Epigenetic re-expression of HIF-2α suppresses soft tissue sarcoma growth

Abstract

Hypoxia is a common feature of soft tissue sarcomas, resulting in the activation of HIF-1α, which promotes metastasis. Here, Nakazawa et al. show that paradoxically HIF-2α is epigenetically silenced during the progression of multiple sarcoma subtypes, and when reexpressed, blocks tumour growth in vivo.
