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

Mitochondrial dysfunction is a crucial event in acute kidney injury (AKI), leading to a metabolic shift toward glycolysis and increased lactate production. Lactylation, a posttranslational modification derived from lactate, plays a significant role in various cellular processes, yet its implications in AKI remain underexplored. Here, a marked increase in lactate levels and pan-Kla levels are observed in kidney tissue from AKI patients and mice, with pronounced lactylation activity in injured proximal tubular cells identified by single-cell RNA sequencing. The lactylation of aldehyde dehydrogenase 2 (ALDH2) is identified at lysine 52 (K52la), revealing that ALDH2 lactylation exacerbates tubular injury and mitochondrial dysfunction. Conversely, the ALDH2 K52R mutation alleviates these injuries in HK-2 cells and adeno-associated virus-infected kidney tissues in mice. Furthermore, ALDH2 lactylation can be modulated by upregulating SIRT3 in vivo and in vitro, which reduces ALDH2 lactylation, mitigating tubular injury and mitochondrial dysfunction. Mechanistically, immunoprecipitation-mass spectrometry analysis demonstrates an interaction between ALDH2 and prohibitin 2 (PHB2), a crucial mitophagy receptor. ALDH2 lactylation promotes the ubiquitination-proteasomal degradation of PHB2 to inhibit mitophagy and worsen mitochondrial dysfunction. These findings highlight the critical role of endogenous lactate in AKI and propose ALDH2 lactylation as a potential therapeutic target.
