Abstract

Endothelial cell growth factor (ECGF) is a potent polypeptide mitogen for endothelial cells and fibroblasts. The mitogenic effects of ECGF are inhibited by the lymphokine gamma-interferon (gamma-IFN) in a dose-dependent manner. Gamma-IFN also induces a unique change in endothelial cell morphology which is maximally expressed in the presence of ECGF. The antiproliferative and phenotypic modulatory effects of gamma-IFN on endothelial cells are reversible. Inhibition of ECGF-induced endothelial cell proliferation by gamma-IFN is accompanied by a concentration- and time-dependent decrease in binding of 125I-ECGF to the endothelial cell surface. Scatchard analyses of the binding data in the presence and absence of gamma-IFN demonstrate a decrease in the number of ECGF-binding sites rather than a decrease in ligand affinity for the receptor. Cross-linking experiments with disuccinimidyl suberate demonstrate a decrease in the 170,000 Mr cross-linked receptor-ligand complex. These data suggest that gamma-IFN inhibits endothelial cell proliferation by a mechanism which involves growth factor receptor modulation.

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.
