Spatiotemporal transcriptomic insights into ferroptosis and TFRC-linked immune interactions in ischemia-reperfusion acute kidney injury.

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
Acute kidney injury (AKI) is a common and critical clinical condition with complex pathogenesis and limited early intervention options. Ferroptosis, an iron-dependent form of cell death driven by lipid peroxidation, plays a pivotal role in AKI development. This study aimed to investigate ferroptosis-related gene expression, spatial distribution, and immune interactions in AKI to identify potential therapeutic targets. We analyzed gene expression changes in a mouse model of ischemia-reperfusion-induced AKI and constructed a machine learning-based diagnostic model. This model identified five ferroptosis-related genes (TFRC, TXNRD1, SLC39A14, GCLM, and HMOX1) closely associated with immune cell infiltration. Integration of single-cell and spatial transcriptomics revealed that these genes were predominantly expressed in proximal tubule cells. Notably, TFRC exhibited distinct spatial proximity to infiltrating macrophages. In vivo, administration of the ferroptosis inhibitor NSC306711 significantly reduced macrophage infiltration and renal injury, as confirmed by immunofluorescence. In vitro, co-culture experiments showed that TfR1 degradation alleviated hypoxia-reoxygenation injury in tubular cells and attenuated immune cell activation. This study highlights the central role of ferroptosis in AKI pathogenesis and its interaction with immune components in the renal microenvironment. Targeting ferroptosis, particularly TFRC, may offer a promising strategy to mitigate kidney injury and immune activation in AKI.
