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

Bone morphogenetic protein-6 (BMP-6) is a member of the transforming growth factor-beta superfamily. In murine skin, BMP-6 is highly expressed in postmitotic keratinocytes from day 15.5 p.c. till day 6 p.p. Expression in adult skin remains at very low levels, but pathological conditions such as wounding induce the expression of BMP-6. We demonstrate that tumor promotion by TPA (12-O-tetradecanoylphorbol-13-acetate) also induces expression of BMP-6 in suprabasal keratinocytes. This induction is due to post-transcriptional regulation since the level of BMP-6 mRNA remained unchanged. We performed two-stage skin carcinogenesis experiments with transgenic mice epidermally overexpressing BMP-6. These mice display augmented mitotic indices in normal and TPA-treated epidermis when compared to controls. Despite this hyperproliferation, BMP-6 transgenics showed a delayed development and strong suppression of benign and malignant skin tumor formation. In order to resolve this paradox we determined apoptotic frequencies as well as the expression of constituents of AP-1 (activator protein-1) which is essential for tumor promotion. A higher rate of apoptotic keratinocytes was detectable in transgenic mice versus controls and a downregulation of mRNA for jun/fos family members in transgenic skin after TPA-treatment. Thus expression of BMP-6 augments apoptosis and downregulates the transcription of AP-1 family members thereby establishing tumor resistance.
