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

Poly(ADP-ribose) polymerase-1 (Parp-1) is activated by DNA strand breaks and functions in the maintenance of genomic integrity and cell death control. On the other hand, Parp-1 is also involved in transcriptional regulation of various genes, and the relationship between Parp-1 deficiency and susceptibility to tumorigenesis has not been fully elucidated. In the present study, Parp-1(-/-) mice, harboring exon 1 disruption in Parp-1, and Parp-1(+/+) animals were administered azoxymethane (AOM) at a dose of 10 mg/kg body weight once a week for 6 weeks. At 30 weeks after the first carcinogen treatment, mice were sacrificed. The incidence of animals bearing either adenomas or adenocarcinomas in the colon and the average number of colon tumors per mouse were significantly higher in Parp-1(-/-) mice than in Parp-1(+/+) animals. beta-Catenin accumulation was observed in 43/44 of Parp-1 (-/-) tumors and 19/21 of the Parp-1(+/+) tumors and was not statistically different between the genotypes. This suggests that most tumors developed through a pathway involving the alteration of Wnt-beta-catenin signaling in both Parp-1(-/-) and Parp-1(+/+) mice. In the liver, where AOM is primarily activated, the incidence of animals bearing nodules and the average number of nodules per section were significantly increased in Parp-1(-/-) mice compared with Parp-1(+/+) mice. Therefore, the results indicate that susceptibility to AOM-induced tumorigenesis in the colon and also in the liver is enhanced in Parp-1(-/-) mice, and Parp-1 could have a substantial role in colon and liver tumorigenesis.
