EZH2 directs HER2+ breast cancer progression through the modulation of epithelial plasticity.
Article in EMBO reports, 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
Breast cancer remains a leading cause of death among women, with the HER2+ subtype being particularly aggressive due to acquired resistance to HER2-targeted therapies. Enhancer of Zeste Homolog 2 (EZH2), the catalytic subunit of Polycomb Repressive Complex 2, represses the expression of genetic programs crucial for differentiation, proliferation, and apoptosis. To investigate the role of EZH2 in HER2+ tumor progression, we crossed a genetically engineered mouse model of HER2-driven breast cancer with a conditional Ezh2 knockout strain and showed that Ezh2 is essential for accelerating tumor initiation and metastatic dissemination. Combined bulk and single cell RNA sequencing analyses revealed a significant downregulation of basal cell populations in the absence of Ezh2, and an upregulation of luminal progenitor cell populations, driven by crucial transcription factors such as Esr1. Further, inhibition of EZH2 in vitro resulted in increased expression of ER in HER2+ human breast cancer cell lines and conferred sensitivity to Tamoxifen. These findings demonstrate that EZH2 dictates cancer plasticity and provides rationale for combining EZH2 inhibitors with endocrine therapies to improve HER2+ breast cancer outcomes.
