Mediator‐induced activation of xanthine oxidase in endothelial cells

Friedl, Hans P., Till, Gerd O., Ryan, Una S., Ward, Peter A.·1989·The FASEB Journal

Abstract

Rat pulmonary artery endothelial cells incubated with human serum that has been complement‐activated by addition of cobra venom factor reveal a pronounced conversion of xanthine dehydrogenase to xanthine oxidase. This process requires the availability of the fifth component of complement (C5) but not the presence of other components (C2 and C6‐C9). The phenomenon can be reproduced by addition to endothelial cells of purified human recombinant C5a but not C5a desArg or C3a. The enzyme conversion process is relatively rapid (occurring within 5‐10 min), requires the presence of intact endothelial cells, and does not require protein synthesis. Similar effects on endothelial cells have been obtained with human recombinant tumor necrosis factor a and the chemotactic peptide N‐formyl‐Met‐Leu‐Phe. In contrast, bradykinin, recombinant human interleukin 1β, and phorbol ester lack this biological activity. These findings suggest novel effects of inflammatory mediators on endothelial cells.— F riedl , H. P.; T ill , G. O.; R yan , U. S.; W ard , P. A.

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.
