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

Pulmonary neuroepithelial bodies (NEBs) are presumed airway chemoreceptors that express the putative O(2) sensor protein NADPH oxidase and O(2)-sensitive K(+) channels K(+)(O(2)). Although there is a consensus that redox modulation of K(+)(O(2)) may be a common O(2)-sensing mechanism, the identity of the O(2) sensor and related coupling pathways are still controversial. To test whether NADPH oxidase is the O(2) sensor in NEB cells, we performed patch-clamp experiments on intact NEBs identified by neutral red staining in fresh lung slices from wild-type (WT) and oxidase-deficient (OD) mice. In OD mice, cytochrome b(558) and oxidase function was disrupted in the gp91(phox) subunit coding region by insertion of a neomycin phosphotransferase (neo) gene. Expression in NEB cells of neo mRNA, a marker for nonfunctional gp91(phox), was confirmed by nonisotopic in situ hybridization. In WT cells, hypoxia (pO(2) = 15-20 mmHg; 1 mmHg = 133 Pa) caused a reversible inhibition ( approximately 46%) of both Ca(2+)-independent and Ca(2+)-dependent K(+) currents. In contrast, hypoxia had no effect on K(+) current in OD cells, even though both K(+) current components were expressed. Diphenylene iodonium (1 microM), an inhibitor of the oxidase, reduced K(+) current by approximately 30% in WT cells but had no effect in OD cells. Hydrogen peroxide (H(2)O(2); 0.25 mM), a reactive oxygen species generated by functional NADPH oxidase, augmented K(+) current by >30% in both WT and OD cells; further, in WT cells, H(2)O(2) restored K(+) current amplitude in the presence of diphenylene iodonium. We conclude that NADPH oxidase acts as the O(2) sensor in pulmonary airway chemoreceptors.
