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

A subset of chromosomal translocations in acute leukemias results in the fusion of the trithorax-related protein HRX with a variety of heterologous proteins. In particular, leukemias with the t(11;19)(q23;p13.3) translocation express HRX-ENL fusion proteins and display features which suggest the malignant transformation of myeloid and/or lymphoid progenitor(s). To characterize directly the potential transforming effects of HRX-ENL on primitive hematopoietic precursors, the fusion cDNA was transduced by retroviral gene transfer into cell populations enriched in hematopoietic stem cells. The infected cells had a dramatically enhanced potential to generate myeloid colonies with primitive morphology in vitro. Primary colonies could be replated for at least three generations in vitro and established primitive myelomonocytic cell lines upon transfer into suspension cultures supplemented with interleukin-3 and stem cell factor. Immortalized cells contained structurally intact HRX-ENL proviral DNA and expressed a low-level of HRX-ENL mRNA. In contrast, wild-type ENL or a deletion mutant of HRX-ENL lacking the ENL component did not demonstrate in vitro transforming capabilities. Immortalized cells or enriched primary hematopoietic stem cells transduced with HRX-ENL induced myeloid leukemias in syngeneic and SCID recipients. These studies demonstrate a direct role for HRX-ENL in the immortalization and leukemic transformation of a myeloid progenitor and support a gain-of-function mechanism for HRX-ENL-mediated leukemogenesis.
