Hypoxia‐inducible factor‐1α in non small cell lung cancer: Relation to growth factor, protease and apoptosis pathways

Hypoxia-inducible factor (HIF)-1 alpha is the regulatory subunit of HIF-1 that is stabilized under hypoxic conditions. Under different circumstances, HIF-1 alpha may promote both tumorigenesis and apoptosis. There is conflicting data on the importance of HIF-1 alpha as a prognostic factor. This study evaluated HIF-1 alpha expression in 172 consecutive patients with stage I-IIIA non small cell lung cancer (NSCLC) using standard …
