Cancer Metastasis

Understanding the relationship between HIF-1 alpha, Hypoxia and Epithelial-Mesenchymal Transition

Epithelial-mesenchymal transition (EMT) is a natural process by which epithelial cells lose their polarity and intercellular adhesion, and gain the migratory invasive properties of mesenchymal stem cells that can differentiate into a variety of cell types. EMT is critical to many developmental processes including embryo development and wound healing. However, EMT is also a fundamental step in the initiation of metastasis during cancer progression.
