Hypoxia‐inducible factor 1 and cancer pathogenesis
27 May 2008
Abstract excerpt
Hypoxia-inducible factor 1 (HIF-1) is a transcriptional activator that mediates adaptive responses to hypoxia. HIF-1 activity is increased in the majority of human cancers as a result of genetic alterations and intratumoral hypoxia. HIF-1 activates the transcription of genes that increase O(2) availability by stimulating angiogenesis or that reprogram cellular metabolism to adapt to reduced O(2) availability....
