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

Acetyl-CoA is a molecule central to cellular metabolic homeostasis. As part of the secretory pathway, acetyl-CoA is imported into the endoplasmic reticulum (ER) by a membrane-bound transporter AT-1 (SLC33A1). AT-1 mutations have been linked to peripheral neuropathy, developmental delay with premature death, and intellectual disability with progeria. Here, we show that AT-1 overexpression impacts diverse phenotypes related to neuronal function and plasticity. Differences in ribosomal, synaptic processing, and metabolic pathways were identified at transcriptomic and proteomic levels. Metabolic adaptations included changes in mitochondrial membrane potential, architecture, and respiration, and tracing experiments revealed changes in the fate of glucose favoring glycogen storage over the pentose phosphate pathway. Altered redox was linked to NAD-dependent proteins SIRT1 and CtBP2. Depletion of lipid stores was associated with greater plasticity in fuel substrate utilization. Metabolic adaptation was coincident with decreased synaptic activity, indicating that neuronal communication is coordinated, in part, through acetyl-CoA metabolism.
