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

We have examined the methylation profiles of the asparagine synthetase (ASY) promoter in a number of human leukemic cell lines in relation to their asparagine (ASN) requirements in vitro. Cells in which the promoter is highly methylated are auxotrophs and express ASY at very low levels. Electromobility shift assays (EMSA) of nuclear extracts with oligomers from the promoting region show, in addition to recognized transcription factor binding, a novel methyl binding protein specific for a 12 base consensus sequence, which includes a single methylated CpG. This sequence overlaps that of the amino-acid response unit of the ASY promoter, which is activated byATF4 and C/EBP. Competition by the methyl binding protein could account for the observed failure of the methylated promoter to bind these transcription factors and consequently, although other mechanisms can also be operative, for the specific repression of the gene. The ASY methyl binding protein (ASMB) is present in leukemic lymphoid and myeloid cells irrespective of their methylation status, and in normal lymphocytes after phytohemagglutinin stimulation. It has been purified by affinity chromatography and has a molecular size of 40 kDa in 10% SDS-polyacrylamide gels.
