The Antimalarial Drug Pyronaridine Inhibits Topoisomerase II in Breast Cancer Cells and Hinders Tumor Progression
Article in Clinical cancer drugs, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
backgroundBreast cancer is the most frequently diagnosed cancer in women worldwide. Pyronaridine (PND), an antimalarial drug, was shown to exert anticancer activity on seventeen different human cancer cells, seven from female breast tissue. Additionally, PND induced apoptosis
objectiveHere, we have further investigated PND's mode of action by using transcriptome analysis. Preclinical studies were also performed to determine whether PND could affect tumor progression in a human breast cancer xenograft in mice. Moreover, we assessed the combined efficacy of PND with well-known anticancer drugs.
methodsTranscriptome analyses of PND-treated cancer cells were performed. Topoisomerase II activity was evaluated by an
resultsThe transcriptome signatures suggested that PND might act as a topoisomerase II inhibitor. Thus, topoisomerase inhibition assays were performed, providing evidence that PND is a bona fide topoisomerase II inhibitor. Also,
conclusionThe findings provide evidence that PND is a topoisomerase II inhibitor and can hinder cancer progression in an animal model, further demonstrating PND's favorable characteristics as a repurposed anticancer drug.
