Abstract

Hypoxia inducible factors (HIFs) are transcription factors, which are commonly expressed in mammals, including humans. The HIFs consist of hypoxia-regulated α and oxygen‑insensitive β subunits, and are key regulators of gene expression during hypoxia in normal and solid tumor tissues. Three members of the HIF family, HIF‑1α, HIF‑2α, and HIF‑3α, are currently known. HIF‑3α differs from HIF‑1α and HIF‑2α in protein structure and regulation of gene expression. For a long time, HIF‑3α was considered as a negative mediator of HIF‑regulated genes. HIF‑3 has a transcriptional regulatory function, which negatively affects gene expression by competing with HIF‑1α and HIF‑2α in binding to transcriptional elements in target genes during hypoxia. Previously, certain target genes of HIF‑3α have been identified, confirming the role of HIF‑3α as a transcription factor. In this review, the protein structure, gene regulation and biological function of HIF-3 are discussed based on the literature.
