Hypoxia-inducible factors: mediators of cancer progression and targets for cancer therapy

Open access

Abstract

Hypoxia-inducible factors (HIFs) mediate adaptive physiological responses to hypoxia. In human cancers that are accessible for O(2) electrode measurements, intratumoral hypoxia is common and severe hypoxia is associated with increased risk of mortality. HIF activity in regions of intratumoral hypoxia mediates angiogenesis, epithelial-mesenchymal transition, stem-cell maintenance, invasion, metastasis, and resistance to radiation therapy and chemotherapy. A growing number of drugs have been identified that inhibit HIF activity by a variety of molecular mechanisms. Because many of these drugs are already FDA-approved for other indications, clinical trials can (and should) be initiated to test the hypothesis that incorporation of HIF inhibitors into current standard-of-care therapy will increase the survival of cancer patients.

  • Several approaches for targeting hypoxic tumor cells have been proposed including hypoxia-activated prodrugs, gene therapy, recombinant anaerobic bacteria, specific targeting of HIFs, or targeting pathways important in hypoxic cells such as the mTOR and UPR pathways.

    “Several approaches for targeting hypoxic tumor cells have been proposed including hypoxia-activated prodrugs, gene therapy, recombinant anaerobic bacteria, specific targeting of HIFs, or targeting pathways important in hypoxic cells such as the mTOR and UPR pathways (Melillo, 2007;Wilson & Hay, 2011;Semenza, 2012).”

    From Therapeutic targeting of hypoxia and hypoxia-inducible factors in cancer (2016) · cites this paper as Semenza, 2012

    The “HIF-1 inhibitors for cancer therapy” section supports targeting HIFs, and its “HIF-1α synthesis” subsection identifies mTOR inhibitors as one approach (page numbers unavailable). The passages do not support the other listed approaches—hypoxia-activated prodrugs, gene therapy, recombinant anaerobic bacteria, or targeting the UPR pathway—as claims attributable to this source.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
