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

Lysosomes are essential organelles that regulate cellular homeostasis through complex membrane interactions. Phosphoinositide lipids play critical roles in orchestrating these functions by recruiting specific proteins to organelle membranes. The PIKfyve/Fig4/Vac14 complex regulates PI(3,5)P₂ metabolism, and intriguingly, while loss-of-function mutations cause neurodegeneration, acute PIKfyve inhibition shows therapeutic potential in neurodegenerative disorders. We demonstrate that PIKfyve/Fig4/Vac14 dysfunction triggers a compensatory response where reduced mTORC1 activity leads to ULK1-dependent trafficking of ATG9A and PI4KIIα from the TGN to lysosomes. This increases lysosomal PI(4)P, facilitating cholesterol and phosphatidylserine transport at ER-lysosome contacts to promote membrane repair. Concurrently, elevated lysosomal PI(4)P recruits ORP1L to ER-lysosome-mitochondria three-way contacts, enabling PI(4)P transfer to mitochondria that drives ULK1-dependent fragmentation and increased respiration. These findings reveal a role for PIKfyve/Fig4/Vac14 in coordinating lysosomal repair and mitochondrial homeostasis, offering insights into cellular stress responses.
