Structural Insight Into a Human H Ferritin@Gold-Monocarbene Adduct: Aurophilicity Revealed in a Biological Context.
Article in Angewandte Chemie (International ed. in English), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Human H ferritin (HuHf) has excellent potential as a nanocarrier for the selective delivery of anticancer metal-based drugs to tumor cells. Here, we addressed the interaction of the gold monocarbene compound Au(NHC)Cl with HuHf by electrospray ionization-mass spectrometry (ESI-MS) measurements, which provide the metalation state of the protein subunits and demonstrate the involvement of protein cysteines in gold binding. The adduct between Au(NHC)Cl and HuHf was studied by cryo-EM measurements, resulting in a high-resolution 3D density map at 1.51 Å. The cryo-EM structure shows a novel tetranuclear gold(I) cluster, located in a surface pocket of each subunit where it is bound to Cys90 and Cys102. The short inter-metal distances are diagnostic of the occurrence of aurophilic interactions. The present work demonstrates the usefulness of cryo-EM to investigate the interactions between metal-based drugs and their protein targets/carriers, also leveraging the strong signal of transition metal ions.
