Angiopoietin-Related/Angiopoietin-Like Proteins Regulate Angiogenesis

Abstract

A general understanding of the molecular mechanisms underlying angiogenesis is emerging from the analysis of targeted mutations in vasculature-related genes. These analyses reveal that angiopoietin signaling through the TIE2 receptor is involved in regulating angiogenesis. Recently, we and several other groups have independently identified several molecules containing a coiled-coil domain and a fibrinogen-like domain, both of which are structurally conserved in angiopoietins. Because these molecules do not bind to the angiopoietin-specific receptor,TIE2, they have been named angiopoietin-related proteins (ARPs) or angiopoietin-like proteins (Angptls). ARPs/Angptls, which are all currently orphan ligands, also have potent activity for regulating angiogenesis as proangiogenic or antiangiogenic factors, suggesting that their receptors may be expressed on endothelial cells. In addition, ARPs/Angptls show pleiotropic effects not only on vascular cells but also on cells of other lineages, such as skin and chondrocyte cells. More recent studies have proposed that ARPs/Angptls are involved in various pathologies, such as tumor angiogenesis and metabolic diseases. To summarize the current findings relating to these proteins, we focus in this review on the functions of ARPs/Angptls as new angiogenic modulating factors in the vascular system and discuss the pleiotropic functions of ARPs/Angptls in nonvascular cell lineages.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • The XENO clusters within the xenograft tissue may be hypoxic because of a lack of vasculature and the wound healing process from the xenograft technique.

    “suggesting that the XENO clusters within the xenograft tissue may be hypoxic because of a lack of vasculature and the wound healing process from the xenograft technique.”
  • THBS and ANGPTL signaling are known to promote angiogenesis.

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.
