Testo completoCells of solid tumors are often exposed to an environment deficient in oxygen, i.e. hypoxic. The Hypoxia-Inducible Factor-1 (HIF-1) is the major transcription factor involved in cellular adaptation to hypoxia. HIF-1 regulates a wide array of genes involved in angiogenesis, cellular metabolism or pH regulation. My thesis is organized into three axes around HIF-1 and metabolic reprogramming in hypoxia. I first studied Factor-Inhibiting HIF-1 (FIH), one of two oxygen sensors regulating HIF-1. We showed that FIH is essential for tumor development through inhibition of the HIF-1 transcriptional activity as well as through the suppression of the p53-p21 axis. I then studied the HIF-1-induced « shift » in cellular metabolism toward glycolysis, which generates a type of “glucose addiction”. We showed that paradoxically, tumor cells store glycogen in hypoxia through a HIF-1 dependant mechanism. Glycogen served as a reservoir of intracellular glucose, which allows hypoxic cells to survive periods of glucose starvation. Finally, I studied AMPK «the guardian of energy », and showed that surprisingly, this kinase is not necessary in maintaining a viable level of ATP when glycolysis is inhibited (by blockade of lactate export). However, as expected, AMPK protected cells during glucose starvation. Moreover, combined inhibition of the lactate transporter MCT4 and of AMPK reduced dramatically tumor development in a xenograft model, suggesting a crucial role for these two actors in the context of growth of tumor cells in a hostile environment. Taken together these results identified several potential drug targets involved in the metabolic plasticity of hypoxic cells

Testo completoHypoxia refers to a decrease in the oxygen bioavailability at the tissue level. The combination of intermittent hypoxia and hypercapnia is identified in several respiratory diseases as a critical pathophysiological element. However, research suggests that exposure to hypo- or normocapnic hypoxia can improve cardiovascular health. The combination of hypoxic exposure and exercise training has been used by athletes to improve aerobic exercise performance. Recent pilot studies in patients with chronic diseases indicate that exposure to moderate hypoxia at rest or during exercise is likely to induce significant gains in cardiovascular health, body composition and metabolic status.We investigated the effects of normobaric hypoxic exposure on cardiorespiratory and tissue function in healthy subjects, overweight or obese subjects at risk or with cardio-metabolic abnormalities. We assessed the efficacy of 2 types of passive hypoxic conditioning consisting in sustained hypoxia or intermittent hypoxia and hypoxic exercise training in comparison with normoxic condition. First, we assessed the effects of short-term hypoxic exposure at rest in 14 healthy subjects. Then, we evaluated the cardiovascular and metabolic effects of a 8-week normobaric hypoxic conditioning program at rest (intermittent or sustained hypoxia) in 35 overweight or obese patients, compared to placebo normoxic exposure. Next, we conducted a preliminary study in 24 healthy subjects to assess the acute responses to submaximal constant-load and high intensity interval cycling exercise performed in normoxia and in hypoxia. The last study aimed to compare the effect of an 8-week exercise training program performed either in normoxia or hypoxia on maximal aerobic capacity in overweight or obese subjects.In the healthy subject, we emphasized the rapid benefits of intermittent hypoxic conditioning on cardiovascular function (lower baseline systolic blood pressure and increased heart rate variability) and the modulation of tissue deoxygenation in response to hypoxia. We have also shown in healthy subjects that acute exercise (combined with hypoxia causes a similar decrease in muscle oxygenation but a greater prefrontal cortex deoxygenation compared to normoxic condition. Then, in the overweight or obese subject, we have shown that chronic passive hypoxic conditioning induces a decrease in diastolic blood pressure at rest in normoxia, an increase in the hypoxic ventilatory response and a decrease in heart rate variability after intermittent hypoxic conditioning only. In addition, chronic active (exercise training) hypoxic conditioning improves the maximal aerobic capacity compared to placebo normoxic training.Our results show the feasibility of several hypoxic conditioning strategies and their interesting effects on the vascular function in overweight/obese subjects presenting exercise limitations impeding exercise reconditioning. In addition, active hypoxic conditioning showed a greater effect on physical fitness than normoxic exercise training. These hypoxic conditioning strategies must be further optimized to improve their efficacy regarding weight loss and cardiometabolic morbidity in obese. They also represent promising therapeutic opportunities for other chronic diseases

Testo completoLes prolyl-4-hydroxylases (PHD) sont des capteurs d'oxygène qui mesurent les variations de la pression partielle en oxygène dans les cellules. En normoxie elles hydroxylent deux prolines du domaine ODD du facteur transcription hypoxique HIF-1Les prolineshydroxylées fixent la protéine von Hippel Lindau (VHL) et cible HIF-1 vers le protéasome. En hypoxie, les PHD sont inactives : HIF-1 s'accumule, s'associe à HIF-1et induit la transcription des gènes impliqués dans l'adaptation hypoxique. Cette thèse est une contribution à l'analyse des propriétés biochimiques et pharmacologiques des PHD. Nous avons montré que : In vitro : la cyclosporine A, en activant les PHD, inhibe la stabilisation hypoxique de HIF-1, Par ce mécanisme elle réduit la tolérance hypoxique ; l'hypoxie induit l'expression de PHD ; la réoxygénation stimule l'activité des PHD et induit une dégradation rapide de HIF-1. Ce rétrocontrôle négatif de HIF-1 limite les effets de l'hypoxie In vivo chez la drosophile ; la proline 850 du domaine ODD de Similar (l'homologue de HIF-1) est la cible de la PHD ; son hydroxylation permet la fixation de VHL ; la voie de signalisation hypoxique, conservée dans les trachées, présente une spécificité tissulaire. Les PHD jouent un rôle clef dans la stabilisation hypoxique de protéines à domaine ODD et dans l'adaptation hypoxique des cellules. Ce sont des cibles pharmacologiques et thérapeutiques potentielles pour le traitement des pathologies ischémiques
Legendre, Claire. "Adaptation cellulaire et moléculaire des cellules d'hépatome humain HepaRG à un environnement hypoxique". Rennes 1, 2009. http://www.theses.fr/2009REN1S055.
Testo completoReduced oxygen level, or hypoxia, is frequently encountered in solid tumours and contributes to drug resistance. Hypoxia is also associated with invasive phenotype and correlated to poor prognosis and mortality. The role of hypoxia in hepatocellular carcinoma biology is not fully understood. Therefore, there is a need for developing in vitro models mimicking hypoxic conditions find within solid tumours using hepatic tumour cells. Highly differentiated human hepatoma HepaRG cells respond to hypoxia by a switch from aerobic to anaerobic glycolysis. Moreover, we showed that hypoxia also repressed drug-metabolizing enzymes expression. These repressions could therefore strongly compromise chemotherapy effectiveness on tumour cells within hypoxic environment. Furthermore, HepaRG cells cultured under hypoxic versus normoxic conditions might represent a new strategy to test different types of therapeutic molecules in order to predict their effectiveness
