Full textThe physiological and cellular metabolism and functions of the saturated fatty acids are not yet wellknown. Therefore, it is necessary to study saturated fatty acids separately to improve the knowledge about them. Among them, we are particularly interested in studying myristic acid, which is able to regulate several metabolic pathways by acylating proteins. This is the N-terminal myristoylation. To study thoroughly the effects of saturated fatty acids and myristic acid on the organism, physiological and molecular experiments have been realized during this thesis. The first epidemiological studies described in the literature showed that dietary saturated fatty acids, supplied in excess, had negative effects for health because they were positively correlated with the increase of the mortality due to the cardiovascular diseases. However, no negative association was observed when they are supplied at moderated quantities. Our results showed that diets supplemented with butterfat (which supply moderate quantity of saturated fatty acids, less than 10% of the total energy intake) significantly decrease cholesterolemia in the rat, compared to diets with olive oil, known as neutral concerning the cardiovascular diseases. Moreover, the butterfat improves the bioavailability of the n-3 and n-6 polyunsaturated fatty acids of rat tissues. We have however not identified the saturated fatty acid of the dairy fat which is responsible for these positive effects in the rat. Myristic acid is able to regulate many cellular mechanisms by the myristoylation of proteins. First, we evaluated its impact in the sphingolipid biosynthesis by studying the dihydroceramide 4-desaturase (DES) in cultured rat hepatocytes. Our results showed that, among the tested fatty acids, myristic acid only increases, weakly but significantly, the native DES activity. This effect is probably due to the myristoylation of DES and has for consequences to induce apoptosis. Then, we investigated new myristoylated proteins, to discover other metabolic pathways which could be regulated by myristic acid. The study reveals the myristoylation of an enzyme which is involved in the ubiquitine-proteasome system: the E3-ligase, named Mahogunin ring finger 1 (MGRN1). Our results showed that there are two isoforms of MGRN1 in the rat: MGRN1(-12)S and MGRN1(+12)S, which are both myristoylated in vivo. The effects of the myristoylation on its function are still preliminary results. But, we showed that the myristoylation could modify the subcellular localization of MGRN1, because the recombinant wild-type myristoylable form seems to be excluded from the nucleus, whereas the mutated non-myristoylable form is mainly in this organelle. The results obtained during this thesis show the physiological and cellular functions of the saturated fatty acids, and particularly the importance of the myristic acid in essential pathways of cellular regulations, through its function of myristoylation.

Full textSaturated fatty acids (SFA) have been reported to alter organelle integrity in many cell types. This process, also known as lipotoxicity, has been proposed to be responsible for several human pathologies such as type 2 diabetes.At the cellular level, SFA accumulation is associated with an increase of the saturation rate of membrane phospholipids (PL), the major components of organelle membranes, and an increase of ceramides levels, implicated in apoptosis induction.In the first part of this work, we took advantage of a simple yeast-based model to study the relative contributions of saturated PL and ceramides to SFA cytotoxicity. We demonstrated that ceramides act early in the secretory pathway, while saturated PL impact the later steps, and particularly the formation of secretory vesicles.In parallel, we observed that SFA amounts were significantly increased in the membrane PL of cystic fibrosis (CF) patient cells. The most common mutation responsible for this genetic disease results in the retention of the corresponding protein in the endoplasmic reticulum. Pharmacological agents, which correct the mistrafficking of the protein, have been isolated in vitro, but they did not show significant improvements in clinical trials. We propose in the present manuscript, that SFA-related lipointoxication could be an important bottleneck for the use of these pharmacological agents in clinical trials

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.
