Webdependent prolyl-hydroxylases (PHD) and is then degraded through the ubiquitin-proteasome pathway via its interaction with the von Hippel-Lindau (vHL) tumor suppressor protein. In oxygenated cells, hydroxylation of HIF-1a on an asparagine residue prevents interac-tion with the p300 transcriptional co-activator, providing a second Webhypoxia-inducible transcription factors HIF1 and HIF2 regulating cellular responses to hypoxia. Here, we show that the ERα-expressing breast cancer cells MCF-7, CAMA-1, and T47D are less sensitive to antiestrogens when hypoxic. Furthermore, protein and mRNA levels of HIF2α/HIF2A were increased in a panel of antiestrogenresistant
