Hypoxia-inducible factor 1 (HIF-1) functions as a master regulator of oxygen homeostasis by mediating a wide range of cellular and systemic adaptive physiological responses to reduced oxygen availability. In this review, we will summarize recent progress in elucidating the molecular mechanisms of HIF-1 activation, focusing on the role of oxygen-dependent prolyl and asparaginyl hydroxylases in hypoxia signal transduction. 相似文献

For most of the living beings, oxygen is one of the essential elements required to sustain life. Deprivation of oxygen causes tissue hypoxia and this severely affects host cell and organ functions. Tissue hypoxia is a prominent microenvironmental condition occurring in infections and there is a body of evidence that hypoxia and inflammation are interconnected with each other. The primary key factor mediating the mammalian hypoxic response is hypoxia inducible factor (HIF)-1, which regulates oxygen homeostasis on cellular, tissue and organism level. Recent studies show that HIF-1 plays a central role in angiogenesis, cancer and cardiovascular disease but also in bacterial infections. Activation of HIF-1 depends on the nature of the pathogen and the characteristics of infections in certain hosts. Up to date, it is not completely clear whether the phenomenon of HIF-1 activation in infections has a protective or detrimental effect on the host. In this review, we give an overview of whether and how hypoxia and HIF-1 affect the course of infections. 相似文献
