Cells 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, whi...
