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

Oestrogen receptor alpha (ERalpha) is an oestrogen-activated transcription factor, which regulates proliferation and differentiation of mammary epithelial cells by activating or repressing gene expression. ERalpha is a critical prognostic indicator and a therapeutic target for breast cancer. Patients with tumours that express higher level of ERalpha have better prognosis than patients with tumours that are ERalpha negative or express lower level of ERalpha. Better prognosis in ERalpha-positive patients is believed to be due to repression of proinvasive gene expression by ERalpha. Oestrogen receptor alpha represses gene expression by transrepressing the activity of the transcription factors such as nuclear factor-kappaB or by inducing the expression of transcriptional suppressors such as MTA3. In this report, we show that ERalpha transrepresses the expression of the proinvasive gene interleukin 6 (IL-6) in ERalpha-negative MDA-MB-231 breast cancer cells stably overexpressing ERalpha. Using these cells as well as ERalpha-positive MCF-7 and ZR-75-1 cells, we show that tumour necrosis factor alpha (TNFalpha) and the phosphatidylinositol-3-kinase (PI3-kinase) modulate transrepression function of ERalpha by reducing its stability. From these results, we propose that TNFalpha expression or PI3-kinase activation lead to reduced levels of ERalpha protein in cancer cells and corresponding loss of transrepression function and acquisition of an invasive phenotype.
