The arylstibonic acid compound NSC13746 disrupts B-ZIP binding to DNA in living cells.
Article in European journal of cell biology, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
The inhibition of DNA binding of basic leucine zipper (B-ZIP) transcription factors is a clinically relevant molecular target. Our laboratory has previously reported two methods of inhibiting B-ZIP DNA binding in solution: 1) an arylstibonic acid compound that binds to the basic region, stabilizes the B-ZIP dimer, and prevents B-ZIP DNA binding and 2) dominant negative proteins, termed A-ZIPs, that heterodimerize with B-ZIP domains in a leucine zipper-dependent manner. To determine if these two agents also inhibit DNA binding in live cells, GFP-tagged B-ZIP domains and mCherry-tagged A-ZIP domains were transfected into NIH3T3 cells to assess protein localization and Fluorescence Recovery After nuclear Photobleaching (FRAP). FRAP, showed that all six GFP-B-ZIP domains examined recovered faster in the nucleus in the presence of drug that we interpret represents an inhibition of DNA binding. Faster recovery in the presence of the A-ZIP was leucine zipper dependent. The arylstibonic also induced a cytoplasmic localization of all B-ZIP domains while the A-ZIPs induced a leucine zipper-dependent cytoplasmic localization. Thus, the change in cellular localization of B-ZIP domains could be used as a high-throughput assay for inhibitors of B-ZIP DNA binding. Additionally, the arylstibonic acid compound was cytostatic in clear cell sarcoma cells, which express a chimera between the B-ZIP domain of ATF-1 and N-terminal activation domain of EWS but not in K562 cells that express a non-B-ZIP containing chimeric protein BCR-ABL. These studies suggest that arylstibonic acid compounds or other small molecules capable of inhibiting B-ZIP DNA binding could be valuable anticancer agents.
