Hypoxia, Clonal Selection, and the Role of HIF-1 in Tumor Progression
1 Jan 2000
Abstract excerpt
Tumor progression occurs as a result of the clonal selection of cells in which somatic mutations have activated oncogenes or inactivated tumor suppressor genes leading to increased proliferation and/or survival within the hypoxic tumor microenvironment. Hypoxia-inducible factor 1 (HIF-1) is a transcription factor that mediates adaptive responses to reduced O2 availability, including angiogenesis and glycolysis....
