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

ELL-associated factor 1 is a transcription elongation factor that shares significant homology and functional similarity to the androgen-responsive prostate tumor suppressor ELL-associated factor 2. EAF2 is frequently down-regulated in advanced prostate cancer and Eaf2 deletion in the mouse induced the development of murine prostatic intraepithelial neoplasia. Here we show that similar to EAF2, EAF1 is frequently down-regulated in advanced prostate cancer. Co-downregulation of EAF1 and EAF2 occurred in 40% of clinical specimens with Gleason score >7. We developed and characterized a murine model of prostate-epithelial specific deletion of Eaf1 in the prostate and crossed it with our previously generated mouse with conventional deletion of Eaf2. The prostates of Eaf1 deletion mice displayed murine prostatic intraepithelial neoplasia lesions with increased proliferation and inflammation. Combined deletion of Eaf1 and Eaf2 in the murine model induced an increased incidence in mPIN lesions characterized by increased proliferation and CD3+ T cells and CD19+ B cells infiltration compared to individual deletion of either Eaf1 or Eaf2 in the murine prostate. These results suggest that EAF1 may play a tumor suppressive role in the prostate. Cooperation between EAF1 and EAF2 may be important for prostate maintaining prostate epithelial homeostasis, and concurrent loss of these two tumor suppressors may promote prostate tumorigenesis and progression.
