Bisphenol A Induces Sox2 in ER
Article in Hormones & cancer, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
Bisphenol A (BPA) is an endocrine disrupting compound used in food and beverage plastic containers and has been shown to increase breast cancer cellular proliferation. However, the concentrations of BPA used in these experiments are far higher than the physiological levels of BPA detected in the human body. We observed in vitro that exposure of MCF-7 cells to physiological concentrations of BPA failed to increase cell proliferation or to induce canonical estrogen-responsive genes (pS2 and progesterone receptor (PR)), in contrast to 17β-estradiol (E2) treatment. However, MCF-7 cells treated with 10 nM BPA induced ALDH1 expression, a marker of human mammary stem cells. When treated with 10 nM BPA, mammospheres derived either from MCF-7 cells, a patient-derived xenograft, or the normal mouse mammary gland exhibited increased size; however, these effects were not observed in MDA-MB-231 mammospheres. Mechanistically, BPA induced SOX2 mRNA and protein in MCF-7 mammospheres, resulting from enhanced CREB phosphorylation, and subsequent binding of pCREB to a SOX2 downstream enhancer. These findings suggest that physiological levels of BPA increase estrogen receptor-positive breast cancer tumor maintenance through enhanced cancer stem-like cell activity via direct regulation of SOX2 transcription.
