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

Normal mammary epithelial cells are rapidly induced to G(1) arrest by the widely expressed cytokine, transforming growth factor beta (TGF-beta1). Studies in established breast cancer cell lines that express the estrogen receptor alpha (ERalpha) have demonstrated loss of this responsiveness. This inverse correlation suggests interpathway signaling important to cell growth and regulation. The adenocarcinoma breast cell line BT474, which was not growth arrested by TGF-beta1, was used as a model of estrogen-inducible growth to explore interpathway crosstalk. Although BT474 cells were not growth-arrested by TGF-beta1 as determined by flow cytometry analysis and 5'-bromo-3'-deoxyuridine incorporation into DNA, estrogen receptor protein levels were attenuated by 100 pM TGF-beta1 after 6 h. This decrease in ERalpha reached 50% of untreated control levels by 24 h of treatment and was further supported by a 50% decrease in estrogen-inducible DNA synthesis. Inspection of ERalpha transcripts suggested that this decrease was primarily the result of altered ERalpha protein stability or availability. Use of the proteasome inhibitor, MG132, abolished all effects on ERalpha by TGF-beta1. Collectively, this data supports a role for TGF-beta1 in regulating the growth of otherwise insensitive breast cancer cells through modulation of ERalpha stability.
