GDF15 Improves Renal Injury Induced by Ectopic Lipid Deposition via AMPK/SIRT1 Pathway-Mediated Autophagy.
Article in Metabolites, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesObesity precipitates excessive lipid accumulation within the kidney, culminating in ectopic lipid deposition that compromises target organ function through lipotoxicity. Given the pivotal role of GDF15 in lipid metabolism, this study aims to determine whether GDF15 can ameliorate ectopic lipid deposition and mitigate the resulting renal injury.
methodsC57BL/6J mice were used to establish a high-fat diet-induced obesity model. Based on Lee's index, the mice were categorized into a diet-induced obesity group and an obesity-resistant group. Subsequently, the diet-induced obesity group received an injection of AAV-shGFRAL to knock down the GFRAL receptor.
resultsIn obesity resistant mice, ectopic lipid deposition in the kidneys was markedly reduced, accompanied by decreased expression of the renal injury marker KIM-1 and significantly elevated levels of GDF15. Modulation of the GDF15-GFRAL axis demonstrated that reduced autophagy levels led to increased lipid accumulation and exacerbated renal injury. Conversely, GDF15 activates the AMPK/SIRT1 signaling pathway to promote cellular autophagy, thereby mitigating renal damage induced by ectopic lipid deposition. Consistent with this mechanism, the suppression of autophagy results in the aggravation of renal injury caused by ectopic lipid accumulation.
conclusionsGDF15 ameliorates renal injury induced by ectopic lipid deposition in the kidney primarily through activation of autophagy via the AMPK/SIRT1 signaling pathway.
