Malic enzyme 3 mediated the effects of malic acid on intestinal redox status and feed efficiency in broilers.
Article in Journal of animal science and biotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundIntestinal oxidative stress serves as an endogenous host defense against the gut microbiota by increasing energy expenditure and therefore decreasing feed efficiency (FE). Several systems coordinately regulate redox balance, including the mitochondrial respiratory chain, nicotinamide adenine dinucleotide phosphate (NADPH) oxidase, and different antioxidants. However, it remains unclear which redox balance compartments in the intestine are crucial for determining FE.
resultsIn this study, we first screened the key targets of different metabolites and redox balance-related gene expression in broiler ceca. We then constructed a mouse colitis model to explore malic acid (MA) ability to alleviate intestinal inflammation. We further used controlled release technology to coat MA and investigated its effects on the intestinal redox status and FE in vivo. Finally, we examined the underlying mechanism by which MA modulated redox status using a porcine intestinal epithelial cell jejunum 2 (IPEC-J2) cell model in vitro. Our results demonstrated that the MA/malic enzyme 3 (ME3) pathway may play an important role in reducing oxidative stress in the broiler cecum. In addition, colon infusion of MA attenuated inflammatory phenotypes in the dextran sulfate sodium salt (DSS) induced mouse colitis model. Then, dietary supplementation with controlled-release MA pellet (MAP) reduced the feed to gain (F/G) ratio and promoted chicken growth, with reduced oxidative stress and increased bacterial diversity. Finally, the in vitro IPEC-J2 cell model revealed that ME3 mediated the effect of MA on cellular oxidative stress.
conclusionIn summary, our study firstly revealed the important role of the MA/ME3 system in the hindgut of broiler chickens for improving intestinal health and FE, which may also be crucial for the implications of colon inflammation associated diseases.
