In Vitro Analysis of Profilin 1 Binding to Recombinant Actin.
Article in Methods in molecular biology (Clifton, N.J.), 2026. 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
Profilin 1 (PFN1) is a key actin-binding protein (ABP) involved in cytoskeletal dynamics, regulating actin polymerization and filament remodeling. While native actin has been extensively studied, recombinant actin produced through biotechnological approaches remains less explored due to solubility and folding challenges. Previously, we assessed the effects of S-nitrosylation on actin binding, providing insights into post-translational modifications that regulate actin function. In the present study, we provide a comprehensive protocol to produce recombinant β-actin using an in vitro transcription-translation system supplemented with chaperonin CCT to analyze its interaction with PFN1. Our findings highlight the utility of recombinant actin for studying ABPs and their regulatory mechanisms, offering a cost-effective alternative for structural and functional analyses.
