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

The Ras-mitogen activated protein kinase (Ras-MAPK) pathway plays an integral role in the formation of human malignancies. Stimulation of this pathway results in phosphorylation of histone H3 at serines 10 and 28 and expression of immediate-early genes. Phosphorylated (serine 10) H3, which is also acetylated on lysine 14, is associated with immediate-early genes. In this report, we investigated the relationship between these two H3 phosphorylation events in parental and ras-transformed fibroblasts. Immunoblot analyses of two-dimensional gel patterns demonstrated that all three H3 variants were phosphorylated after stimulation of the Ras-MAPK pathway and during mitosis. Following stimulation of the Ras-MAPK pathway, H3 phosphorylated on serines 10 and 28 was excluded from regions of highly condensed chromatin and was present in increased levels in ras-transformed cells. Although H3 phosphorylated at serine 10 or 28 was dynamically acetylated, H3 phosphorylated at serine 28 had a higher steady state of acetylation than that of H3 phosphorylated at serine 10. When visualized with indirect immunofluorescence, most foci of phosphorylated serine 28 H3 did not co-localize with foci of H3 phosphorylated on serine 10 or phosphoacetylated on serine 10 and lysine 14, suggesting that these two phosphorylation events act separately to promote gene expression.
