Ancestry-linked stromal variations impact breast epithelial cell invasion.
Article in iScience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 disproportionately affects women of African ancestry (AA) in part due to biological factors that affect disease outcome. A cell population that expresses PROCR, ZEB1, and PDGFRα (PZP) was recently found to be enriched in breast stroma from healthy AA donors, but only in tumor-adjacent tissues from donors of European ancestry (EA). Here, we show that PZP cells conferred invasive capacity to epithelial cells of both AA and EA origin in 3D cell models wherein cells exhibited leader-follower behaviors during extracellular matrix invasion. Epithelial cell invasion stemmed from a combination of AKT activation and fibronectin deposition by PZP cells. Although AKT activation in epithelial cells alone was insufficient to enhance invasion, blocking AKT activation markedly reduced invasive capacity. These findings point to the germaneness of intrinsic differences in normal breast tissues, such as PZP cell enrichment, in furthering understanding of the molecular basis for worse prognosis in patient cohorts.
