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

Gene expression of Wnt-1, 2, 3, 4, 5a, 6 and 7a was analyzed by RT-PCR in eleven squamous cell carcinoma (SCC) cell lines and compared with that in two normal oral keratinocyte strains. There appeared to be an inverse relationship between Wnt-4 and Wnt-5a expressions, i.e., Wnt-4 was not expressed in HOC719-NE, HOC313 or TSU cells, while Wnt-5a was strongly expressed only in these cells. These cell lines showed decreased expression of E-cadherin and elevated expression of vimentin accompanied with strong expressions of Snail and deltaEF1, which have been reported to be transrepressors of E-cadherin and to trigger epithelial-mesenchymal transition (EMT), suggesting associations of Wnt-4 with epithelial phenotype and Wnt-5a with mesenchymal phenotype of SCC cells. To study whether the expressions of these Wnt genes are regulated by EMT, we transfected a Snail-expression vector into A431 and OM-1 cells, which express Wnt-4 but not Wnt-5a. The stably Snail-overexpressing clones showed spindle morphology, increased expression of vimentin and decreased expression of E-cadherin accompanied with augmented expression of deltaEF1. In these clones, down-regulation of Wnt-4 and up-regulation of Wnt-5a were clearly observed. These results indicated that Wnt-4 and Wnt-5a are oppositely affected by EMT, and down-regulation of Wnt-4 and up-regulation of Wnt-5a are possible markers of the malignant phenotype of human SCC.
