Rapid and sustained degradation of the essential centrosome protein CEP192 in live mice using the AID2 system.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Studying essential genes required for dynamic processes in live mice is challenging as genetic perturbations are irreversible and limited by slow protein depletion kinetics. The auxin-inducible degron (AID) system is a powerful tool for analyzing inducible protein loss in vitro, but it is toxic to mice. Here, we use an optimized second-generation AID system to achieve the conditional and reversible loss of the essential centrosomal protein CEP192 in live mice. We show that the auxin derivative 5-phenyl-indole-3-acetic acid is well tolerated over 2 weeks and drives near-complete CEP192 degradation in less than 1 hour in vivo. CEP192 loss did not affect centriole duplication but decreased γ-tubulin recruitment to centrosomes impairing mitotic spindle assembly. Sustained CEP192 loss in vivo led to cell division failure and cell death in proliferative tissues. Thus, the second-generation AID system is well suited for rapid and/or sustained protein depletion in live mice to study essential functions in vivo.
