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

C57BL/6N (N) and C57BL/6J (J) mice possess key genetic differences, including a deletion in the Nicotinamide nucleotide transhydrogenase (Nnt) gene that results in a non-functional protein in J mice. NNT regulates mitochondrial oxidative stress. Although elevated oxidative stress can compromise hematopoietic stem and progenitor cell (HSPC) function, it is unknown whether N- and J-HSPCs are functionally equivalent. Here, we report that J-HSPCs display compromised short-term hematopoietic repopulating activity relative to N-HSPCs that is defined by a delay in lymphoid reconstitution and impaired function of specific multi-potent progenitor populations post transplant. J-HSPCs also displayed elevated reactive oxygen species (ROS) relative to N-HSPCs post transplant and upregulate ROS levels more in response to hematopoietic stress. Nnt knockdown in N-HSPCs recapitulated J-HSPCs' short-term repopulating defect, indicating that NNT loss contributes to this defect. In summary, C57BL/6N and C57BL/6J HSPCs are not functionally equivalent, which should be considered when determining the substrain most appropriate for investigations of HSPC biology.
