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

Multiple sclerosis (MS) is characterized by demyelination and progressive neurological disability. Previous studies have reported defects to mitochondria in MS including decreased expression of nuclear encoded electron transport chain subunit genes and inhibition of respiratory complexes. We previously reported increased levels of the hemoglobin β subunit (Hbb) in mitochondrial fractions isolated from postmortem MS cortex compared to controls. In the present study, we performed immunohistochemistry to determine the distribution of Hbb in postmortem MS cortex and identified proteins which interact with Hbb by liquid chromatography tandem mass spectrometry (LC-MS/MS). We found that Hbb was enriched in pyramidal neurons in internal layers of the cortex and interacts with subunits of ATP synthase, histones, and a histone lysine demethylase. We also found that Hbb is present in the nucleus and that expression of Hbb in SH-SY5Y neuroblastoma cells increased trimethylation of histone H3 on lysine 4 (H3K4me3), a histone mark that regulates cellular metabolism. These data suggest that Hbb may be a part of a mechanism linking neuronal energetics with epigenetic changes to histones in the nucleus and may provide neuroprotection in MS by supporting neuronal metabolism.
