The MEK Inhibitor, PD98059 Blocks the Transactivation, but not the Stabilization or DNA Binding Ability, of Hypoxia-Inducible Factor-1$\alpha$

Abstract

Under low oxygen tension, cells increase the transcription of specific genes that are involved in angiogenesis, erythropoiesis and glycolysis. Hypoxia-induced gene expression primarily depends on the stabilization of the subunit of Hypoxia-Inducible Factor-1 (HIF-1), which acts as a heterodimeric transactivator.(omitted)
