| Research Abstract |
Hypoxia plays a major role in the regulation of many physiological andpathological processes, and is a critical determinant of the pathogenesis of many disorders, including tumor angiogenesis, ischemic heart disease, and stroke. HIF-1 is a master regulater of hypoxia- dependent gene transcription and the active HIF-1 heterodimer binds DNA at conserved hypoxia response elements to activate transcription of target genes. The mechanism of hypoxia-dependent activation of HIF-1 function is not yet understood. We have demonstrated that the mechanism of signal transduction by HIF-1 is a multistep process. Moreover, we have cloned a cDNA for the novel PAS protein which has intrinsic dominant negative function to HIF-1.
