MicroRNA-125b-1 accelerates a C-terminal mutant of C/EBPα (C/EBPα-C(m))-induced myeloid leukemia.

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
MicroRNA-125b-1 (miR-125b-1) is a target of the chromosomal translocations t(11;14)(q24;q32) and t(2;11)(p21;q23), which are found in human B-lymphoid and myeloid malignancies, respectively. These translocations result in overexpression of mature miR-125b, consisting of 22 nucleotides. To analyze the role of miR-125b-1 in leukemogenesis, we created a bone marrow transplantation model using a retrovirus vector containing GFP expression elements. Sole transduction of miR-125b-1 into bone marrow cells resulted in expansion of hematopoietic cells expressing GFP. Compared with cells lacking GFP expression, we observed that GFP(+)/CD11b(+) or GFP(+)/Gr(-)1(+) cells were increased in the bone marrow and spleen. Although previous studies reported sole induction of miR-125b-induced leukemia, we did not find leukemic transformation in our model. Transduction of miR-125b-1 did accelerate myeloid tumors induced by a C-terminal mutant of CAAT-enhancer binding protein (C/EBPα-C(m)), a class II-like mutation. As miR-125b has been shown to hasten the development of leukemia in a BCR/ABL-transduced animal model, our present results support the conclusion that overexpression of miR-125b cooperates with other genetic alterations in the pathogenesis of myeloid malignancies.
