Abstract

Hypoxia-inducible factors (HIF) are a family of heterodimeric transcriptional regulators that play pivotal roles in the regulation of cellular utilization of oxygen and glucose and are essential transcriptional regulators of angiogenesis in solid tumor and ischemic disorders. The transactivation activity of HIF complexes requires the recruitment of p300/CREB-binding protein (CBP) by HIF-1 alpha and HIF-2 alpha that undergo oxygen-dependent degradation. HIF activation in tumors is caused by several factors including mitogen-activated protein kinase (MAPK) signaling. Here we investigated the molecular basis for HIF activation by MAPK. We show that MAPK is required for the transactivation activity of HIF-1 alpha. Furthermore, inhibition of MAPK disrupts the HIF-p300 interaction and suppresses the transactivation activity of p300. Overexpression of MEK1, an upstream MAPK activator, stimulates the transactivation of both p300 and HIF-1 alpha. Interestingly, the C-terminal transactivation domain of HIF-1 alpha is not a direct substrate of MAPK, and HIF-1 alpha phosphorylation is not required for HIF-CAD/p300 interaction. Taken together, our data suggest that MAPK signaling facilitates HIF activation through p300/CBP.

  • Activated ERK phosphorylates 4E-BP1, S6K, and MNK.

    “Activated ERK phosphorylates 4E-BP1, S6K, and MAP kinase interacting kinase (MNK).”

    From HIF-1α pathway: role, regulation and intervention for cancer therapy (2015) · cites this paper as [39]

    The paper describes ERK1/2 as kinases that phosphorylate nuclear substrates and reports MAPK phosphorylation of p300 in the Discussion (page not provided). Searches for 4E-BP1, S6K, and MNK found no passage identifying them as ERK substrates in our copy. (LLM, conf=0.75)

    From HIF-1α pathway: role, regulation and intervention for cancer therapy (2015) · cites this paper as [39]

    The results section and Discussion describe MAPK phosphorylation of HIF-1α and p300, not MNK phosphorylation of eIF-4E. Searches of our full-text copy for MNK and eIF-4E found no passage addressing the claimed reaction. (LLM, conf=0.76)

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.
