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 cytosolic quinone oxidoreductases NQO1 and NQO2 protect cells against oxidative stress by detoxifying quinones and preventing redox cycling. In this study, we used double knockout (DKO) mice deficient for NQO1 and NQO2 to investigate the role of these antioxidative enzymes in a two-stage model of inflammatory skin carcinogenesis. In this model, tumors are caused by exposure to topical carcinogen dimethylbenz(a)anthracene or benzo(a)pyrene (BP) followed by twice weekly application of proinflammatory phorbol 12-myristate 13-acetate. On this classic chemical carcinogenesis protocol, DKO mice showed a significantly higher skin tumor frequency and multiplicity compared with control wild-type or single knockout mice. Analysis of skin from wild-type and DKO mice exposed to BP for 6, 12, or 24 hours revealed a relative delay in the activation of p53, p63, p19ARF, and apoptosis in DKO mice, consistent with a negative modifier role for NQO1/NQO2 in carcinogenesis. Our findings offer genetic evidence of the significance of quinone oxidoreductases NQO1 and NQO2 in limiting chemical skin carcinogenesis.
