UNLABELLED Hypoxia Inducible Factor (HIF), being the master protein involved in adaptation to low pO(2), plays a major role in many physiological and pathological phenomena: development, inflammation, ischemia and cancer. Prolyl hydroxylase (PHD) and factor inhibiting HIF (FIH) are the two oxygen sensors that regulate the HIF pathway. Here we model the(More)
We showed previously that factor-inhibiting hypoxia-inducible factor HIF (FIH) monitors the expression of a spectrum of genes that are dictated by the cell's partial oxygen pressure. This action is mediated by the C-TAD, one of two transactivation domains (TADs) of the hypoxia-inducible factor. Here, we questioned: (1) the function of FIH as a HIF-1(More)
This article is inscribed in the general motivation of understanding the dynamics on biochemical networks including metabolic and genetic interactions. Our approach is continuous modeling by differential equations. We address the problem of the huge size of those systems. We present a mathematical tool for reducing the size of the model, master-slave(More)
