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 zinc finger E-box binding transcription factor ZEB1 (deltaEF1/Nil-2-a/AREB6/zfhx1a/TCF8/zfhep/BZP) is emerging as an important regulator of the epithelial to mesenchymal transitions (EMT) required for development and cancer metastasis. ZEB1 promotes EMT by repressing genes contributing to the epithelial phenotype while activating those associated with the mesenchymal phenotype. TCF8 (zfhx1a), the gene encoding ZEB1, is induced by several potentially oncogenic ligands including TGF-beta, estrogen, and progesterone. TGF-beta appears to activate EMT, at least in part, by inducing ZEB1. However, our understanding of how ZEB1 contributes to signaling pathways elicited by estrogen and progesterone is quite limited, as is our understanding of its functional roles in normal adult tissues. To begin to address these questions, a human tissue mRNA array analysis was done. In adults, the highest ZEB1 mRNA expression is in bladder and uterus, whereas in the fetus highest expression is in lung, thymus, and heart. To further investigate the regulation of TCF8 by estrogen, ZEB1 mRNA was measured in ten estrogen-responsive cell lines, but it is only induced in the OV266 ovarian carcinoma line. Although high expression of ZEB1 mRNA is estrogen-dependent in normal human ovarian and endometrial biopsies, high expression is estrogen-independent in late stage ovarian and endometrial carcinomas, raising the possibility that deregulated expression promotes cancer progression. In contrast, TCF8 is at least partially deleted in 4 of 5 well-differentiated, grade I endometrial carcinomas, which may contribute to their non-aggressive phenotype. These data support the contention that high ZEB1 encourages gynecologic carcinoma progression.
