Abstract

Haploinsufficiency of Dll4, a vascular-specific Notch ligand, has shown that it is essential for embryonic vascular development and arteriogenesis. Mechanistically, it is unclear how the Dll4-mediated Notch pathway contributes to complex vascular processes that demand meticulous coordination of multiple signalling pathways. Here we show that Dll4-mediated Notch signalling has a unique role in regulating endothelial cell proliferation and differentiation. Neutralizing Dll4 with a Dll4-selective antibody rendered endothelial cells hyperproliferative, and caused defective cell fate specification or differentiation both in vitro and in vivo. In addition, blocking Dll4 inhibited tumour growth in several tumour models. Remarkably, antibodies against Dll4 and antibodies against vascular endothelial growth factor (VEGF) had paradoxically distinct effects on tumour vasculature. Our data also indicate that Dll4-mediated Notch signalling is crucial during active vascularization, but less important for normal vessel maintenance. Furthermore, unlike blocking Notch signalling globally, neutralizing Dll4 had no discernable impact on intestinal goblet cell differentiation, supporting the idea that Dll4-mediated Notch signalling is largely restricted to the vascular compartment. Therefore, targeting Dll4 might represent a broadly efficacious and well-tolerated approach for the treatment of solid tumours.

Claims other papers make about this one

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

  • VEGF acting through VEGFR2 induces endothelial proliferation and concurrently upregulates delta-like ligand 4, which signals to microvascular cells in the capillary stalk to downregulate VEGFR2 via Notch 1, preventing uncontrolled capillary sprouting.

    “Acting through VEGF receptor 2 (VEGFR2), which is localised at high concentrations at the tip of newly formed capillaries, VEGF induces endothelial proliferation,4,47–49 and concur rently upregulates the transmembrane ligand delta-like ligand 4, which signals to microvascular cells in the capillary stalk, to downregulate VEGFR2 via interaction with its receptor Notch 1, thus pre venting uncontroll”
  • Inhibiting Dll4 leads to disruption of tumor vasculature within the TME.

    “For example, Notch ligand Dll4 is upregulated in tumor samples from clear cell renal cell carcinoma patients [135], and inhibiting Dll4 leads to the disruption of tumor vasculature within the TME [136, 137].”

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.
