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

backgroundCisplatin is widely used in clinical practice, but its nephrotoxicity severely limits its use. Previous studies have shown that cisplatin-induced acute kidney injury (AKI) is closely related to mitochondrial damage and that alleviating mitochondrial dysfunction can alleviate cisplatin-induced AKI. Methylcrotonyl‑CoA carboxylase 2 (MCCC2) is mainly located in mitochondria, where it catalyzes the catabolism of leucine and maintains mitochondrial function; however, the role of MCCC2 in cisplatin-induced renal injury has not yet been studied.

methodsIn vitro, the expression of MCCC2 was manipulated by transfecting HK-2 cells with lentiviruses, and changes in the acetoacetate content, cell viability, apoptosis, oxidative stress, mitochondrial function, and mitochondrial biogenesis were evaluated. In vivo, MCCC2 overexpression was manipulated by adeno-associated viruses, and serum and kidneys were collected for subsequent experiments to detect changes in renal function, tissue damage, apoptosis, oxidative stress, mitochondrial damage, and mitochondrial biogenesis.

resultsWe found that MCCC2 was downregulated in cisplatin-induced AKI models. In vitro, leucine catabolism was inhibited by cisplatin, while overexpression of MCCC2 supported leucine catabolism, upregulated peroxisome proliferator-activated receptor gamma coactivator 1-alpha expression, promoted mitochondrial biogenesis, improved mitochondrial function, and alleviated cisplatin-induced apoptosis and oxidative stress in HK-2 cells. In contrast, the knockdown of MCCC2 exacerbated these effects, while leucine deprivation reversed the effects of MCCC2 overexpression on mitochondrial function and biogenesis. In vivo, the overexpression of MCCC2 promoted mitochondrial biogenesis, maintained the integrity of the mitochondrial structure and function, and alleviated cisplatin-induced AKI.

conclusionMCCC2 supported leucine catabolism and promoted mitochondrial biogenesis, providing a new therapeutic strategy for cisplatin-induced AKI.
