Arginine methylation-dependent stabilization of SUV39H1 promotes breast cancer growth.
Article in Oncogene, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Suppressors of variegation 3-9 homolog 1 (SUV39H1), the enzyme responsible for establishing histone H3 lysine 9 trimethylation (H3K9me3) marks in heterochromatin, is frequently dysregulated in cancers. However, the mechanisms underlying SUV39H1 dysregulation in breast cancer remain largely unclear. Here, we report that protein arginine methyltransferase 1 (PRMT1) directly interacts with SUV39H1 and dimethylates it at arginine 378 (R378). PKC signaling-mediated phosphorylation of SUV39H1 at S391 enhances this interaction, thereby promoting its methylation. Notably, PRMT1 binds to SUV39H1 with higher affinity and binding free energy than MDM2, causing a structural clash that blocks MDM2-mediated ubiquitination of SUV39H1. Moreover, methylated SUV39H1 exhibits enhanced H3K9me3 methyltransferase activity and promotes tumor cell growth. A SUV39H1-derived peptide (TAT-SUV-peptide) disrupts the interaction between PRMT1 and SUV39H1, thereby reducing SUV39H1 methylation. Administration of TAT-SUV-peptide remarkably suppresses mammary tumor growth. Taken together, our findings reveal a critical phosphorylation-methylation-ubiquitination axis in controlling SUV39H1 stability and highlight its therapeutic potential through targeting SUV39H1 methylation.
