RUNX3

Abstract

RUNX3 is silenced by histone modification and hypoxia-inducible factor (HIF)-1α is stabilized under hypoxia, but little is known of cross-talk between RUNX3 and HIF-1α under hypoxia..
RUNX3 also significantly attenuated the half-life of HIF-1α protein, and induced the cytosolic localization and ubiquitination of HIF-1α. In addition, RUNX3 directly interacted with the C-terminal activation domain of HIF-1α and prolyl hydroxylase (PHD) 2 and enhanced the interaction between HIF-1α and PHD2, which potentiated proline hydroxylation and promoted the degradation of HIF-1α.
