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

Voltage changes across the cell membrane control the gating of many cation-selective ion channels. Conserved from bacteria to humans, the voltage-gated-ligand superfamily of ion channels are encoded as polypeptide chains of six transmembrane-spanning segments (S1-S6). S1-S4 functions as a self-contained voltage-sensing domain (VSD), in essence a positively charged lever that moves in response to voltage changes. The VSD 'ligand' transmits force via a linker to the S5-S6 pore domain 'receptor', thereby opening or closing the channel. The ascidian VSD protein Ci-VSP gates a phosphatase activity rather than a channel pore, indicating that VSDs function independently of ion channels. Here we describe a mammalian VSD protein (H(V)1) that lacks a discernible pore domain but is sufficient for expression of a voltage-sensitive proton-selective ion channel activity. H(v)1 currents are activated at depolarizing voltages, sensitive to the transmembrane pH gradient, H+-selective, and Zn2+-sensitive. Mutagenesis of H(v)1 identified three arginine residues in S4 that regulate channel gating and two histidine residues that are required for extracellular inhibition of H(v)1 by Zn2+. H(v)1 is expressed in immune tissues and manifests the characteristic properties of native proton conductances (G(vH+)). In phagocytic leukocytes, G(vH+) are required to support the oxidative burst that underlies microbial killing by the innate immune system. The data presented here identify H(v)1 as a long-sought voltage-gated H+ channel and establish H(v)1 as the founding member of a family of mammalian VSD proteins.
