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

The gram negative rod Shigella flexneri uses it surface protein IcsA to induce host cell actin assembly and to achieve intracellular motility. Yet, the IcsA protein lacks the oligoproline sequences found in ActA, the surface protein required for locomotion of the gram positive rod Listeria monocytogenes. Microinjection of a peptide matching the second ActA oligoproline repeat (FEFPPPPTDE) stops Listeria locomotion (Southwick, F.S., and D.L. Purich. 1994a. Proc. Natl. Acad. Sci. USA. 91:5168-5172), and submicromolar concentrations (intracellular concentration 80-800 nM) similarly arrest Shigella rocket-tail assembly and intracellular motility. Coinjection of a binary solution containing profilin and the ActA analogue increased the observed rates of intracellular motility by a factor of three (mean velocity 0.90 +/- 0.07 mu m/s, SD n=16 before injection vs 0.3 +/- 0.1 mu m/s, n=33 postinjection, intracellular concentration = 80 nM profilin plus 80 nM ActA analogue). Recent evidence suggests the ActA analogue may act by displacing the profilin-binding protein VASP (Pistor, S.C., T. Chakaborty, V. Walter, and J. Wehland. 1995. Curr. Biol. 5:517-525). At considerably higher intracellular concentrations (10 muM), the VASP oligoproline sequence (GPPPPP)3 thought to represent the profilin-binding site (Reinhard, M., K. Giehl, K. Abel, C. Haffner, T. Jarchau, V. Hoppe, B.M. Jockusch, and U. Walter. 1995. EMBO (Eur. Mol. Biol. Organ.) J. 14:1583-1589) also inhibited Shigella movement. A binary mixture of the VASP analogue and profilin (each 10 muM intracellular concentration) led to a doubling of Shigella intracellular migration velocity (0.09 +/- 0.06 mu m/s, n = 25 preinjection vs 0.18 +/- 0.10 mu m/s, n = 61 postinjection). Thus, the two structurally divergent bacteria, Listeria and Shigella, have adopted convergent mechanisms involving profilin recognition of VASP oligoproline sequences and VASP recognition of oligoproline sequences in ActA or an ActA-like host protein to induce host cell actin assembly and to provide the force for intracellular locomotion and cell-cell spread.
