Energy stress activates AMPK to arrest mitochondria via phosphorylation of TRAK1.
Article in The Journal of cell biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
Neuronal signaling requires large amounts of ATP, making neurons particularly sensitive to defects in energy homeostasis. Mitochondrial movement and energy production are therefore regulated to align local demands with mitochondrial output. Here, we report a pathway that arrests mitochondria in response to decreases in the ATP-to-AMP ratio, an indication that ATP consumption exceeds supply. In neurons and cell lines, low concentrations of the electron transport chain inhibitor antimycin A decrease the production of ATP and concomitantly arrest mitochondrial movement without triggering mitophagy. This arrest is accompanied by the accumulation of actin fibers adjacent to the mitochondria, which serve as an anchor that resists the associated motors. This arrest is mediated by activation of the energy-sensing kinase AMPK, which phosphorylates TRAK1. This mechanism likely helps maintain cellular energy homeostasis by anchoring energy-producing mitochondria in places where they are most needed.
