The signaling pathway of hypoxia inducible factor and its role in renal diseases

Abstract

It is well-documented that hypoxia inducible factor (HIF) is a key mediator of tissue and cellular adaptation to hypoxia. HIF-target genes are also involved in cellular apoptosis and profibrotic mechanisms. The role of HIF in diseases is not consistent. It is a risk factor for tumor progression, whereas it plays a protective role against ischemic hypofusion. For renal diseases, it is not always a risk or protective factor. Many factors are involved in the pathogenesis of renal diseases. It is reported that HIF not only increases hypoxia tolerance, but also regulates a lot of signaling pathways. In the past decades, a number of studies were also conducted to explore the association between HIF and the risk of renal diseases. However, the role of HIF in the development of renal diseases was not entirely clear. In this study, the signal transduction pathways of HIF and its role in the pathogenesis of renal diseases were reviewed.
