Dynamic regulation of Gata1 expression during the maturation of conventional dendritic cells.
Article in Experimental hematology, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
objectivesTo identify the regulatory sequences driving Gata1 expression in conventional dendritic cells (cDC). MATERIALS AND
methodsThe number and expression levels of Gata1, Gata1-target genes and hypersensitive site (HS) 2 (the eosinophil-specific enhancer)-driven green fluorescent protein (GFP) reporter of cDCs from mice lacking HS1 (the erythroid/megakaryocytic-specific enhancer, Gata1(low) mutation) and wild-type littermates, as well as the response to lipopolysaccharide of ex vivo-generated wild-type and Gata1(low) DCs were investigated.
resultscDC maturation was associated with bell-shaped changes in Gata1 expression that peaked in cDCs precursors from blood. The Gata1(low) mutation did not affect Gata1 expression in cDC precursors and these cells expressed the HS2-driven reporter, indicating that Gata1 expression is HS2-driven in these cells. By contrast, the Gata1(low) mutation reduced Gata1 expression in mature cDCs and these cells did not express GFP, indicating that mature cDCs express Gata1 driven by HS1. In blood, the number of cDC precursors expressing CD40/CD80 was reduced in Gata1(low) mice, while CD40(pos)/CD80(pos) cDC precursors from wild-type mice expressed the HS2-GFP reporter, suggesting that Gata1 expression in these cells is both HS1- and HS2-driven. In addition, the antigen and accessory molecules presentation process induced by lipopolysaccharide in ex vivo-generated wild-type DC was associated with increased acetylated histone 4 occupancy of HS1, while ex vivo-generated Gata1(low) cDCs failed to respond to lipopolysaccharide, suggesting that HS1 activation is required for cDC maturation.
conclusionThese results identify a dynamic pattern of Gata1 regulation that switches from an HS1 to an HS2-dependent phase during the maturation of cDCs associated with the antigen-presentation process in the blood.
