Localization and characterization of ST7 in cancer.
Article in Journal of cancer research and clinical oncology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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.
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
purposeST7 has been proposed to be a tumor suppressor gene in the chromosome region 7q31.1-q31.2. In order to gain some insight into its role in cancer, the localization and verification of the ST7 expression levels were determined.
methodsVarious types of ST7 expression vectors tagged with the sequences of GFP, YFP or V5 were created using a gateway cloning system and full-length ST7 cDNA isolated from a human adult brain cDNA library. Cell cycle synchronization was also performed to analyze the expression of endogenous ST7 and its potentially related genes at each stage of the cell cycle.
resultsCytosolic ST7 expression in HCT-116, MCF-7 and PC-3 cancer cell lines was detected via the fluorescence signal of the fusion proteins. ST7 translocation from the cytoplasm to the nucleus has not been observed in any of the conditions assayed. A cell cycle synchronization study demonstrated that both ST7 and SERPINE1 were overexpressed when cells were arrested. Expression of these genes was found to be diminished when the cells re-entered cell division status. In addition, we also found that Survivin, MMP-13 and Cyclin D1 were differentially expressed during the cell cycle.
conclusionOur findings suggest that ST7 mediates tumor suppression through the regulation of the genes involved in maintaining the cellular structure of the cell and involved in oncogenic pathways.
