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

Neurexin I α (NRXN1α) and Dystroglycan (DAG1) are membrane receptors which serve as mutual ligands in the neuronal system. Neurexophilins (NXPHs) bind NRXN1α. NRXN1α was expressed in primitive populations in human CB (huCB) and murine BM (muBM). DAG1 is ubiquitously expressed in hematopoietic tissue; however, osteoblasts appear to be sites of very high expression within muBM. High concentrations of NXPH were found in huCB plasma and murine lineage-positive splenocytes. We evaluated effects of these molecules on huCB and muBM hematopoietic progenitor cells (HPCs) and HSCs. At both a single and population cell level in vitro, we found that NXPH1 was a potent inhibitor of HPC proliferation acting through NRXN1α an effect down-modulated by DAG1. Injection of recombinant NXPH1 in vivo resulted in myelo- and lymphosuppression in the BM, with absolute numbers and cycling status of functional and phenotypically defined HPCs dose- and time-dependently decreased. Competitive HSC transplantations showed no change in the long-term repopulating activity of HSCs from mice exposed to recombinant NXPH1. These results demonstrate the presence and function of a regulated signaling axis in hematopoiesis centered on NRXN1α and its modulation by DAG1 and NXPH1.
