Interactome Profiling of a Lysine Deacetylase Trapping Probe Library Uncovers Crosstalk Between HDAC6 and NF-κB Signaling.
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 1 paper.
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
Lysine or histone deacetylases (HDACs) remove acetyl groups from lysine residues of numerous proteins, thereby regulating their function and activity. HDAC6 is involved in multiple cellular processes, yet its protein interaction network remains poorly understood. To uncover novel HDAC6 substrates, we performed an acetylome analysis of HDAC6 knockdown cells, which served as a basis for the design of an HDAC6-trapping peptide library containing hydroxamic acids. Most probes enriched HDAC6 from cell lysates stronger than HDAC1. Proteomic profiling of the trapping probes revealed a preferential enrichment of HDAC6 and resulted in the identification of novel putative HDAC6 interaction partners. Among those were several components of the pro-inflammatory transcription factor NF-κB that were independently confirmed as HDAC6 binders. Mechanistically, HDAC6 counteracted NF-κB activity induced upon p300-catalyzed acetylation of NF-κB p50. These findings indicate a potential anti-inflammatory function of HDAC6 in NF-κB signaling.
