Regulation of glucose responsive protein (GRP) gene expression by insulin.
Article in Cell stress & chaperones, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
While screening for insulin-induced genes, we identified two members of a family of stress-induced genes referred to as glucose-regulated proteins (GRPs). GRPs are members of the stress-responsive superfamily of genes which also includes heat shock proteins (HSPs). The GRP proteins are not normally heat-inducible, but are overproduced when cells are starved of glucose. The two major GRP proteins, GRP78 and GRP94, are highly conserved among vertebrates. We have found that physiological concentrations of insulin stimulate the transcription of GRP78 and GRP94 in rat H4IIE hepatoma cells. The regulation of GRP78 transcription was rapid, with the first induction within minutes, and a further induction after several hours, and both occurred in the presence of glucose. GRP78 transcription was more greatly induced by insulin in the presence of SB202190, a specific p38-MAPK inhibitor. Transcription of GRP94 was also induced, but only after several hours. Calcimycin (A23187) and anisomycin were used to induce endoplasmic reticulum (ER)/cellular stress, and both induced GRP78 and GRP94 transcription.
