Identification of novel CEBPA double mutations capable of promoting familial AML via the suppression of myeloid differentiation.
Article in American journal of translational research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
CCAAT-enhancer-binding protein α (CEBPA) gene carrying two mutations (CEBPA double mutations) is known to promote familial acute myeloid leukemia (AML). However, the underlying mechanism by which CEBPA double mutations promote AML remains poorly understood. Here we report that a family with three generations suffering from familial AML carries novel double mutations of CEBPA. Seven bases of GCGCGGG were inserted into the N-terminal c.113-114 of CEBPA as germline mutations and three bases of AAG were inserted into the C-terminal c.939-940 as a somatic mutation. To test the functional impact of this double mutation, we constructed plasmid encoding the double mutants of CEBPA and transfected it into the myeloid precursor 32Dcl3 cells. Lentiviral induced overexpression of CEBPA with these double mutations inhibited myeloid differentiation of these 32Dcl3 cells, and led to approximately 4-fold fewer frequency of CD11b expression. Our results confirm that the double mutations of CEBPA at both N- and C-terminals are potentially to induce leukemogenesis of AML.
