Hypoxia inducible factor-1α as a cancer drug target
1 May 2004
Abstract excerpt
The hypoxia inducible factor 1 (HIF-1) is a heterodimeric transcription factor that is an important regulator of the growing tumor's response to hypoxia. HIF-1 activity in tumors depends on the availability of the HIF-1alpha subunit, the levels of which increase under hypoxic conditions and through the activation of oncogenes and/or inactivation of tumor suppressor genes. HIF-1 activates genes that allow the...
