Abstract

It is now apparent that hypoxia has a central role in the malignant progression of a wide range of solid tumors. For example, hypoxic microenvironments within many human tumors directly affect therapeutic responsiveness and may also contribute to increased survival rates of the more malignant cells following reoxygenation. The detailed nature of these hypoxiadependent resistance phenotypes remains unclear, but it may involve a set of diverse proteins that are induced in response to hypoxic insults. This report reviews the evidence implicating three important hypoxic stress proteins ((p53, heme oxygenase-1, and metallothionein-IIA) in protection against apoptosis, oxidative stress, and antineoplastic drugs following hypoxia/ reoxygenation.
