of sample should be used for further analysis. Overall, my results confirmed the importance of ω3 FA for prevention of PCa progression and provide the rationale to further investigate their effects on immune response, tumor vasculature and tumor progression in PCa patients.

Full textL’objectif principal des études présentées dans cette thèse était d’étudier les effets physiologiques et mécanistiques d’une fraction de peptides de saumon (SPF) de faible poids moléculaire (molecular weight, MW) combinée ou non avec une huile riche en oméga-3 (fish oil, FO), dans un contexte d’obésité induite par une diète riche en gras et en sucre (high-fat and sucrose diet, HFS). Le modèle de souris utilisé en était un du syndrome métabolique (metabolic syndrome, MetS), la souris LDL-/-/ApoB100/100. Dans l’étude de 3 mois (JN, 2015), nous avons montré que les souris nourries avec le SPF ou à la combinaison (SPF+FO) étaient plus tolérantes au glucose. Elles présentaient également des améliorations de plusieurs conditions généralement associées avec le MetS, soit un meilleur profil lipidique, une diminution de l’inflammation du tissu adipeux épidydimaire et une amélioration de la voie de signalisation de l’insuline hépatique. Ces effets étaient associés à une légère diminution du poids corporel, du poids du foie et de l’efficience alimentaire. Les effets observés in vivo du SPF ont ensuite été validés dans 3 lignées cellulaires. Deuxièmement, nous avons voulu valider les effets du SPF au niveau de la tolérance au glucose après 3 mois de diète. Puis, nous avons exploré les mécanismes derrière les effets bénéfiques du SPF et du FO en analysant le métabolome plasmatique des acylcarnitines (AC) et l’expression de gènes hépatiques. Les niveaux d’adiponectine ainsi que l’expression de plusieurs gènes impliqués dans l’homéostasie du glucose, des lipides, dans l’inflammation et dans la β-oxydation mitochondriale et peroxisomale étaient modulés par le SPF et le FO. Le profil en AC a démontré plusieurs changements causés par le SPF et le FO autant au niveau des AC à courte chaîne qu’à moyenne et longue chaîne. Troisièmement, nous avons une fois de plus validé les effets du SPF au niveau de la tolérance au glucose, mais sur une période de 6 mois. Nous nous sommes concentrés sur le profil métabolomique des acides aminés (AA) plasmatiques et avons tenté de comprendre les changements importants survenus après 6 mois de diète en faisant l’analyse par immunobavardage des protéines et enzymes régulant le catabolisme des acides aminés à chaîne ramifiée (branched-chain amino acids, BCAA). L’utilisation du plasma obtenu au sacrifice à l’état de jeûne et post prandial de notre cohorte de souris nourries pendant 3 mois nous a permis d’évaluer l’association entre la signature métabolomique des AA et les effets physiologiques du SPF. Ces études démontrent le potentiel du SPF jumelé ou non avec le FO dans la prévention de complications reliées à l’obésité, comme l’intolérance au glucose, l’inflammation de bas degré et la dyslipidémie.
The main objective of this thesis was to evaluate the metabolic and mechanistic effects of a low-molecular-weight salmon peptide fraction (SPF) combined or not with omega-3-rich fish oil (FO) in the context of diet-induced obesity (DIO) in a murine model of the metabolic syndrome (MetS), the LDL-/-/ApoB100/100 mouse. In the first study, we have shown that mice fed the SPF alone or in combination with FO (SPF+FO) were more glucose tolerant and had marked improvements in their plasma lipid profile, adipose tissue inflammation and hepatic insulin signaling pathway. These effects were associated with a small reduction in body weight, liver weight and energy efficiency. These in vivo effects were then validated in 3 cell lines. Secondly, we validated once again the beneficial impact of SPF on glucose tolerance after 3 months of diet. We aimed to explore its mechanisms of action by doing an extensive assessment of the acylcarnitine (AC) plasma metabolome and the hepatic gene expression of the mice. We found that adiponectin levels and many hepatic genes involved in inflammation, in glucose and lipid homeostasis and in mitochondrial and peroxisomal β-oxidation were altered with SPF and FO. The AC profile was modified upon dietary treatment with FO and SPF, with significant changes in short-, medium- and long-chain AC. Thirdly, we validated the beneficial effects of SPF on glucose tolerance over a 6- month period, and decided to concentrate on the metabolomic profile of plasma amino acids (AA). We aimed to understand the important alterations that occured after 6-months on diet in the SPF-fed animals. Then we also looked at changes in the proteins and enzymes regulating branched-chain amino acids (BCAA) catabolism in liver, skeletal muscle and epidydimal adipose tissue by Western blotting. The metabolomic analyses of plasma obtained after 3 months of diet in our other cohort of mice gave us the opportunity to evaluate the association between the AA signature and the physiological effects of SPF. These studies show the potential of SPF combined or not with FO as a nutraceutical for the prevention of obesity-related complications, such as glucose intolerance, low-grade inflammation and dyslipidemia.

Full textTrans n-3 polyunsaturated fatty acids (PUFA) are formed during heat treatment of vegetable oils. In this work, we demonstrated that feeding rats and piglets with a diet in which a part of 18:3 n-3 is present as trans isomers lead to a "deficiency-like" status in n-3 PUFA in phospholipids of the retina and the frontal cortex. These changes in lipid composition were associated to a decrease of the b-wave amplitude of the electroretinogram (ERG) and to an increase of the levels of the dopaminergic neurotransmitters, respectively. Nevertheless, these results showed that trans n-3 PUFA and/or the n-6/n-3 ratio could act on the visual function and the dopaminergic neurotransmission by inducing a 30%-decrease of the b-wave amplitude of the ERG and a depletion of dopamine levels in the hippocampus. These results suggest that it would be better to prevent the presence of trans n-3 PUFA in the Human diet
