HIF‐1 is expressed in normoxic tissue and displays an organ‐specific regulation under systemic hypoxia

Adaptation to hypoxia is regulated by hypoxia-inducible factor 1 (HIF-1), a heterodimeric transcription factor consisting of an oxygen-regulated alpha subunit and a constitutively expressed beta subunit. Although HIF-1 is regulated mainly by oxygen tension through the oxygen-dependent degradation of... View More
