Bioinformatics analysis of ferroptosis-related hub genes and immunoinfiltration in myocardial ischemia/reperfusion following heart transplantation.
Article in BMC cardiovascular disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
backgroundIschemia/reperfusion (I/R) is an inevitable pathophysiological process during heart transplantation, and ferroptosis is an important pathogenic mechanism. Unlike other modes of cell death, ferroptosis depends on the accumulation of iron within the cell and the oxidative degradation of polyunsaturated fatty acids. Dysregulation of this pathway has been linked to the progression of multiple pathological conditions, making it an attractive target for therapeutic intervention. Therefore, this study aims to explore the effect of ferroptosis on I/R during heart transplantation.
methodsGEO2R was applied to identify differentially expressed genes (DEGs) obtained from GSE50884 data, which was involved in I/R and heart transplantation. And ferroptosis-related DEGs (FRDEGs) were screened by venn diagram with ferroptosis-related genes downloaded from FerDb database. FRDEGs was enriched and analyzed by GO and KEGG, and hub genes related to ferroptosis were screened by Cytoscape software and database STRING. Additionally, considering the relationship between ferroptosis and immunity, CIBERSORTx was to analyze the infiltration of 22 kinds of immune cells in I/R during heart transplantation, and the correlation between each immune cell and the expression of FRDEGs was also discussed. Finally, the mouse model of heart transplantation with I/R was constructed, and the hub genes was verified by RT-qPCR and western blot.
results12 FRDEGs were identified out of 327 DEGs in GSE50844, which were mainly involved in ferroptosis and other pathways. Three hub genes (SLC7A11, PSAT1, ASNS) were obtained by the degree algorithm of cytohubba plug-in. Immunoinfiltration analysis showed that 16 of 22 immune cells changed, and the immune score of heart transplantation with I/R was higher than that without I/R. In addition, hub genes exhibited significant correlation with Eosinophils, NK cells resting, Dendritic cells resting, NK cells activated and T cells CD4 memory activated. We verified the expression of SLC7A11, PSAT1 and ASNS was higher than that in normal tissues using RT-qPCR and western blot in mouse models of heart transplantation with I/R, companied by ferroptosis aggravated is involved.
conclusionsIn short, ferroptosis is involved in I/R injury during heart transplantation, which is related to immune cell infiltration. Three hub genes (SLC7A11, PSAT1 and ASNS) identified in this study provide therapeutic targets for ameliorating I/R injury in heart transplantation.
