In Vivo Optogenetic Phase Transition of an Intrinsically Disordered Protein.
Article in Methods in molecular biology (Clifton, N.J.), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Proteins containing intrinsically disordered regions (IDRs) control a wide variety of cellular processes by assembly of membrane-less organelles via IDR-mediated liquid-liquid phase separation. Dysregulated IDR-mediated phase transition has been implicated in the pathogenesis of diseases characterized by deposition of abnormal protein aggregates. Here, we describe a method to enhance interactions between the IDRs of the RNA/DNA-binding protein and TAR DNA-binding protein 43 (TDP-43) by light to drive its phase transition in the motor neurons of zebrafish. The optically controlled TDP-43 phase transition in motor neurons, in vivo, provides a unique opportunity to evaluate the impact of dysregulated TDP-43 phase transition on the physiology of motor neurons. This will help to address the etiology of neurodegenerative diseases associated with abnormal TDP-43 phase transition and aggregation, including amyotrophic lateral sclerosis (ALS).
