Full textFirstly, we aimed to establish an ex vivo model of high glucose (HG)-induced endothelial dysfunction in isolated arteries from male Wistar rat and porc. Then, our goal was to clarify the contribution of SGLT1/2 in endothelial cells under HG conditions to evaluate the protective effect of gliflozins on the endothelial function. However, HG did not affect the endothelium-dependent relaxation response in all tested types of artery. The lack of effect of HG might be related to certain factors, such as the incubation conditions, gender, age, strain, species of studied animals, and conditions of housing of animals. Secondly, we characterized human internal mammary arteries (IMA) of 58 patients underwent coronary artery bypass grafting in the New Civil Hospital of Strasbourg. We found the association of diabetes and hypertension in the enhanced level of oxidative stress in human IMA. The expression levels of eNOS, SGLTs and the components of angiotensin system need to be further investigated

Full textThe investigated the role and metabolism of n-3 fatty acids from marine oil (eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids) in bovine aortic endothelial cells. First, we studied the anti-aggregant potential of endothelial cells enriched with EPA or DHA, and their capacity to synthetize prostacyclin. We showed that n-3 fatty acids treated cells were less active than control cells in inhibiting platelet aggregation and in producing prostacyclin, and these phenanena have been positively correlated. In the second part, the metanolic fate of EPA and DHA was studied. He found that they were actively interconverted by endothelial cells, leading to DPA accumulation. In addition, enrichment with n-3 fatty acids modified the cellular concentration of other fatty acids, especially those of the n-6 series. Only EPA altered arachidonic acid concentration in phospholipids. Last, the inhibitory mechanisms displayed by n-3 fatty acids upon the prostacyclin Sjmthesis are analyzed. We observed that prostacyclin formation in n-3 fatty acids enriched cells was similarly inhibited whatever the source of arachidonic acid: endogenous or exogenous. These results suggest that the investigated fatty acids act rather on the enzymic conversion of arachidonic acid than on its avai1ability. We also found a decreased 1eve1 of PGHS-1 and of its transcript in enriched cells, suggesting some transcriptional effects

Full textStroke is a major concern of public health. Etiological treatment is limited to me recanalization of the thrombosed artery (intravenous or intra-arterial thrombolysis by a recombinant of tissue plasminogen activator (rt-PA) and mechanical clot extraction). New neuroprotective drugs are needed to attenuate the deleterious effects of ischemic cascade. High-density lipoproteins (HDLs) are complex molecules having multiple protective activities as reverse cholesterol transport from peripheral tissues back to the liver and the struggle against oxidation, inflammation, apoptosis and thrombosis. These pleiotropic effects confer to HDLs a protective function for vascular endothelium via the interaction with an endothelial receptor, the scavenger receptor class B type 1 (SR-B1). We showed in a murine model of cerebral ischemia that the perfusion of HDL decreased the infarct volume and the blood-brain barrier (BBB) leakage. The neuroprotective effect of HDLs was dependent of their interaction with endothelial SR-B1. The vasculoprotective effect of HDLs on the BBB and the rnle of SR-B1 were confirmed in vitro using a monocellular model of human BBB

Full textMetabolic Syndrome (MS) is associated with an increase in cardiovascular adverse events and specifically with heart failure with preserved ejection fraction (HFpEF). HFpEF represents up to 50% of HF however, no treatment effective on mortality has been yet identified. MS related-HFpEF is a multifactorial syndrome in which an increase in endothelin signaling, in mineralocorticoid receptor activation as well as mitochondria dysfunction is found and participate to the pathology. The present goal of the thesis was to evaluate in three different projects the effects of short- (1 week) and long-term (3 months) treatments, each targeting one of these biological systems, on cardiovascular dysfunction observed in a rat model of MS associated HFpEF. We have chosen the endothelin receptors antagonist macitentan, the mineralocorticoid receptor antagonist finerenone and the new glucose-lowering agent imeglimin. Our results clearly show after the short-term studies an improvement in diastolic dysfunction, an increase in myocardial perfusion as well as restoration of endothelium-dependent coronary relaxation with the 3 treatments. All these improvements were associated with a decrease in left ventricular (LV) reactive oxygen species production (ROS). We obtained the same results after the long-term studies with a decrease in LV interstitial collagen deposition. ROS production was also decreased with the 3 components. This study clearly shows that in a rat model of MS related-HFpEF, blocking endothelin receptors or mineralocorticoid receptors as well as preventing mitochondrial dysfunction is associated with an improvement in cardiac and vascular dysfunctions. These improvements probably involve, among other mechanisms, a decrease in oxidative stress

Full textEPA:DHA 6:1 has been shown to be a superior omega-3 formulation inducing a sustained endothelial NO synthase-derived formation of nitric oxide. This study examined whether chronic intake of EPA:DHA 6:1 prevents hypertension and endothelial dysfunction induced by angiotensin II (Ang II) in rats. Ang II-induced hypertension was associated with endothelial dysfunction characterized by blunted components of relaxation and increased endothelium-dependent contractile responses. Ang II increased the vascular oxidative stress, and the expression of NADPH oxidase subunits, COXs, eNOS, and AT1R whereas SKCa and connexin 37 were down-regulated. Intake of EPA:DHA 6:1 prevented the Ang II-induced hypertension and endothelial dysfunction, and improved expression of target proteins. In conclusion, chronic intake of EPA:DHA 6:1 prevented the Ang II induced hypertension and endothelial dysfunction in rats, most likely by preventing NADPH oxidase and cyclooxygenase-derived oxidative stress

Full textIn utero exposure to maternal metabolic pathologies leads to fetal programming, which increases the occurrence of metabolic, vascular and hepatic diseases in offspring. In this thesis, we focused on fetal programming induced by two types of maternal metabolic dysfunctions : obesity and diabetes. We highlighted that maternal obesity induced direct fetal programming of the vascular function in offspring regardless of metabolic disorders. In addition, we showed that disruption of perinatal nutrition leads to the early occurrence of metabolic disorders in offspring of obese mothers, without modifying the fetal programming of vascular function. Bariatric surgery doesn’t seem tobe able to reverse fetal programming of metabolic and vascular functions as described in obese mothers offspring. We also showed that fetal programming of vascular dysfunction of diabetic mother’s offspring can be transmitted from the F1 to the F2 generation. Finally, we highlighted the importance of sexual dimorphism in the fetal programming of vascular function. These results demonstrate that vascular (arterial hypertension) and metabolic (obesity, diabetes) diseases are not exclusively behavioral diseases but can also have a fetal life origin. They can be transmitted over several generations, thus contributing to explain the worldwide spread of obesity and associated metabolic disorders
