1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

NK4, a fragment of hepatocyte growth factor (HGF), exerts bifunctional action as a competitive antagonist against HGF and its receptor c-Met and an angiogenesis inhibitor. Here we studied the anti-angiogenic mechanism of NK4. In cultured human endothelial cells, NK4 inhibited DNA synthesis induced not only by HGF but also by either basic fibroblast growth factor or vascular endothelial growth factor. Even if c-Met expression was diminished by small interference RNA, NK4 inhibited basic fibroblast growth factor-induced DNA synthesis, indicating that anti-angiogenic action of NK4 is c-Met-independent. Affinity purification with NK4-immobilized beads revealed that NK4 binds to perlecan. Consistent with this, NK4 colocalized with perlecan in endothelial cells. Perlecan is a multidomain heparan sulfate proteoglycan that interacts with basement membrane components such as fibronectin. NK4 inhibited extracellular assembly of fibronectin, by which fibronectin-dependent endothelial cell spreading was inhibited by NK4. Knockdown of perlecan expression by small interference RNA significantly abrogated the inhibitory effect of NK4 on fibronectin assembly and cell spreading. In NK4-treated endothelial cells, tyrosine phosphorylation of focal adhesion kinase and Rac activation were reduced, whereas overexpression of activated Rac recovered the DNA synthesis in NK4-treated endothelial cells. These results indicate that the association between NK4 and perlecan impairs fibronectin assembly, thereby inhibiting anchorage-dependent signaling. The identified mechanism for angiostatic action provides further proof of significance for NK4 in the treatment of cancer and potentially for vascular regulation as well.
