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

Liver receptor homolog-1 (LRH-1, NR5A2) is an orphan nuclear receptor that has an essential role in cancer progression, notably in breast cancer. Although its role in promoting cancer cell proliferation and migration is well documented, the molecular basis is not completely established. Here, we report that LRH-1 inhibition affects two- and three-dimensional cell proliferation of different types of breast cancer cells, including estrogen receptor α (ERα)-positive and triple-negative cells. This phenotype is accompanied by the upregulation of the cyclin-dependent kinase inhibitor CDKN1A (aka p21(CIP1/WAF1)) in a p53-independent manner. Chromatin immunoprecipitation analysis shows that LRH-1 cooperates with FOXA1 and binds directly to CDKN1A promoter and a distal regulatory region found at -62 kb from its transcriptional start sites, allowing repression of CDKN1A transcription. LRH-1 or FOXA1 depletion induces CDKN1A upregulation by removing histone deacetylase 2 from the promoter and distal regulatory elements and permitting histone acetylation in these regions. Analysis of breast cancer samples reveals that a high LRH-1 level is inversely correlated with CDKN1A expression in breast cancer patients and is associated with poor prognosis. This study reveals a novel mechanism of control of cell proliferation by LRH-1 regulating CDKN1A transcription in breast cancer cells, independent of ERα and p53 status. Targeting LRH-1 may provide an attractive prospect for treatment of tumors that are resistant to hormonal and targeted therapy.
