DPP8 and DPP9 promote tubular epithelial cell ferroptosis in acute kidney injury.
Article in European journal of medical research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
Renal tubular epithelial cells (TECs) death plays vital role in acute kidney injury (AKI). However, the effects and regulated mechanisms of ferroptosis within TECs during AKI has not been fully elucidated. Here, we found evidence that ferroptosis pathway was significant enriched in injured TECs and associated with excessive expression of Dpp8 and Dpp9, observed in snRNA-seq of AKI mice. Consistently, elevated protein levels of DPP8 and DPP9 were observed in TECs from both AKI patients and murine models, concomitant with ferroptotic cell death. TC-E5007, a combined inhibitor of DPP8 and DPP9, could significantly protect TECs from ferroptosis in vivo, thereby improving the renal function, alleviating tubulointerstitial injury and reducing renal inflammation in cisplatin-related AKI mice. Furthermore, in vitro siRNA-mediated knockdown of DPP8 and DPP9 decreased ferroptosis in cisplatin-treated HK-2 cells, respectively. Collectively, our findings reveal DPP8 and DPP9 as regulators of ferroptosis in TECs and propose them as promising therapeutic targets for mitigating AKI progression.
