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

In this report, we describe the development of a transgenic mouse in which a rat probasin promoter (ARR(2)Pb) was used to direct prostate specific expression of a constitutively active form of signal transducer and activator of transcription 3 (i.e., Stat3C). ARR(2)Pb.Stat3C mice exhibited hyperplasia and prostate intraepithelial neoplasia (PIN) lesions in both ventral and dorsolateral prostate lobes at 6 and 12 months; however, no adenocarcinomas were detected. The effect of combined loss of PTEN was examined by crossing ARR(2)Pb.Stat3C mice with PTEN(+/-) null mice. PTEN(+/-) null mice on an ICR genetic background developed only hyperplasia and PIN at 6 and 12 months, respectively. ARR(2)Pb.Stat3C x PTEN(+/-) mice exhibited a more severe prostate phenotype compared with ARR(2)Pb.Stat3C and PTEN(+/-) mice. ARR(2)Pb.Stat3C x PTEN(+/-) mice developed adenocarcinomas in the ventral prostate as early as 6 months (22% incidence) that reached an incidence of 61% by 12 months. Further evaluations indicated that phospho-Stat3, phospho-Akt, phospho-nuclear factor κB, cyclin D1, and Ki67 were upregulated in adenocarcinomas from ARR(2)Pb.Stat3C x PTEN(+/-) mice. In addition, membrane staining for β-catenin and E-cadherin was reduced. The changes in Stat3 and nuclear factor κB phosphorylation correlated most closely with tumor progression. Collectively, these data provide evidence that Stat3 and Akt signaling cooperate in prostate cancer development and progression and that ARR(2)Pb.Stat3C x PTEN(+/-) mice represent a novel mouse model of prostate cancer to study these interactions.
