Advances on the correlation between hypoxia inducible factor and epigenetic modification / 国际儿科学杂志

ABSTRACT

Hypoxia inducible factor(HIF)is a key factor in the regulation of oxygen homeostasis, and its expression level is mainly influenced by oxygen concentration in the adaptation of the body to chronic hypoxia, with which many pediatric diseases are closely associated.The response to hypoxia can be altered by HIF and its mediated downstream signaling pathways, in addition to epigenetic modifications such as regulation of overall methylation or histone modification levels to adapt to hypoxic environments.Previous studies have shown that the transcriptional activity and stability of HIF are interrelated with various histone modifications including methylation/demethylation, hydroxylation, deacetylation, phosphorylation, and lactylation, which makes the study of epigenetic modification correlation deserves to be explored in depth as an important potential target for regulating HIF expression levels.
