PURPOSE OF REVIEW: Hypoxia inducible factors (HIFs) mediate the transcription of
hundreds of genes that allow cells to adapt to hypoxic environments. In this
review, we summarize the current state of knowledge about mechanisms of HIF
activation in cancer, as well as downstream cancer-promoting consequences such as
altered substrate metabolism, angiogenesis, and cell differentiation. In
addition, we examine the proposed relationship between respiratory-related
hypoxia, HIFs, and cancer. RECENT FINDINGS: HIFs are increased in many forms of
cancer, and portend a poor prognosis and response to therapy. CONCLUSION: HIFs
play a critical role in various stages of carcinogenesis. HIF and its
transcription targets may be useful as biomarkers of disease and therapeutic
targets for cancer.
