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

Inactivating mutations in hemojuvelin/repulsive guidance molecule c (HJV/RGMc) cause juvenile hemochromatosis (JH), a rapidly progressive iron overload disorder in which expression of hepcidin, a key liver-derived iron-regulatory hormone, is severely diminished. Several growth factors in the bone morphogenetic protein (BMP) family, including BMP2 and BMP6, can stimulate production of hepcidin, a biological effect that may be modified by RGMc. Here we demonstrate that soluble RGMc proteins are potent BMP inhibitors. We find that 50- and 40-kDa RGMc isoforms, when added to cells as highly purified IgG Fc fusion proteins, are able to block the acute effects of both BMP2 and BMP6 at the levels of Smad induction and gene activation, and thus represent a potentially unique class of broad-spectrum BMP antagonists. Whole transcript microarray analysis revealed that BMP2 and BMP6 each stimulated expression of a nearly identical cohort of approximately 40 mRNAs in Hep3B cells and demonstrated that 40-kDa RGMc was an effective inhibitor of both growth factors, although its potency was less than that of the known BMP2-selective antagonist, Noggin. We additionally show that JH-linked RGMc mutant proteins that retain the ability to bind BMPs are also able to function as BMP inhibitors, and like the wild type soluble RGMc species, can block BMP-activated hepcidin gene expression. The latter results raise the question of whether disease severity in JH will vary depending on the ability of a given mutant RGMc protein to interact with BMPs.
