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

Glycogen synthase kinase (GSK)3beta is a ser-thr kinase that is phosphorylated by the kinase Akt. Although Akt has been shown to regulate platelet function and arterial thrombosis, its effectors in platelets remain unknown. We show here that agonist-dependent phosphorylation of GSK3beta in platelets is Akt dependent. To determine whether GSK3beta regulates platelet function, platelets from mice lacking a single allele of GSK3beta were compared with those of wild-type (WT) controls. GSK3beta+/- platelets demonstrated enhanced agonist-dependent aggregation, dense granule secretion, and fibrinogen binding, compared with WT platelets. Treatment of human platelets with GSK3 inhibitors renders them more sensitive to agonist-induced aggregation, suggesting that GSK3 suppresses platelet function in vitro. Finally, the effect of GSK3beta on platelet function in vivo was evaluated using 2 thrombosis models in mice. In the first, 80% of GSK3beta+/- mice (n=10) formed stable occlusive thrombi after ferric chloride carotid artery injury, whereas the majority of wild-type mice (67%) formed no thrombi (n=15). In a disseminated thrombosis model, deletion of a single allele of GSK3beta in mice conferred enhanced sensitivity to thrombotic insult. Taken together, these results suggest that GSK3beta acts as a negative regulator of platelet function in vitro and in vivo.
