Construction of a Dominant Negative Form of Human Hypoxia-Inducible Factor-2α

摘要

We constructed a dominant negative form of human hypoxia-inducible factor (HIF)-2α, HIF-2αDoN, which inhibited HIF transcriptional activity induced by hypoxia and by HIF-2α. HIF-2αDoN formed a complex with HIF-1β and interacted with DNA containing hypoxia response elements (HREs). Thus, the complex appears to inhibit the binding of HIF-2 to HREs, and HIF-2αDoN might provide a useful therapeutic tool for HIF-2α-related diseases.
