[Role of HIF-induced EMT in invasion and
metastasis of tumor].

Hypoxia plays a vital role in tumor metabolism, proliferation, apoptosis, invasion and metastasis via hypoxia-inducible factor (HIF). Epithelial to mesenchymal transition (EMT) is a crucial process to metastasis, which could be triggered by hypoxia. EMT could be regulated by HIF via multiple pathways including TGF-β, Notch, and Wnt/β-catenin. It has been shown that anti-HIF drugs combined with anti-EMT therapies could be a promising strategy for tumor therapy.
