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

Nicotinic acetylcholine receptor (nAChR) genes form a highly conserved gene cluster at the lung cancer susceptibility locus 15q25.1. In this study, we show that the CHRNalpha3 gene encoding the nAChRalpha3 subunit is a frequent target of aberrant DNA hypermethylation and silencing in lung cancer, whereas the adjacent CHRNbeta4 and CHRNalpha5 genes exhibit moderate and no methylation, respectively. Treatment of cancer cells exhibiting CHRNalpha3 hypermethylation with DNA methylation inhibitors caused demethylation of the CHRNalpha3 promoter and gene reactivation. Restoring CHRNalpha3 levels through ectopic expression induced apoptotic cell death. Small hairpin RNA-mediated depletion of nAChRalpha3 in CHRNalpha3-expressing lung cancer cells elicited a dramatic Ca(2+) influx response in the presence of nicotine, followed by activation of the Akt survival pathway. CHRNalpha3-depleted cells were resistant to apoptosis-inducing agents, underscoring the importance of epigenetic silencing of the CHRNalpha3 gene in human cancer. In defining a mechanism of epigenetic control of nAChR expression in nonneuronal tissues, our findings offer a functional link between susceptibility locus 15q25.1 and lung cancer, and suggest nAChRs to be theranostic targets for cancer detection and chemoprevention.
