Functional analysis of the effect of isoimperatorin on human acute monocytic leukemia at the transcriptome level.
Article in Oncology letters, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Acute myeloid leukemia (AML), which is characterized by the aberrant proliferation of primitive and immature myelocytes within the bone marrow, represents the most prevalent subtype of leukemia in both adults and children. Isoimperatorin, a derivative of coumarins, has been reported to possess antitumor, antioxidative and anti-inflammatory activities. In the present study, the effects of isoimperatorin on human AML cells were evaluated. Tohoku Hospital Pediatrics-1 (THP-1) and AML-193 cells were treated with or without isoimperatorin. Subsequently, induction of apoptosis was detected by flow cytometry, whereas cell proliferation was assessed using Cell Counting Kit-8. Furthermore, the potential transcriptional regulatory effects of isoimperatorin on THP-1 cells were investigated using RNA sequencing and reverse transcription-quantitative PCR (RT-qPCR). Isoimperatorin significantly induced apoptosis and inhibited cell proliferation in the AML cells. Furthermore, transcriptome sequencing analysis demonstrated 688 differentially expressed genes between isoimperatorin-treated THP-1 cells and untreated controls. Gene Ontology annotation enrichment analysis, Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis and Gene Set Enrichment Analysis indicated that isoimperatorin altered the expression genes associated with 'cell migration' and 'cell motility'. The compound primarily regulated signaling pathways, including the 'calcium signaling pathway', 'microRNA in cancer' and 'MAPK signaling pathway', while influencing biological processes related to 'cancer biology', 'metabolic pathways' and 'immune responses'. These findings were verified using RT-qPCR. Collectively, the present results elucidated the potential effects of isoimperatorin on AML and provided a theoretical foundation for the clinical treatment of AML.
