Exosome-mediated effects of BRCA1 on cardiovascular artery disease.
Article in Cell biology and toxicology, 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
The progression of coronary artery disease atherosclerosis (CAD) is closely associated with cardiomyocyte apoptosis and inflammatory responses. This study focused on investigating the impact of BRCA1 in exosomes (Exo) derived from M1 macrophages on CAD. Through the analysis of single-cell RNA-seq datasets, significant communication between macrophages and cardiomyocytes in CAD patients was observed. BRCA1, identified as a significant apoptosis-related gene, was pinpointed through the assessment of differential gene expression and weighted gene co-expression network analysis (WGCNA). Experimental procedures involved BRCA1 lentivirus transfection of M1 macrophages, isolation of Exo for application to cardiomyocytes and smooth muscle cells, cell viability assessments, and characterization of Exo. The results showed that BRCA1-Exo from M1 macrophages induced cardiomyocyte apoptosis and affected smooth muscle cell behavior. In vivo studies further supported the exacerbating effects of BRCA1-Exo on CAD progression. Overall, the involvement of Exo carrying BRCA1 from M1 macrophages is evident in the induction of cardiomyocyte apoptosis and the regulation of smooth muscle cell behaviors, thereby contributing to CAD atherosclerosis progression. These findings unveil novel molecular targets that could have potential implications for CAD treatment strategies.
