Full textSeveral studies have reported that some kinases located in the liver respond to the availability of amino acids. These kinases are mammalian target of rapamycin '(mTOR), "adenosine monophosphate-activated protein kinase" (AMPK) and "general control non-depressible kinase 2" (GCN2).The aim of our study was to clarify the role of two of these signaling pathways, AMPK and GCN2 in the adaptations of energy and protein metabolism in response to the modulation of dietary protein content. Wild-type and liver AMPK-deficient or liver GCN2-deficient mice were fed either a low, a normal or high protein diet during three weeks. Analyzes showed that liver AMPK-deficient mice fed under a normo-protein diet exhibit an adapatation of liver metabolism and secret FGF21 which enables them to have normal postprandial oxidation profiles.In contrast, liver AMPK-deficient mice fed a low or a high protein diet exhibit an alteration in postprandial oxidation profiles. The deletion of GCN2 in the liver only has an effect under low protein diet as liver GCN2 deficient mice have a lower lipid oxidation and a higher carbohydrate oxidation linked to the absence of FGF21 secretion. Concerning protein metabolism, AMPK and GCN2 do not seem to be involved in protein synthesis rate in the posrprandial period in the liver and periphery in the postprandial muscle. In conclusion, these studies show that hepatic AMPK and GCN2 deletions affect energy metabolism, but not protein metabolism and that the consequences depend on diet composition

Full textOleoylethanolamide (OEA) is a lipid derivative involved in food intake control and body weight gain management through the activation of several receptors such as PPAR-α. OEA effects have been demonstrated after intraperitoneal administration or on isolated cells. The aim of this research project was to study the efficiency of oral OEA with a chronic administration. An experimental model was designed to study OEA effects with a nutritional perspective. Oral OEA administration induced a decreased body fat deposition and a lower food intake. These effects were associated to the modulation of genes such as intestinal GPR119 and adipose FAAH. Other genes involved in lipid metabolism and also in β- oxidation were affected. At a physiological level, an increase of energy expenditure and lipid substrate oxidation was observed, and it was partially associated to a higher spontaneous activity. The non-hydrolysable analog study showed that OEA degradation was not sufficient to decrease its measured biological effects. In addition, we observed that a bolus administration of OEA could modulate AEA (orexigenic) plasma kinetics, this phenomenon could contribute indirectly to satietogenic effects of OEA. This research project has been performed in a nutritional aim, considering OEA as a putative bioactive ingredient. This PhD project belongs to the actual problematic concerning the use of FAEs for body weight management

Full textAccurate measurements of physical activity in free living are needed to establish what dose of physical activity is necessary for obtaining a specific health benefits. The first aim of this work was to validate the Actiheart (which combines heart rate and accelerometry sensors) with doubly labeled water (DLW). We show a good level of concordance between physical activity energy expenditure (PAEE) estimated by Actiheart and DLW. Individualization of the relationship between heart rate and PAEE by an incremental test is needed for an accurate estimate of the PAEE at the individual level and to evaluate changes induced by an intervention. In laboratory, we show that the accuracy of Actiheart is activitydependent. This requires the establishment of their recognition from new sensors and mathematical models. Adiponectin, hormone secreted by adipose tissue, has a role in energy metabolism and its secretion decreases with obesity. However the effects of physical activity remain in contradiction in published studies. The second objective of this work was to evaluate the effect of physical activity and intervention with weight control on plasma adiponectin. We show that the total and high molecular weight adiponectin were negatively associated with modifications of the physical activity level. Further work is however necessary to understand the mechanisms underlying this modulation of plasma adiponectin which does not seem related to changes in synthesis in adipose tissue or muscle

Full textThe main substrates oxidized during prolonged exercise, whether carbohydrates, fats or proteins, do not contribute equally to the energy supply. In addition, glucose can originate from different endogenous (muscle, liver) and exogenous sources. Many factors can affect their respective contribution including: active muscle mass, training, sex, nutritional state and environmental conditions. The use of stable isotopes, such as carbon 13 (13C), combined with indirect respiratory calorimetry corrected for urea excretion in urine and sweat, allows the differentiation of endogenous and exogenous substrates and the estimation of their contribution to the energy yield. These methods, allowing the measurement of fuel selection during prolonged exercise with glucose ingestion, enabled the comparisons found in the three experimental studies part of this thesis. In the first study, fuel selection was compared during prolonged upper- and lower-body exercise with or without glucose ingestion. The difference in fuel selection between upper- and lower-body exercise when water was ingested was modest with a slightly higher reliance on carbohydrate oxidation during upper-body exercise. The amount of exogenous glucose oxidized was lower but its contribution to the energy yield was higher during upper-body exercise due to the lower energy expenditure. In the second study of the thesis, the effects on fuel selection in women and men of a diet rich in carbohydrate and glucose ingestion during prolonged exercise were compared. It is generally recognized that for a given relative workload, women rely less on carbohydrates and more on fat than men. The separate effects of a diet rich in carbohydrates or glucose ingestion during exercise on fuel selection were indeed similar in men and women. However, the combined effects of both procedures were larger in women than in men, supporting the suggestion that a small carbohydrate deficit could be present in women. In the third study, substrate oxidation and particularly that of exogenous starch during prolonged walking at a low workload was described. Subjects engaged in prolonged exercise at low workload (<40 %VO2max) are encouraged to ingest carbohydrate along with water before and during exercise but there is currently few data on the contribution to the energy yield of ingested carbohydrate in this situation. In contrast to what is observed in fasted subjects without carbohydrate ingestion during exercise, we have shown that carbohydrate (including exogenous starch) can supply a very large proportion of the energy yield when ingested before and at regular interval during prolonged exercise. Taken together, the results of the experimental studies show that ingested carbohydrates can supply a large fraction of the energy yield during prolonged exercise. However, the exercise mode, the sex and the workload sustained has shown some differences that are mostly due to variations in energy expenditure between experimental conditions or groups of individuals with different characteristics.
