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

Previously, we reported that BRCA1 inhibits progesterone receptor (PR) activity and blocks progesterone-stimulated gene expression and cell proliferation. In the present manuscript, we studied the mechanism of BRCA1 inhibition of PR activity, using c-Myc as a model progesterone-regulated promoter. Here, we found that BRCA1 has little or no effect on PR ligand-binding affinity. However, BRCA1 overexpression inhibited the R5020-induced recruitment of PR to the c-Myc and mouse mammary tumor virus progesterone response elements (PREs) and blocked R5020-stimulated c-Myc expression, whereas BRCA1 underexpression did the opposite. In EMSAs, BRCA1 overexpression blocked the R5020-induced complex formation between PR and several radiolabeled PRE-containing oligonucleotides, and in vitro-translated BRCA1 blocked the interaction of full-length PR-A or a fragment containing the DNA-binding domain of PR with a radiolabeled PRE oligonucleotide. In further studies, BRCA1 overexpression inhibited the recruitment of coactivators (steroid receptor coactivator 1 and amplified in breast cancer 1) and enhanced the recruitment of a corepressor (histone deacetylase 1) to the c-Myc PRE, whereas BRCA1 knockdown increased the abundance of AIB1 and decreased the abundance of HDAC1 at the c-Myc PRE. These findings suggest that BRCA1 inhibits progestin-stimulated PR activity, in part, by preventing PR from binding to the PRE and by promoting the formation of a corepressor complex rather than a coactivator complex.
