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

backgroundAberrations in the regulation of cell proliferation perturb cellular homeostasis and lead to malignancies in which dysregulation of the cell cycle and suppressed apoptosis are 2 common phenomena. Combinatorial nutritional approaches could be efficacious in ameliorating these aberrations.

objectivesWe sought to investigate the effect of dietary broccoli sprouts (BSp) and green tea polyphenol (GTP) administration on cell cycle progression and apoptosis in mammary tumors.

methodsForty female HER2/neu transgenic mice were randomly divided into 4 groups and treated with control, 26% BSp (wt:wt) in food, 0.5% GTPs (wt:vol) in drinking water, or combined BSp and GTPs from dams' conception until their pups were killed at 29 wk of age. Pups' tumor growth was monitored weekly for 27 wk. Tumor cell cycle- and apoptosis-related protein expression was measured. Data were analyzed with 2-factor or 3-factor (repeated-measures) ANOVA.

resultsCompared with the control group, BSp and/or GTPs decreased tumor incidence (P < 0.05) and combined BSp and GTPs synergistically [combination index (CIn) < 1] reduced tumor volume over time (P-time < 0.01). BSp and/or GTPs upregulated the expression of phosphatase and tension homolog, P16, and P53 (P < 0.05) and downregulated myelocytomatosis oncogene, Bmi1 polycomb ring finger oncogene, and telomerase reverse transcriptase (P < 0.05) compared with the control group. Combined BSp and GTPs synergistically (CIn < 1) downregulated the expression of cyclin B1, D1, and E1 and cyclin-dependent kinase 1, 2, and 4 (P < 0.05) compared with the control group. Moreover, combined BSp and GTPs induced apoptosis by regulating Bcl-2-associated X protein and B-cell lymphoma 2 (P < 0.05). BSp and/or GTPs also reduced the expression of DNA methyltransferase 1, 3A, and 3B and histone deacetylase 1 compared with the control group (P < 0.05).

conclusionsCollectively, lifelong BSp and GTP administration can prevent estrogen receptor-negative mammary tumorigenesis through cell cycle arrest and inducing apoptosis in HER2/neu mice.
