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

1. Inhibitors of protein synthesis stimulate sugar transport in mammalian cells through activation of plasma membrane GLUT1, the housekeeping isoform of the glucose transporter. However, it has been reported that some of these compounds, in addition to their effect on protein synthesis, also activate protein kinases. 2. In the present study we have explored the role of these two effects on GLUT1 activation. In 3T3-L1 adipocytes and Clone 9 cells, stimulation of sugar transport by puromycin, a translational inhibitor that does not activate kinases, was not detectable until 90 min after exposure. In contrast, stimulation by anisomycin, a potent Jun-NH2-terminal kinase (JNK) agonist, exhibited no lag phase. An intermediate response was observed to emetine and cycloheximide, weak activators of JNK. 3. The potency of anisomycin to stimulate transport acutely (30 min of exposure) was 5- to 10-fold greater than for its chronic stimulation of transport, measured after 4 h of exposure. The stimulation of transport by a low concentration of anisomycin (0.3 microM) was transient, peaked at 30-60 min and it was inhibited (IC50 < 1 microM) by SB203580, which indicates that its mediator is not JNK, but the homologous p38(MAP kinase) (p38(MAPK)). In contrast, the responses to 4 h exposure to 300 microM anisomycin or puromycin were refractory to SB203580. 4. Exposure to anisomycin resulted in rapid activation of p38(MAPK). Activation of both p38(MAPK) and GLUT1 by 0.3 microM anisomycin was cancelled by puromycin. 5. We conclude that the activation of GLUT1 in response to anisomycin includes two components: a delayed component involving translational inhibition and a fast, puromycin-inhibitable component that is secondary to activation of p38(MAPK).
