An advanced toolset to manipulate and monitor subcellular phosphatidylinositol 3,5-bisphosphate.
Article in The Journal of cell biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Phosphatidylinositol (PI) 3,5-bisphosphate (PI(3,5)P2) is a minor inositol-containing phospholipid that serves as an important regulator of endolysosomal functions. However, the precise sites of subcellular enrichment and molecular targets of this regulatory lipid are poorly understood. Here, we describe the generation and detailed characterization of a short engineered catalytic fragment of the human PIKfyve enzyme, which potently converts PI 3-phosphate to PI(3,5)P2. This novel tool allowed for the evaluation of reported PI(3,5)P2-sensitive biosensors and showed that the recently identified phox homology (PX) domain of the Dictyostelium discoideum (Dd) protein, SNXA, can be used to monitor the production of PI(3,5)P2 in live cells. Modification and adaptation of the DdSNXAPX-based probes into compartment-specific bioluminescence resonance energy transfer-based biosensors allows for the real-time monitoring of PI(3,5)P2 generation within the endocytic compartments of entire cell populations. Collectively, these molecular tools should allow for exciting new studies to better understand the cellular processes controlled by localized PI(3,5)P2 metabolism.
