PILS-Nir1 is a sensitive phosphatidic acid biosensor that reveals mechanisms of lipid production.
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 8 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
Phosphatidic acid (PA) regulates lipid homeostasis and vesicular trafficking, yet high-affinity tools to study PA in live cells are lacking. We identified the lipin-like sequence of Nir1 (PILS-Nir1) as a candidate PA biosensor based on structural analysis of Nir1's LNS2 domain. Using liposome-binding assays and pharmacological and genetic manipulations in HEK293A cells expressing fluorescent PILS-Nir1, we found that while PILS-Nir1 binds PA and PIP2in vitro, only PA is necessary and sufficient for membrane localization in cells. PILS-Nir1 displayed greater sensitivity to organelle-generated PA than Spo20-based probes, enabling visualization of modest PA production by PLD downstream of muscarinic receptors-previously undetectable with existing biosensors. Thus, PILS-Nir1 provides a versatile, sensitive tool for real-time PA dynamics in live cells.
