Abstract

In addition to controlling a switch to glycolytic metabolism and induction of erythropoiesis and angiogenesis, hypoxia promotes the undifferentiated cell state in various stem and precursor cell populations. Here, we show that the latter process requires Notch signaling. Hypoxia blocks neuronal and myogenic differentiation in a Notch-dependent manner. Hypoxia activates Notch-responsive promoters and increases expression of Notch direct downstream genes. The Notch intracellular domain interacts with HIF-1alpha, a global regulator of oxygen homeostasis, and HIF-1alpha is recruited to Notch-responsive promoters upon Notch activation under hypoxic conditions. Taken together, these data provide molecular insights into how reduced oxygen levels control the cellular differentiation status and demonstrate a role for Notch in this process.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Beyond canonical HRE-driven transcription, HIF isoforms differentially affect signaling pathways by interacting with non-PAS proteins such as p53, c-MYC, β-catenin, and the Notch intracellular domain.

    “Apart from canonical HRE-mediated transcription, the HIF isoforms differentially modulate signaling pathways through interaction with proteins that do not contain PAS domains, such p53, the c-MYC proto-oncogene, β-catenin and the Notch intracellular domain (Fig. 2A) [11–15].”

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.
