CRISPR screens identify PRMT7 as a therapeutic target to enhance T cell-mediated killing in breast cancer.

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
Genome-wide association studies (GWAS) have identified more than 220 loci associated with breast cancer susceptibility, yet identifying effector genes, their modes of action and prioritising therapeutic targets remains a significant challenge. To address this, we performed pooled CRISPR knockout and inhibition screens to identify genes at risk loci that influence cytotoxic T lymphocyte (CTL) killing of MCF7 breast cancer cells in co-culture. These screens uncovered 33 candidate modulating genes, of which we validated six by single gene editing in two cell lines. Deletion of IRF1, ATF7IP, and CASP8 conferred resistance to CTL killing, while disruption of CFLAR, CREBBP and PRMT7 enhanced sensitivity. Analysis of clinical data showed that PRMT7 expression is negatively correlated with CD8+ infiltration and survival in breast cancer patient cohorts. Pharmacological inhibition of PRMT7 sensitized breast cells to CTL killing in vitro, and Prmt7-deficient tumors exhibited reduced growth and increased CD8+ T cell infiltration in immunocompetent mice. Enhanced Prmt7-dependent tumor growth was not observed in immunodeficient mice, implicating Prmt7 in immune evasion. This study underscores the utility of CRISPR screens for high-throughput functional follow-up of GWAS findings and identifies PRMT7 inhibition as a promising therapeutic strategy.
