Fig. 2From: The role of estrogen receptor beta in breast cancerERβ reduces VEGF transcription via reducing HIF-1α/ARNT complexes. ERβ attenuated the hypoxic induction of VEGF mRNA by directly reducing HIF-1α/ARNT complexes binding to VEGF gene promoter. The inhibition of HIF-1α activity is related to the ability of ERβ to degrade ARNT via ubiquitination processes, leading to the reduction of active HIF-1α/ARNT complexesBack to article page
