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

background and purposeSoluble guanylate cyclase (sGC) is the signal transduction enzyme most responsible for mediating the effects of nitric oxide (NO). Recently, NO-independent small molecule activators of sGC have been developed that have promising clinical activities. We have shown that the secreted matrix protein thrombospondin-1 (TSP-1) binds to CD47 and potently inhibits NO stimulation of sGC in endothelial and vascular smooth muscle cells (VSMCs) and platelets. Here we show that TSP-1 signalling via CD47 inhibits sGC activation by NO-independent sGC activating small molecules. EXPERIMENTAL APPROACH: Vascular smooth muscle cells and washed human platelets were pretreated with TSP-1 (2.2 nM) in the presence of haeme-dependent sGC activators (YC-1, BAY 41-2272), and a haeme-independent activator (meso-porphyrin IX), and cGMP levels were measured. The effect of sGC activators on platelet aggregation and contraction of VSMC embedded in collagen gels was also assayed in the presence and absence of TSP-1. KEY

resultsThrombospondin-1 inhibited sGC activator-dependent increase in cGMP in VSMC and platelets. TSP-1 pretreatment also inhibited the ability of these agents to delay thrombin-induced platelet aggregation. TSP-1 pretreatment reduced the ability of sGC activating agents to abrogate VSMC contraction in vitro. CONCLUSIONS AND IMPLICATIONS: This work demonstrates that TSP-1 is a universal inhibitor of sGC, blocking both haeme-dependent and haeme-independent activation. These data coupled with the reported increases in TSP-1 with age, diabetes, ischaemia/reperfusion, and atherosclerosis implies that the therapeutic potential of all drugs that activate sGC could be compromised in disease states where TSP-1/CD47 signalling is elevated.
