(HIF-1 ?) and its Role in Tumour Progression to Malignancy %X Hypoxia is a condition in which an area of the body or a tissue is deprived of sufficient supply of oxygen. The lack of nutrients in a hypoxic tissue generally causes apoptosis but some cells are able to adapt to this hypoxic environment and resist apoptosis. This adaptation occurs as a result of gene activation. Hypoxia is a characteristic feature of many cancers and is the stimulus for overexpression of HIF-1? - a basic loop-helix PAS protein family subunit of HIF, which allows the cell to adapt and survive in hostile environment. The presence of hypoxia and HIF-1? is correlated with an increased risk of metastasis and techniques that can inhibit hypoxia inducible factor may be instrumental in finding a cure for cancer %N 2 %K HIF, HIF-1?, Hypoxia, Malignancy, Cancer, Cancer Therapy %E Dr. Srinivas Kakkilaya %V 7 %D 2008 %I Dr. B.S.
