The dynamic triage interplay of Hsp90 with its chaperone cycle and client binding.
Article in Nature communications, 2024. 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
Hsp90, a crucial molecular chaperone, regulates diverse client proteins, impacting both normal biology and disease. Central to its function is its conformational plasticity, driven by ATPase activity and client interactions. However, comprehensive insights into Hsp90's dynamic molecular transitions remain elusive. Using solution NMR spectroscopy, we reveal how ATP binding, hydrolysis, and client engagement drive conformational and dynamic shifts in E. coli Hsp90, HtpG, through its chaperone cycle. Pronounced conformational fluctuations occur, especially in regions crucial for nucleotide binding and conformational transitions. ATP binding induces slow-exchanging conformations, representing discrete on-path transition states from open to closed forms, while ATP hydrolysis shifts HtpG into a compact conformation. Client binding acts as an allosteric switch, dynamically priming HtpG for elevated chaperone activity and, therefore, its efficient remodeling. Here, we provide atomic-level insights into Hsp90's functional mechanism, highlighting the interplay of conformation, dynamics, nucleotide, and client interactions.
