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

Differentiation of human pluripotent stem cells (hPSCs) in vitro offers a way to study cell types that are not accessible in living patients. Previous research suggests that hPSCs generate ATP through anaerobic glycolysis, in contrast to mitochondrial oxidative phosphorylation (OXPHOS) in somatic cells; however, specialized cell types have not been assessed. To test if mitobiogenesis is increased during motor neuron differentiation, we differentiated human embryonic stem cell (hESC)- and induced pluripotent stem cell-derived human neural stem cells (hNSCs) into motor neurons. After 21 days of motor neuron differentiation, cells increased mRNA and protein levels of genes expressed by postmitotic spinal motor neurons. Electrophysiological analysis revealed voltage-gated currents characteristic of excitable cells and action potential formation. Quantitative PCR revealed an increase in peroxisome proliferator-activated receptor gamma coactivator 1-α (PGC-1α), an upstream regulator of transcription factors involved in mitobiogenesis, and several of its downstream targets in hESC-derived cultures. This correlated with an increase in protein expression of respiratory subunits, but no increase in protein reflecting mitochondrial mass in either cell type. Respiration analysis revealed a decrease in glycolytic flux in both cell types on day 21 (D21), suggesting a switch from glycolysis to OXPHOS. Collectively, our findings suggest that mitochondrial biogenesis, but not mitochondrial mass, is increased during differentiation of hNSCs into motor neurons. These findings help us to understand human motor neuron mitobiogenesis, a process impaired in amyotrophic lateral sclerosis, a neurodegenerative disease characterized by death of motor neurons in the brain and spinal cord.
