Download or read book Diverse Effects of Hypoxia on Tumor Progression written by M. Celeste Simon and published by Springer Science & Business Media. This book was released on 2010-09-28 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hypoxia, defined as reduced oxygen tension, is a common physiological phenomenon in both normal embryonic development and malignancy progression. Although severe hypoxia is generally toxic for both normal tissue and tumors, neoplastic cells gradually adapt to prolonged hypoxia though additional genetic and genomic changes with a net result that hypoxia promotes tumor progression and therapeutic resistance. Hypoxia promotes cancer progression by regulating various aspects of cancer biology, including radiotherapy resistance, metabolism, angiogenesis and invasion/migration
