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

Worldwide spreading of drug-resistant pathogens makes mechanistic understanding of antibiotic action an urgent task. The macrocyclic antibiotic lipiarmycin (Lpm), which is under development for clinical use, inhibits bacterial RNA polymerase (RNAP) by an unknown mechanism. Using genetic and biochemical approaches, we show that Lpm targets the sigma(70) subunit region 3.2 and the RNAP beta' subunit switch-2 element, which controls the clamping of promoter DNA in the RNAP active-site cleft. Lpm abolishes isomerization of the 'closed'-promoter complex to the transcriptionally competent 'open' complex and blocks sigma(70)-stimulated RNA synthesis on promoter-less DNA templates. Lpm activity decreases when the template DNA strand is stabilized at the active site through the interaction of RNAP with the nascent RNA chain. Template DNA-strand fitting into the RNAP active-site cleft directed by the beta' subunit switch-2 element and the sigma(70) subunit region 3.2 is essential for promoter melting and for de novo initiation of RNA synthesis, and our results suggest that Lpm impedes this process.
