1 · What the graph read from it

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.

2 · The registry

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

purposeCalcium oxalate (CaOx) crystal deposition is the major pathological process of kidney stone formation and causes renal tubular injury. However, the molecular mechanisms and metabolic alterations involved remain unclear. This study aimed to identify key molecules and pathways associated with CaOx crystal-induced renal injury.

methodsA mouse model of renal CaOx crystal deposition was established by glyoxylate (Gly) administration. Kidney tissues from CaOx crystal-bearing and control mice were analyzed using integrated proteomic and metabolomic approaches. Differentially expressed proteins and metabolites were identified by bioinformatics analyses, including Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment and protein-metabolite correlation analysis. The candidate proteins were validated by immunohistochemistry and Western blotting, and their functions were evaluated in COM-treated HK-2 cells.

resultsMulti-omics analysis revealed significant alterations in mitochondrial energy metabolism, redox homeostasis, mineral absorption, and apoptosis-related pathways. Four candidate proteins, apoptosis-inducing factor mitochondria-associated 1 (AIFM1), succinyl-CoA ligase ADP-forming beta subunit (SUCLA2), isocitrate dehydrogenase 2 (IDH2), and pyruvate dehydrogenase E1 subunit beta (PDHB), were downregulated in CaOx crystal-bearing kidneys. The overexpression experiments showed that IDH2 provided the strongest protection against COM-induced tubular injury and mitochondrial reactive oxygen species accumulation, while SUCLA2 and PDHB showed moderate effects.

conclusionMitochondrial energy metabolism dysfunction is a key feature of CaOx crystal-induced renal injury. IDH2 may represent a potential protective regulator and therapeutic target for CaOx-related kidney injury.
