VPS13B recruits lipid vesicles to promote mitochondrial fission and quality control.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Mutations in the gene VPS13B, which encodes a Golgi-associated protein, cause the neurodevelopmental disorder Cohen syndrome, but the protein's function is unclear. Here we show that this protein is essential for mitochondrial morphology and quality control. Cells lacking VPS13B, including neurons derived from Cohen syndrome patients, exhibit abnormally elongated and fused mitochondria with reduced membrane potential and impaired mitophagy. Mechanistically, the protein localizes to Mitofusin 2-positive mitochondria via its C-terminal region and recruits phosphatidylinositol-4-phosphate-rich Golgi vesicles to mitochondrial fission sites. Loss of VPS13B or depletion of phosphatidylinositol-4-phosphate results in incomplete mitochondrial fission despite normal recruitment of Dynamin-related protein 1, indicating that lipid transfer by VPS13B is required for membrane fission. VPS13B links Golgi-derived lipid vesicles to the mitochondrial fission machinery, ensuring proper mitochondrial fission and quality control and potentially explaining the mitochondrial defects in Cohen syndrome.
