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

Progesterone (Pg) promotes normal breast development during pregnancy and lactation and increases the risk of developing basal-type invasive breast cancer. However, the mechanism of action of Pg has not been fully understood. In this study, we demonstrate that the mRNA and protein expression of Klf5, a pro-proliferation transcription factor in breast cancer, was dramatically up-regulated in mouse pregnant and lactating mammary glands. Pg, but not estrogen and prolactin, induced the expression of Krüpple-like factor 5 (KLF5) in multiple Pg receptor (PR)-positive breast cancer cell lines. Pg induced the KLF5 transcription through PR in the PR-positive T47D breast cancer cells. Pg-activated PR increased the KLF5 promoter activity likely through binding to a Pg response element at the KLF5 promoter. Importantly, Pg failed to promote T47D cell proliferation when the KLF5 induction was blocked by small interfering RNA. KLF5 is essential for Pg to up-regulate the expression of cell cycle genes, including CyclinA, Cdt1, and E2F3. In addition, KLF5 overexpression was sufficient to induce the cytokeratin 5 (CK5) expression, and the induction of CK5 by Pg was significantly reduced by KLF5 small interfering RNA. Consistently, the expression of KLF5 was positively correlated with that of CK5 in a panel of breast cancer cell lines. Taken together, we conclude that KLF5 is a Pg-induced gene that contributes to Pg-mediated breast epithelial cell proliferation and dedifferentiation.
